Title:
CONDUCTIVITY AID FOR OXYGEN GENERATING ELECTRODE, AND UTILIZATION OF SAME
Document Type and Number:
WIPO Patent Application WO/2019/039538
Kind Code:
A1
Abstract:
The present invention relates to: a loop edge-pCNF containing conductivity aid for an oxygen generating electrode, in which conductivity aid at least a part of the edge of a carbon hexagonal net plane exposed on a side surface of the fiber of a carbon nanofiber (platelet carbon nanofiber, pCNF) having a platelet structure of carbon hexagonal net planes forms a loop structure with the edge of a proximate carbon hexagonal net plane; an ink for fabricating an oxygen generating electrode which contains the conductivity aid, an OER catalyst, and an organic solvent, and which may further contain an ORR catalyst; and a reversible air electrode which contains the conductivity aid, an ORR catalyst, and an OER catalyst. The conductivity aid of the present invention is a conductivity aid made of a carbon material that contributes to the improvement of the durability of an oxygen electrode for zinc air battery and that is resistant to oxidative consumption. It is possible to provide an oxygen electrode for zinc air battery in which the conductivity aid is utilized.
