Abstract:
The use of nonrenewable fossil fuels for energy has increased in recent decades, posing a serious threat to human life. As a result, it is critical to build environmentally friendly and low-cost reliable and renewable energy storage solutions. The supercapacitor is a future energy device because of its higher power density and outstanding cyclic stability with a quick charge and discharge process. Supercapacitors, on the other hand, have a lower energy density than regular batteries. It is well known that the electrochemical characteristic of supercapacitors is strongly dependent on electrode materials. The current review highlights advance in the TMOs for supercapacitor electrodes. In addition, the newly discovered hybrid/pseudo-supercapacitors have been discussed. Metal oxides that are employed as electrode materials are the focus of this study. The discovery of nanostructured electrode materials continues to be a major focus of supercapacitor research. To create high-performance electrode materials from a morphological standpoint, various efforts have been attempted. Lastly, we analyze the supercapacitor’s evolving trend and our perspective for the future generations of supercapacitors.

Abstract:
Application of energy storage systems such as supercapacitors can not be separated from the magnetic fields effect. In the last decade, it’s rare to find research reports about various low magnetic field effects on supercapacitor performance. Asymmetric supercapacitors based on MnO2-Carbon were made to analyze its electrochemical performance changes by magnetic field in 0-50 mT. Magnetic field was applied in flow direction from cathode (MnO2-C) to anode (C) during electrochemical performance test using Galvanostatic Charge-Discharge (C-D) instrument. The electrochemical performance was increasing in charging (91%) and discharging (22%) time of asymmetric supercapacitors. Impressively, the 50 mT magnetic field showed a high specific capacitance of 61.9 F/g at 0.1 A/g. The supercapacitor system delivers specific energy (17.8 Wh/kg), specific power density (329.72 W/kg), and outstanding stability (79% in 50 cycles). The electrochemical improvement by magnetic field indicates a highly promising application of this method in future supercapacitor devices.

Abstract:
Supercapacitors are the best choice when there is a need to deliver high power to the consumer or to store energy. Hybrid supercapacitors with their beneficial characteristics can somewhat overcome the basic lack of batteries, that is the low power density, and when supercapacitors are combined with batteries, the current maximum power can be increased and the lifetime extended. The number of research studies on development of new materials and construction technologies for supercapacitors has been increasing steadily in recent years. As a result, production of commercial devices and their applications are constantly growing, with improved product properties. Here we present the current state of development of supercapacitors as highly promising energy storage systems by an overview of operation principles, main components and various electrode materials and electrolytes, as well as description of different modes of production. A special attention was paid to the need of a good match of the active material and electrolytes, in order to achieve high capacity of the device. The electrode/electrolyte phase optimization is the key to maximizing characteristics of a supercapacitor, especially the capacitance. In selecting the materials, requirements of the final application must be considered, such as the specific energy and power, energy and power density, and service life-time. In addition to material selection, design and optimization of the cell configuration provide new opportunities for development of hybrid battery/supercapacitor systems. Demand for such systems will increase in future, when using a battery or a supercapacitor alone will not be able to meet specific needs, such as the energy density, number of charge and discharge cycles or voltage. Finally, equally important as the development of materials and cells, are the electrode production technology and the cell construction, which need to be optimized in order to improve supercapacitor properties.

