Abstract:

As the world moves towards sustainable and renewable energy sources, there is a need for reliable energy storage systems. A good candidate for such an application could be to improve secondary aqueous zinc–manganese dioxide (Zn-MnO2) batteries. For this reason, different aqueous Zn-MnO2 battery technologies are discussed in this short review, focusing on how electrolytes with different pH affect the battery. Improvements and achievements in alkaline aqueous Zn-MnO2 batteries the recent years have been briefly reviewed. Additionally, mild to acidic aqueous electrolyte employment in Zn-MnO2 batt

Abstract:

Zinc|Manganese Dioxide (Zn|MnO2) are widely available as primary batteries for use in small-scale consumer electronics because of its low cost and high energy density. The last decade has seen a resurgence in research to make this chemistry rechargeable by materials engineering, additives and experimenting with various electrolytes. These important contributions have showed that Zn|MnO2 has all the prerequisites to be a post-lithium solution for grid-scale storage. At Urban Electric Power, we have been commercializing proton-insertion Zn|MnO2 batteries in cylindrical and prismatic form factors

Abstract:

Abstract The rapid development of printed and microscale electronics imminently requires compatible micro-batteries (MBs) with high performance, applicable scalability, and exceptional safety, but faces great challenges from the ever-reported stacked geometry. Herein the first printed planar prototype of aqueous-based, high-safety Zn//MnO2 MBs, with outstanding performance, aesthetic diversity, flexibility and modularization, is demonstrated, based on interdigital patterns of Zn ink as anode and MnO2 ink as cathode, with high-conducting graphene ink as a metal-free current collector, fabricate

Abstract:

The mechanism of a novel desulfurization method using spent Zn-MnO2 batteries has been studied by X-ray diffraction(XRD), scanning electronic microscopy (SEM), energy dispersive spectrometry (EDS) and the experiments of SO2 absorption. The XRD results show that the positive electrode of spent Zn-MnO2 batteries consists of a mixture of α-MnO2, Mn2O3 and Mn3O4 phase. The SEM results show that micropores and microparticles are observed in the positive electrode surface, the relative content of zinc and graphite increases in the positive electrode after discharging according to EDS.

Abstract:

Aqueous Zn-ion batteries has attracted great attention in recent years, as a promising candidate for grid energy storage applications. An aqueous system offers intrinsic safety, high ionic conductivity contributing improved power capability and raw materials that are more earth abundant and environment friendly. Numerous promising reports haven been focusing on the Zn/MnO2 system owing to its low cost, moderate discharge potentials and with improved reversibility in the mild aqueous electrolyte. However, many questions remain unanswered regarding its reaction mechanism. The different reaction

Abstract:

Abstract The low cell voltage and capacity of conventional Zn-MnO2 batteries often result in limited energy density. In this study, we assembled a Zn-MnO2 battery based on the acid-alkaline electrolyte decoupled concept and reversible MnO2/Mn2+ deposition/dissolution chemistry to increase the cell voltage and capacity. We used a Na+ ion conducting NASICON ceramic membrane in the battery to decouple the acid and alkaline electrolytes effectively. The assembled Zn-MnO2 battery demonstrated a cell voltage of 2.43 V and a coulombic efficiency (CE) of 90% at a current density of 0.2 mA/cm2. It also

Abstract:

Zinc (Zn)–manganese dioxide (MnO2) rechargeable batteries have attracted research interest because of high specific theoretical capacity as well as being environmentally friendly, intrinsically safe and low-cost. Liquid electrolytes, such as potassium hydroxide, are historically used in these batteries; however, many failure mechanisms of the Zn–MnO2 battery chemistry result from the use of liquid electrolytes, including the formation of electrochemically inert phases such as hetaerolite (ZnMn2O4) and the promotion of shape change of the Zn electrode.

Abstract:

The slow diffusion dynamics hinder aqueous MnO2/Zn batteries’ further development. Here, a Ni/Fe bimetallic co-doped MnO2 (NFMO) cathode material was studied by density functional theory (DFT) calculation and experimental characterization techniques, such as cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT) and electrochemical impedance spectra (EIS). The results indicated that the energy band structure and electronic state of MnO2 were effectively optimized due to the simultaneous incorporation of strongly electronegative Ni and Fe ions. Consequently, the NFMO cat

Benefiting from N element doping, the conductivity of N-MnO2 nanorods (NRs) electrode has been improved and the dissolution of the cathode during cycling can be relieved to some extent.
