ELECTRODE STRUCTURE OF ALL-SOLID BATTERY

摘要

PROBLEM TO BE SOLVED: To provide: an electrode improved in structure for conduction of electrons and lithium ions; an all-solid battery which is enhanced in electrochemical property by such an electrode; and a manufacturing method thereof.SOLUTION: An electrode comprises: an electrode active material A subjected to ion conductive coating; and an electrode active material B subjected to electron conductive coating. The electrode is arranged so as to have: an electrode portion having an increased volume density of the electrode active material A near the interface with a solid electrolyte; and an electrode portion having an increased volume density of the electrode active material B near a collector. In this way, an electrode advantageous in both of electron conduction and lithium ion conduction is achieved.
