Abstract
En 中文
All -solid-state lithium batteries employing solid electrolyte instead of organic liquid electrolyte and separator have been regarded as one of the most favorable candidates for next generation energy storage devices due to their unparalleled safety and energy density. Recently, significant progresses have been made on developing suitable solid electrolytes for all -solid-state lithium batteries with high ionic conductivity, wide electrochemical window and favorable electrode compatibility. Nevertheless, owing to the brittle nature of inorganic solid electrolytes and limited mechanic property of solid polymer electrolytes, the typical thickness of solid electrolyte layers is excessively thick, which prevents further enhancing the energy density of all -solid-state rechargeable batteries. In this short review, we summary recent research progresses on solid electrolyte membranes based on wet coating, frame support and dry film methods. In particular, the critical parameters such as thickness, conductivity and mechanical property are discussed in detail. Finally, the future development directions of the solid electrolyte membranes are proposed.
