· JVASP-62652· Li2B2S5

Li2B2S5 is a lithium borate sulfide ceramic compound that combines boron and sulfur anions with lithium cations, forming a mixed-anion ceramic structure. This material is primarily investigated in solid-state ionics and energy storage research, where lithium-conducting ceramics are sought for next-generation all-solid-state battery electrolytes and related electrochemical devices. Li2B2S5 represents an emerging class of lithium superionic conductors that may offer advantages over conventional oxide ceramics in terms of ionic mobility and compatibility with lithium metal anodes, though it remains largely in the research and development phase rather than established high-volume production.
