ELECTRODE AND ALL-SOLID STATE NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode in which an active material particle and a solid electrolyte particle come in contact with each other more sufficiently than before, and to provide an all-solid state nonaqueous electrolyte battery using the electrode.

SOLUTION: The electrode is provided with an active material layer which contains an active material powder formed of the active material particles and a solid electrolyte powder formed of the solid electrolyte particles. The active material particle (active material powder) is lithium titanate having a BET specific surface area of 1 m2/g or more but less than 10 m2/g. In addition, the solid electrolyte particle contained in the active material layer has an average particle diameter smaller than an average particle diameter of the active material particle. The electrode having such a structure is used as a positive electrode 1 or a negative electrode 2 in an all-solid state nonaqueous electrolyte battery 100.
