Title:
LITHIUM AIR BATTERY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/030332
Kind Code:
A1
Abstract:
The present invention relates to a lithium air battery and a method of manufacturing the same, wherein the lithium air battery uses oxygen as an anode active material and is formed by laminating carbon black secondary particles which are composed of carbon black primary particles and graphene, and wherein the lithium air battery comprises: an anode including macropores greater than 100 nm formed between the carbon black secondary particles; a cathode arranged opposite to the anode; and a separation membrane disposed between the anode and the cathode. The lithium air battery experiences an increase in discharge capacity in a discharge test and a decrease in overvoltage, and can be manufactured by a simple method.
