Title:
METHOD OF PREPARING ELECTROCATALYST
Document Type and Number:
WIPO Patent Application WO/2024/041644
Kind Code:
A1
Abstract:
Sustainable upcycling method of preparing an electrocatalyst, the method including: providing an electrode material obtained from a lithium-ion battery, wherein the electrode material includes LiFePO4@N-doped carbon core-shell particles; contacting the electrode material with an aqueous solution comprising an acid thereby forming the electrocatalyst; and optionally drying the electrocatalyst.
