Interfacial stability between sulfide solid electrolytes and lithium anodes: Challenges, strategies and perspectives

Optimization of Porous Structures of Carbon Matrices for Loading Red Phosphorus to Achieve High-Capacity and Long-Life Anodes for All-Solid-State Lithium-Ion Batteries

“…All-solid-state lithium-ion batteries (ASSLIBs) employing inorganic solid electrolytes (SEs) are acknowledged to enable a more stable (electro)­chemo-mechanical environment for those volume-changing electrode materials than liquid LIBs. − For instance, SEs cannot freely flow to wet the newly exposed electrode interfaces, which favors stable SEI formation. − Among all investigated SEs, sulfide electrolytes exhibit favorable mechanical ductility and the highest room-temperature ionic conductivity comparable to or exceeding liquid electrolytes. , Recent advances have witnessed excellent compatibility of alloy-type anodes with sulfide SEs. Some typical alloy anodes (e.g., Si, Al, or their lithiated forms) used in sulfide ASSLIBs have achieved far better long-term cycling stability than liquid LIBs. − Based on theoretical estimation, McDowell et al have identified that both gravimetric/volumetric energy densities of ASSLIBs with some alloy anodes are far beyond those of commercial graphite LIBs, even comparable to those evaluated of the Li-metal batteries using excess Li …”
