Patent Specification: English / Chinese
Title of Patent:
Method of preparing an electrocatalyst
Providing methods for preparing electrocatalysts from electrode material obtained from e.g., depleted lithium-ion batteries
This invention upcycles end-of-life LiFePO4-based lithium-ion battery (LIB) cathode into a single-atom electrocatalyst for oxygen reduction reaction (ORR) using a simple partial etching strategy
The etching strategy breaks a long-standing stereotype by constructing atomic catalytic sites using a top-down approach
The resulting material exhibits excellent ORR activity/stability in an alkaline medium as demonstrated by the high Eonsetof 0.97 V and a slight current decline of 9.5% after 16 hours of testing
Potential Areas of Applications:
Ammonia Fuel Cells
Zinc-Air Batteries
Sustainable Energy Solutions
Proposed Schemes:
Preferential Licensing Scheme, and it is subject to discussion.
Schemes are subject to the business model and are open for discussion.
