Title:
LITHIUM-AIR BATTERY AND LITHIUM-AIR BATTERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/067592
Kind Code:
A1
Abstract:
This lithium-air battery (2) comprises: a negative electrode (4) comprising a negative electrode material (40) that is capable of absorbing and desorbing lithium ions; a positive electrode (3) which uses oxygen as a positive electrode active material and comprises a positive electrode material that is provided with a catalyst (31) for reducing oxygen; and a solid electrolyte layer (5) which is interposed between the negative electrode and the positive electrode and contains a solid electrolyte. At least one of charging and discharging is carried out in the presence of water in a gas phase. Namely, reduction of oxygen or an oxide is carried out in the presence of water in a gas phase. Due to this configuration, this air battery exhibits an effect of reducing the overvoltage.
