Efficient Recycling of Spent LiCoO₂ Cathodes Via Confined Pore‐Assisted Simplified Direct Carbothermic Reduction Without External Reducing Agents

Energy & environment materials, Год журнала: 2025, Номер unknown

Опубликована: Май 20, 2025

As demand for lithium‐ion batteries increases, the supply of materials is increasingly constrained by their geographical concentration. This has spurred significant research into recycling spent to enhance resource circulation. Currently, commercially applied methods (such as pyrometallurgy and hydrometallurgy) face environmental economic challenges, including waste acid gas generation, high‐temperature heat treatment, operational complexity. A promising alternative carbothermic reduction process, which operates at lower temperatures, minimizing costs emissions. However, this method still requires large quantities external reducing agents. Therefore, study aims introduce a simplified direct (SDCR) process. The SDCR process leveraged carbon conductive organic binders within electrode Additionally, high compaction state created conducive environment gases, promoting efficient material recovery. approach reduces reliance on agents streamlines re‐upcycling making it viable.

Abstract Sustainable recycling of lithium‐ion batteries (LIBs) is essential for resource conservation and supporting the development renewable energy. However, conventional approaches face significant challenges due to mismatch between limited energy density regenerated increasing demand high‐performance LIBs, necessitating a shift toward upcycling strategies. Herein, an innovative strategy demonstrated that transforms mixed spent LiFePO 4 (LFP) LiMn 2 O cathodes into cathode materials. Through advanced methodologies reaction pathway control rational design metal coordination complexes, are recovered converted solid solution characterized by homogeneously distributed manganese iron elements. The 0.6 Fe 0.4 PO material, fabricated using this as precursor, delivers remarkable discharge capacity 160.7 mA g −1 at 0.2C retains impressive 93.1% retention after 500 cycles 1C. (3.85 V vs Li + /Li 558.9 Wh kg ) achieves voltage increase 0.49 19.7% enhancement in compared commercial LFP (3.36 466.8 ). This offers sustainable both production high
