Title:
空気二次電池
Document Type and Number:
Japanese Patent JP5062322
Kind Code:
B2
Abstract:
A main objective of the present invention is to provide an air secondary battery which can suppress the deterioration in charge-discharge properties caused by the oxygen generated in an air cathode layer at the time of charge. The present invention solves the problems by providing an air secondary battery which comprises: an air cathode which has an air cathode layer containing a conductive material and an air cathode current collector which collects current of the air cathode layer; an anode which has an anode layer containing an anode active material and an anode current collector which collects current of the anode layer; and a permeation preventing layer which is formed on the surface of the side of the anode layer of the air cathode layer, made of a nonaqueous polymer electrolyte, and which prevents the permeation of the oxygen generated in the air cathode layer at the time of charge.
