How to assemble high-energy all-solid-state lithium-sulfur batteries?

by:CTECHi     2021-07-04

All solid-state lithium batteries (ASSLB) use non-flammable inorganic solid electrolytes to significantly improve the safety and energy density of today’s lithium-ion batteries. Solid electrolytes play a key role in ASSLB.

Because of its excellent ionic conductivity and mechanical properties, sulfide-based solid electrolytes are one of the most promising electrolytes. The ionic conductivity of several sulfide electrolytes is comparable to that of organic The ionic conductivity of the liquid electrolyte is comparable or even higher, so that the all-solid-state lithium-ion battery has very high cycle and rate performance.

However, very thick solid electrolytes (~0.5-1.0mm) are usually used in these ASSLBs, so that the battery-level energy density of these ASSLBs is still limited
