Solid electrolytes, as the core of all-solid-state batteries (ASSBs), play a crucial role in determining kinetics ion transport and interface compatibility with cathodes anodes, which can be subdivided into catholytes, bulk anolytes based on their functional characteristics. Among various inorganic solid ductile distinguished from rigid oxide exhibit excellent properties even under cold pressing, thus holding greater promise for industrialization. However, challenge lies finding electrolyte that simultaneously serve catholyte, electrolyte, anolyte. Fortunately, due to immobility combining multiple types electrolytes allows leveraging respective advantages. In this review, we discuss five sulfides, halides, nitrides, antiperovskite-type, complex hydrides, challenges superiorities these are also addressed. The impact pressure ASSBs has been systematically discussed. Furthermore, suitability anolyte is discussed characteristics physicochemical properties. This discussion aims deepen our understanding enabling us harness advantages develop practical, high-performance ASSBs.

In traditional operations of all-solid-state lithium metal batteries (ASSLMBs), a small thin circular disk is employed as anode (LMA). However, ASSLMBs with circular-disk LMA often fail in <150 cycles low capacity retention. this work, we developed new ring-shaped to improve cyclability. Full cells consisting LMA, LiCoO2 cathode, and Li6PS5Cl electrolyte maintain good retention 83.65% at 0.3C after 300 cycles. Moreover, situ L-band electron paramagnetic resonance imaging (EPRI) showed that fewer Li dendrites are formed on LMA. This work highlights the importance design shape mitigate growth shows EPRI useful technique for ASSLMBs.
