Abstract:

Supercapacitors have attracted great attention because of their high power density, long life cycle and high efficiency. They can be generally classified into two types: electrical double-layer capacitors (EDLCs) and pseudocapacitors. Compared with pseudocapacitors, EDLCs have a very fast charge/discharge rate, higher power density, higher coulombic efficiency and longer cycle life. Recently, in order to meet the requirements of portable and wearable electronics, supercapacitor development is moving towards flexible and stretchable solutions. This thesis presents the design, fabrication, perfo

Abstract:

The study on flexible, ultrathin and safe energy storage devices such as supercapacitors or batteries is an emerging area to “power-up” the next-generation of portable and flexible electronics such as mobile phones, computers, displays, wearable and implantable biomedical devices. In general, a supercapacitor is composed of two electrodes, electrolyte, separator and current collectors and it can store and deliver charge at relatively high rates. The challenge to design such supercapacitors to be flexible lies in the development of flexible electrodes and leak-proof electrolytes, as well as, th

Abstract:

The development of energy storage devices has represented a significant technological challenge for the past few years. Electrochemical double-layer capacitors (EDLCs), also named as supercapacitors, are a likely competitor for alternative energy storage because of their low-cost, high power density, and high fast charge/discharge rate. The recent development of EDLCs requires them to be lightweight and flexible. There are many fabrication techniques used to manufacture flexible EDLCs, and these methods can include pre-treatment to ensure more efficient penetration of activated carbon (AC) pat

The great popularity of portable, wearable, and implantable smart electronics has intensively boosted the development of flexible miniaturized power supplies.

Abstract:

We design a facile approach to investigate the role benzene derivatives play in the capacitance enhancement of graphene-based supercapacitors. The main reason is attributed to the pseudocapacitance of the aromatic molecules rather than the former one. Meanwhile, we find that the para and ortho substituted benzene derivatives contribute much more than the meta substituted ones. In addition, we fabricate an all-solid-state flexible MSC based on metal-reduced GO. The as-fabricated MSC shows high areal capacitance and excellent reliability, which makes it a promising energy storage candidate for

While significant effort has been directed towards increasing PEDOT:PSS conductivity in transparent films, very little nanoscale, morphological consideration has been applied to micron-scale PEDOT:PSS materials. As a result, PEDOT:PSS conductivity often decreases in micron-scale materials, and the polymer has been largely overlooked as a high performance material in practical applications. I

Abstract:

The development of synthetic life once envisioned by Feynman and Flynn many decades ago has stimulated significant research in materials science, biology, neuroscience, robotics, and computer science. The cross-disciplinary effort and advanced technologies in soft miniature robotics have addressed some of the significant challenges of actuation, sensing, and subsystem integration. An ideal Soft motile miniaturised robot (SMMRs) has innovative applications on a small scale, for instance, drug delivery to environmental remediation. Such a system demands smart integration of micro/nano components