Abstract:
Since their discovery, MXenes have conferred various intriguing features because of their distinctive structures. Focus has been placed on using MXenes in electrochemical energy storage including a supercapacitor showing significant and promising development. However, like other 2D materials, MXene layers unavoidably experience stacking agglomeration because of its great van der Waals forces, which causes a significant loss of electrochemically active sites. With the help of MoS2, a better MXene-based electrodecan is planned to fabricate supercapacitors with the remarkable electrochemical performance. The synthesis of MXene/MoS2 and the ground effects of supercapacitors are currently being analysed by many researchers internationally. The performance of commercial supercapacitors might be improved via electrode architecture. This analysis will support the design of MXene and MoS2 hybrid electrodes for highly effective supercapacitors. Improved electrode capacitance, voltage window and energy density are discussed in this literature study. With a focus on the most recent electrochemical performance of both MXene and MoS2-based electrodes and devices, this review summarises recent developments in materials synthesis and its characterisation. It also helps to identify the difficulties and fresh possibilities MXenes MoS2 and its hybrid heterostructure in this developing field of energy storage. Future choices for constructing supercapacitors will benefit from this review. This review examines the newest developments in MXene/MoS2 supercapacitors, primarily focusing on compiling literature from 2017 through 2022. This review also presents an overview of the design (structures), recent developments, and challenges of the emerging electrode materials, with thoughts on how well such materials function electrochemically in supercapacitors.

Abstract:
Concept of structural supercapacitors, based on carbon fiber reinforced polymer composites, has been introduced that can act as a structural load bearing component as well as an electrical energy storing device simultaneously. This multifunctional carbon fiber reinforced structural supercapacitors are fabricated by using carbon fiber and glass fiber/filter paper as reinforcements and cross-linked polymer electrolyte as a matrix. Carbon fiber mats also simultaneously serve the role of electrodes in addition to reinforcements whereas the glass fiber mat/filter paper also acts as an insulator to avoid the short-circuiting of the carbon fiber electrodes. A polymer epoxy matrix is modified by introducing ions within the cross-linked structure in order to develop an optimized polymer electrolyte. Flexural tests of structural supercapacitor are conducted to evaluate the structural performance while charge/discharge tests are conducted to evaluate the electrochemical performance. Multifunctional structural supercapacitors are tested mechanically as well as electrochemically. A structural supercapacitor is fabricated showing simultaneously an energy density of 0.11 mWh m-3, a specific capacitance of 0.8 mF.cm-3 and a flexural modulus of 26.6 GPa simultaneously.

Abstract:
Electrode materials are the most important factors to verify the properties of the electrochemical supercapacitor. In this paper, the storage principles and characteristics of electrode materials, including carbon-based materials, transition metal oxides and conducting polymers for supercapacitors are depicted in detail. Other factors such as electrode separator and electrolyte are briefly investigated. Recently, several works are conducted on application of multiwalled carbon nanotubes (MWCNTs) and MWCNTs-based electrode materials for supercapacitors. MWCNTs serve in experimental supercapacitor electrode materials result in specific capacitance (SC) value as high as 135 Fg-1. Addition of pseudocapacitive materials such as transition metal oxides and conducting polymers in the MWCNTs results in electrochemical performance improvement (higher capacitance and conductivity). The nanocomposites of MWCNTs and pseudocapacitive materials are the most promising electrode materials for supercapacitors because of their good electrical conductivity, low cost and high mass density.

Abstract:
One of the major elements in determining the supercapacitor performance is the development of a nano-layered structure through facilitating the surface-dependent electrochemical reaction processes. Carbon-based nanomaterials especially graphene, has attracted tremendous interest in electrical charge and power sources including supercapacitor because of their exceptional properties, which include high conductivity and large specific surface area. In this paper, the effect of polytetrafluoroethylene (PTFE) binder ratio (1, 5, 10, and 15 wt. %) on the electrochemical performance of graphene supercapacitor are evaluated. In addition, the facile and scalable preparation of graphene electrodes by using low-cost slurry technique is proposed. From the conducted experimental works, it was found that the fabricated graphene electrodes exhibit superior electrochemical properties for supercapacitor applications with a specific gravimetric capacitance of up to 373 F g−1. Moreover, the graphene electrode presented excellent cyclic stability with 99 % specific capacitance retention after 10,000 charge/discharge cycles hence promising for long‐lasting supercapacitors. The outcomes from the deliberated study serve as the basis of knowledge in the development of a cost-effective graphene-based materials production for energy storage devices.

