New, Highly Ion-Conductive Crystals Precipitated from Li2S-P2S5 Glasses

Novel sulfide lithium‐ion conducting materials are synthesized by crystallization of mechanically milled Li2S–P2S5 glasses. High ambient‐temperature conductivities (σ) compared with other electrolytes (see Figure) and a low conduction activation energy are achieved by the formation of a highly condu...

Description
Summary:Novel sulfide lithium‐ion conducting materials are synthesized by crystallization of mechanically milled Li2S–P2S5 glasses. High ambient‐temperature conductivities (σ) compared with other electrolytes (see Figure) and a low conduction activation energy are achieved by the formation of a highly conductive new crystalline phase.
