Summary: This research proposes a new, sustainable, and easy-to-implement process for the recycling of spent LiFePO4 cathode powder. The 732 cation exchange resin is used as a leaching agent and an adsorbent to recover Li and Fe from the waste powder. The results show that it is technically and economically feasible to use the 732 cation exchange resin for recovery, and high-purity products can be obtained.

Summary: A catalytic strategy is proposed to accelerate the reversible conversion of sulfur and discharge products in Li-S batteries using single-atom iron on nitrogen- and sulfur-doped porous carbon. The synergy between atomically dispersed iron and doped sulfur accelerates the reversible electrochemical conversion reactions in Li-S batteries, leading to superior long-term cycling stability. This study demonstrates a novel method for improving the conversion of polysulfides based on electrocatalysis strategies to ultimately obtain high-performance Li-S batteries.
