METHOD FOR PRODUCING LITHIUM ION CONDUCTING GLASS CERAMICS

摘要

PROBLEM TO BE SOLVED: To provide a method for stably producing glass ceramics excellent in lithium ion conductivity with which desired lithium ion conducting crystals can deposit.SOLUTION: A production method of lithium ion conducting glass ceramics comprises: (1) a step of preparing glass powder containing P, Li, M and O (M=Al or Ga); (2) a step of preparing mixed powder by adding TiOcrystal powder to the glass powder; and (3) a step of heat-treating the mixed powder to deposit the lithium ion conducting crystal.
