Emphases are placed on the interfacial compatibility between electrolytes and cathodes, such as mechanical contacts and interface chemical stability, which are critical to the lifespan of high-voltage lithium batteries. Moreover, guidelines for the future development of high-voltage solid-state lithium batteries are also discussed.
Moving forward, the potential of polymer electrolytes in lithium batteries appears promising, but there exists considerable scope for enhancing the ionic conductivity of these electrolytes (Figure 18).
Gel polymer electrolytes (GPEs) synergizing the benefits of solid and liquid electrolytes are promising electrolyte candidates for future lithium metal batteries (LMBs). However, the poor performance of GPEs in subzero temperatures (particularly in extremely cold conditions) limits their practical applications.
