Abstract

The invention relates to a rechargeable metal-air battery with a bifunctional carbon catalysis material as an air electrode. The rechargeable metal-air battery adopts the bifunctional carbon catalysismaterial as the air electrode and tinsel as a negative electrode, and the loading capacity of the bifunctional carbon catalysis material is 1-7 mg/cm<2>. The bifunctional carbon catalysis material has efficient oxygen reduction and oxygen evolution electrochemical performances, has an excellent power generating performance and an excellent charge and discharge stability, and can be used in the field of zinc-air batteries, aluminum-air batteries, magnesium-air batteries and other rechargeable metal-air batteries as an excellent air electrode catalyst.

Description

technical field [0001] The invention belongs to the field of rechargeable metal-air batteries, in particular to a rechargeable metal-air battery using bifunctional carbon catalytic materials as air electrodes. Background technique [0002] The urgent need for energy and the enhancement of human environmental awareness have prompted countries all over the world to compete in the development and research of clean and sustainable energy conversion devices. Among them, devices that use electrochemical reactions for energy storage and conversion have attracted great attention [Nano Lett., 2012, December, 1946-1952]. Rechargeable metal-air batteries have been regarded as a promising new energy technology because of their high energy density, and are expected to be widely used in electric vehicles and other energy-consuming devices in the future [Adv.Energy Mater. , 2011, 1, 34-50]. As we all know, oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are the core r...
