Title:
CATALYST FOR METAL-AIR CELL AND METAL-AIR CELL COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2015/053496
Kind Code:
A1
Abstract:
The present invention provides a catalyst for a metal-air cell having high electric conductivity and high activity. The catalyst for a metal-air cell according to one embodiment of the present invention comprises a LnETO5+δ compound, wherein E is one or more elements selected from an alkaline earth metal group, T is one or more elements selected from transition metals, O is oxygen, and δ is a positive number smaller than or equal to 1 and is a value satisfying electroneutrality in the LnETO5+δ compound.
