With the increasing use of LiFePO4 (LFP) batteries, recycling spent LFP cathode materials in a green, efficient and economical way becomes essential. This study proposes a hydrothermal method directly regenerating spent LFP using low-cost Na2SO3 as a reductant, with Li2SO4 solution as the lithium so...