Abstract:
In recent years, extensive investigations have focused on the study and improvement of supercapacitor electrode materials. The electric devices produced with these materials are used to store energy over time periods ranging from seconds to several days. The main factor that determines the energy storage period of a supercapacitor is its self-discharge rate, i.e., the gradual decrease in electric potential that occurs when the supercapacitor terminals are not connected to either a charging circuit or electric load. Self-discharge is attenuated at lower temperatures, resulting in an increased energy storage period. This paper addresses the temperature-dependence of self-discharge via a systematic study of supercapacitors with nominal capacitances of 1.0 and 10.0 F at DC potentials of 5.5 and 2.7 V, respectively. The specific capacitances, internal resistances, and self-discharge characteristics of commercial activated carbon electrode supercapacitors were investigated. Using cyclic voltammetry, the specific capacitances were determined to be 44.4 and 66.7 Fg−1 for distinct carbon electrode supercapacitors. The self-discharge characteristics were investigated at both room temperature and close to the freezing point. The internal resistances of the supercapacitors were calculated using the discharge curves at room temperature. The microstructures of the electrode materials were determined using scanning electron microscopy.

Abstract:
Due to the increasing demand for high power and reliable miniaturized energy storage devices, the development of micro-supercapacitors or electrochemical micro-capacitors have attracted much attention in recent years. This dissertation investigates several strategies to develop on-chip micro-supercapacitors with high power and energy density. Micro-supercapacitors based on interdigitated carbon micro-electrode arrays are fabricated through carbon microelectromechanical systems (C-MEMS) technique which is based on carbonization of patterned photoresist. To improve the capacitive behavior, electrochemical activation is performed on carbon micro-electrode arrays. The developed micro-supercapacitors show specific capacitances as high as 75 mFcm-2 at a scan rate of 5 mVs-1 after electrochemical activation for 30 minutes. The capacitance loss is less than 13% after 1000 cyclic voltammetry (CV) cycles. These results indicate that electrochemically activated C-MEMS micro-electrode arrays are promising candidates for on-chip electrochemical micro-capacitor applications. The energy density of micro-supercapacitors was further improved by conformal coating of polypyrrole (PPy) on C-MEMS structures. In these types of micro-devices the three dimensional (3D) carbon microstructures serve as current collectors for high energy density PPy electrodes. The electrochemical characterizations of these micro-supercapacitors show that they can deliver a specific capacitance of about 162.07 mFcm-2 and a specific power of 1.62mWcm-2 at a 20 mVs-1 scan rate. Addressing the need for high power micro-supercapacitors, the application of graphene as electrode materials for micro-supercapacitor was also investigated. The present study suggests a novel method to fabricate graphene-based micro-supercapacitors with thin film or in-plane interdigital electrodes. The fabricated micro-supercapacitors show exceptional frequency response and power handling performance and could effectively charge and discharge at rates as high as 50 Vs-1. CV measurements show that the specific capacitance of the micro-supercapacitor based on reduced graphene oxide and carbon nanotube composites is 6.1 mFcm-2 at scan rate of 0.01Vs-1. At a very high scan rate of 50 Vs-1, a specific capacitance of 2.8 mFcm-2 (stack capacitance of 3.1 Fcm-3) is recorded. This unprecedented performance can potentially broaden the future applications of micro-supercapacitors.

