| Abstract Scope |
Rechargeable zinc-ion batteries (ZIBs) based on near-neutral aqueous electrolytes have been actively researched in recent years as an alternative large-scale stationary storage device for their outstanding merits in energy density, conductivity, safety, cost, and environmental impact. Although remarkable materials advancements have been reported recently, particularly in the area of Zn-ion storing cathodes, the commercialization of ZIBs is still being hindered by several key technical issues such as capacity, degradation and self-discharge, etc. The focus of this presentation is to specifically address the current development and critical challenges in practical ZIB electrodes and provide candid opinions for future ZIB commercialization. The presentation starts with a brief introduction to ZIBs and their unique advantages, and then moves onto the current understanding of Zn-ion storage mechanisms, recent progress and critical issues associated with cathodes. Finally, the presentation is concluded with perspectives and directions of future ZIB cathode development. |
