Method & Evidence

AimTo develop a self-powered electrocatalytic system that converts sulfion-containing wastewater into clean water and hydrogen, utilizing catalysts derived from spent lithium-ion batteries.

MethodExperimental research and system integration

ProcedureSpent lithium-ion batteries (specifically LiCoO2 and LiFePO4) were processed to extract materials for catalyst synthesis. Bifunctional catalysts (Co9S8 for sulfion oxidation and hydrogen evolution, and Fe-N-P codoped carbon nanotube arrays encapsulated Fe2P for oxygen reduction) were prepared. A sulfide fuel cell (SFC) was constructed using these catalysts to generate electricity. This SFC was then integrated with an electrocatalytic hydrogen production electrolyzer (ESHPE) that processed sulfion-containing wastewater. The performance of the integrated system, including hydrogen production rate and wastewater purification, was evaluated.