Abstract:
In this thesis, the synthesis and characterization of nitrogen-doped graphene (NG) and NG-Co3O4 composites are described. Moreover, the effect of airborne contamination and nitrogen doping on the capacitance of graphene was investigated. Firstly, nitrogen-doped thermally expanded graphene oxide (NtGO) was prepared by a facile thermal expansion and hydrothermal doping process. The thermal expansion process plays a vital role in improving the electrochemical performance of N-doped graphene by preventing its aggregation and improving its conductivity. The specific capacitance of NtGO is 270 F g-1 at a discharge current density of 1 A g-1 and the capacitance retention is 97 % after 2000 cycles at this current density. Secondly, a hierarchical electrode structure, consisting of cobalt oxide and nitrogen-doped graphene foam (NGF), has been fabricated with the aim of achieving enhanced charge storage performance. The Co3O4/NGF electrode shows an enhanced charge-storage performance, attributed to the 3D hierarchical structure and the synergistic effect of Co3O4 and NGF. The present study shows that specific capacitances as high as 451 F g-1 can be obtained, indicating that high-performance electrochemical capacitors can be made using electrode materials with advanced structures. Thirdly, a study of the differences between the capacitance of freshly exfoliated highly ordered pyrolytic graphite (HOPG, sample denoted FEG), HOPG aged in air (denoted AAG) and aged in an inert atmosphere (hereafter IAG) is presented in this work. Electrochemical impedance spectroscopy shows the FEG possesses a higher intrinsic capacitance (6.0 µF cm-2 at the potential of minimum capacitance) than AAG (4.3 µF cm-2) and IAG (4.7 µF cm-2). This change in capacitance is correlated with other physical changes of the sample, and attributed to contamination due to airborne hydrocarbons. Finally, the effect of N-doping of graphene prepared by chemical vapour deposition is investigated. The differential capacitance of PG and NG was measured by a microinjection-micromanipulator system. The quantum capacitance of PG and NG was calculated and discussed. The increase in differential capacitance with nitrogen-doping and the growth of the quantum capacitance of NG suggest that the increased capacitance of many electrodes of electrochemical capacitors is primarily due to the modification of the electronic structure of the graphene by the N dopant.

Abstract:
Several approaches have been used to develop carbon nanotube (CNT) based electrochemical supercapacitors. These approaches include the following: (a) stabilization and carbonization of ternary composites of polyacrylonitrile (PAN), poly (styrene co-acrylonitrile) (SAN) copolymer, and single wall carbon nanotubes (SWNTs); (b) SWNT membranes functionalized with aryl chloride, sodium sulfonate, aryl sulfonic acid, bis(3,5-di-tert-butylphenyl)5-aminobenzene-1,3-dioate, and 4,4 -methylenedianiline; and (c) pyrrole treated SWNTs. In addition nitric acid functionalized and heat-treated SWNT membranes have been studied. The electrochemical supercapacitor behavior of these membrane electrodes has been characterized by cyclic voltammetry, constant current charging-discharging, and impedance analysis in aqueous and ionic liquid electrolytes. Long term performance of selected electrodes has been evaluated. The surface area and pore size distribution was quantified by N2 gas adsorption/desorption and correlated with capacitance performance. The surface functional groups have been characterized by X-ray photoelectron spectroscopy. CNT electrode/electrolyte interaction has been characterized using contact angle measurements. Electrolyte absorption by the electrodes has also been characterized. Carbonized PAN/SAN/SWNT ternary composites exhibit double layer capacity of over 200 μF/cm2. By comparison, the double layer capacity of classical meso-porous carbons is in the range of 10-50 μF/cm2. The capacitance of functionalized SWNTs is up to 2 times that of the control bucky paper made from unfunctionalized SWNTs. Energy density of functionalized electrodes when evaluated in an ionic liquid is as high as 28 kJ/kg. High capacitance (up to 350 F/g) was obtained for pyrrole-treated functionalized SWNT membranes in 6 M KOH. This value is almost seven times that of the control bucky paper. Correlating the capacitance with surface area and pore size distribution, it was observed that macropores (pore width greater than 50 nm) play an important role for achieving high capacitance.

