SOLID STATE BATTERY Russian patent published in 2013 - IPC H01M4/58 

FIELD: electrical engineering.

SUBSTANCE: solid state battery consists of the layer (1) of active material of the positive electrode which includes active material (4) of the positive electrode; the layer (2) of active material of the negative electrode which includes active material of the negative electrode; and the layer (3) of solid-state electrolyte placed in-between the layer (1) of active material of the positive electrode and the layer (2) of active material of the negative electrode. Then the layer (1) of active material of the positive electrode or the layer (3) of solid-state electrolyte contains solid electrolytic material (5). Part (6) that suppresses the reaction is placed at interface surface between active material (4) of the positive electrode and solid electrolytic material (5). Part (6) that suppresses the reaction is a chemical compound consisting of a cationic part formed from metal-type element and polyanionic part formed from the central element which generates covalent links with oxygen-type elements.

EFFECT: battery having high energy density due to suppression of resistivity increase at interface surface between active material of the positive electrode and solid electrolytic material.
