Geochemistry‐Driven Recovery of Li and Fe From Spent LiFePO4 Cathodes via Stabilized Phosphorus Mineralization

open access: yesEcoEnergy, EarlyView.
A geochemistry‐guided, acid‐free recycling paradigm for spent LFP batteries. ABSTRACT The rapid expansion of lithium iron phosphate (LFP) batteries presents a critical challenge for sustainable end‐of‐life management, where conventional recycling methods heavily depend on intensive acid/oxidant use and overlook persistent phosphorus pollution.

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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.
