Preparation and Electrochemical Properties of Pt–Ru/Mn3O4/C Bifunctional Catalysts for Lithium-Air Secondary Battery

摘要: Pt-based materials are generally recognized as promising electrocatalysts for use in Li-air batteries, but their high cost and scarcity present limiting factors for practical application. Therefore, catalyst costs need to be reduced by either replacing Pt with less expensive materials or by increasing the Pt dispersion. Herein, we report the fabrication of a Pt–Ru/Mn3O4/C composite as a relatively low cost and highly-efficient catalyst for use in Li-air battery cathodes. Mn3O4/C composites were first synthesized via simple precipitation …
