Abstract
Abstract Among direct recycling methods for spent lithium‐ion batteries, solid‐state regeneration is the route with minimal bottlenecks for industrial application and is highly compatible with the current industrial cathode materials production processes. However, surface structure degradation and interfacial impurities of spent cathodes significantly hinder Li + replenishment during restoration. Herein, we propose a unique advanced oxidation strategy that leverages the inherent catalytic activity of spent layered cathode materials to address these challenges. This strategy decomposes H 2 O 2 to generate •OH and •O 2 − free radicals, facilitating oxidation reactions with the surface of the spent cathode. As a…
