ELECTRODE MATERIAL, ALL-SOLID LITHIUM SECONDARY BATTERY, AND MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an all-solid lithium secondary battery whose internal resistance does not increase even when charging and discharging are repeated.SOLUTION: An electrode material for an all-solid lithium secondary battery including a positive electrode, a negative electrode, and a solid electrolyte layer positioned between the positive electrode and the negative electrode is characterized in that: it is obtained by subjecting a porous powder compact as a base material, which contains at least an active material and a solid electrolyte, to a plating treatment; and a metal coating is formed on the surface of the active material and the solid electrolyte.
