SOLID ELECTROLYTE MATERIAL, ALL-SOLID-STATE BATTERY AND METHOD FOR PRODUCING SOLID ELECTROLYTE MATERIAL

摘要

The main purpose of the present invention is to provide a lithium-ion solid electrolyte material with high conductivity, having lithium (Li), boron (B) and a PO4 structure. The present invention solves the abovementioned problem by providing a solid electrolyte material having lithium, boron and a PO4 structure, said solid electrolyte material being characterized in that the size of crystallites is not more than 50 nm.
