Abstract
Method of forming lithium-containing electrolytes are provided using wet chemical synthesis. In some examples, the lithium containing electrolytes are composed of β-Li3PS4 or Li4P2S7. The solid electrolyte may be a core shell material. In one embodiment, the core shell material includes a core of lithium sulfide (Li2S), a first shell of β-Li3PS4 or Li4P2S7, and a second shell including one of β-Li3PS4 or Li4P2S7 and carbon. The lithium containing electrolytes may be incorporated into wet cell batteries or solid state batteries.