Abstract:
The paper describes the electrochemical behavior of supercapacitor electrodes in both positive and negative ranges. This study has become possible due to development of a special reference electrode, which is stable in aprotic electrolytes like, e.g., 1.3 M Et3MeNBF4 in acetonitrile. Three-electrode measurements have enabled us to find the boundary potentials for various nanoporous carbon materials to be then used in the supercapacitor technology. This article describes how the electrode size can be optimized to get the maximum charge value in the double electric layer at the electrode-electrolyte interface. Besides, we illustrate how the supercapacitor rated voltage can be increased up to 2.9 V as compared with the typical value of 2.7 V. This provides the 15 % increase in energy and power.

Abstract:
Abstract Throughout the integration of thin-film supercapacitors into composite structures, it is not only possible to store electric energy, but also to use them as sensor systems for strain detection. This paper describes the integration of thin-film supercapacitors into a glass-fiber composite structure, as well as their analyzation under mechanical load. The results are showing that there is a strong link between the mechanical load and the impedance spectra of the supercapacitor, enabling it to act as strain sensors. To characterize the samples, a four-point bending experiment is used, which features a well-defined constant load scenario with two interesting load states, a tensile and compression state, all in one sample. On each side one structural supercapacitor is integrated, placed far away from the neutral axis near to the outside layer, to be under the highest strain possible. Additionally, the device is placed in between the middle load entry points. During the four-point bending experiment the load is kept constant to run an electrochemical impedance spectroscopy to characterize the supercapacitor. This gives an inside view of what is happening in the supercapacitor. The experiments show a strong relation between the mechanical load and the electrochemical impedance measurements.

Abstract:
Supercapacitors are a strong candidate for high-power applications such as electric/hybrid vehicles and electronic devices due to their high power densities and high efficiency particularly at low temperatures. In these applications, supercapacitors are used as energy-storage devices with capability of providing the peak-power requirement. They are subject to heavy duty cycling conditions which result in significant heat generation inside the supercapacitors. Therefore, thermal management is a key issue concerning lifetime and performance of supercapacitors. Accurate modeling of temperature field inside supercapacitors is essential for designing an appropriate cooling system, meeting the safety and reliability requirements of power systems. The objective of this paper is to study the transient and spatial temperature distribution in supercapacitors, in which a supercapacitor product with prismatic structure, based on the activated carbon and organic electrolyte technology, was chosen for modeling. A multi-dimensional thermal and electrochemical coupled model was developed by a commercial software COMSOL. In this approach, the 3D energy equation was coupled with a 1D electrochemical model via the heat generation and temperature-dependent physicochemical properties, including diffusion coefficient and ionic conductivity of electrolyte ions. Location-dependent convection and radiation boundary conditions were applied to reflect different heat dissipation phenomena of all surfaces. This model is capable of predicting electrochemical performance and temperature distribution for different involved parameters. The results of this model can also be used to determine the optimum thermal management system for various supercapacitor applications.

Abstract:
Abstract Renewable energy and environmental preservation are two grand challenges in our society today. To address these two challenges, there is an increasing demand for energy storage devices made of green and biodegradable materials. State-of-the-art plant-based electrodes have problems of poor electrochemical performance, low reliability, and high manufacturing cost that pose major limitations in their use in flexible supercapacitors. In this research, a novel microwave irradiation synthesis is used to produce a high-performing electro-active lignin-based biomaterial. MnO2 particles are deposited on these lignin-based materials to impart pseudo-capacitance property. These electro-active materials were coated on an Al substrate and used as an anode with an AC-based cathode. A quasi-solid-state supercapacitor was assembled using a polymer-based gel electrolyte of PVA/H3PO4. SEM was performed to study morphology, porosity, and polydispersity of the lignin-based matrix. Cyclic voltammetry (CV) was employed to study the polarization resistance of the system. The cyclic charge-discharge (CCD) was performed to observe cyclic performance. The assembled supercapacitor exhibited a specific capacitance of 26 mF/g after 500 cycles with capacitance retention of ∼87% at 0.1 A/g. This work provides new insights into the synthesis of low-cost and scalable plant-based flexible supercapacitors.
