Abstract

The burgeoning use of lithium-ion batteries (LIBs) creates a growing challenge: spent battery management. Traditional hydrometallurgical recycling with coprecipitation generates massive Na2SO4 wastewater, posing a significant environmental burden. This work presents a novel, closed-loop recycling method for LIB cathode materials that merges electrolysis and hydrometallurgy. Using Na2SO4 electrolysis, we produced high-purity sulfuric acid and sodium hydroxide solutions, which served as the key reagents for leaching and resynthesizing waste cathodes. Optimized leaching conditions ensure near-complete recovery of valuable metals. Li2CO3 and a precursor (Ni0.8Co0.1Mn0.1(OH)2) are subsequently precipitated and regenerated into a new LiNi0.8Co0.1Mn0.1O2 cathode material, which demonstrates excellent electrochemical performance. The spent Na2SO4 solution undergoes a simple treatment before re-electrolysis, achieving a closed-loop system with minimal waste generation and reduced reliance on external reagents. Moreover, the acid-leaching carbon residue is repurposed as a bifunctional carbon-based catalyst for hydrogen peroxide production. This innovative approach offers both economic and environmental benefits, paving the way for sustainable LIBs recycling and a circular economy for battery materials.

锂离子电池阴极闭合回路:一种绿色电冶金回收方法
锂离子电池(lib)的迅速使用带来了一个日益严峻的挑战:废旧电池的管理。传统的共沉淀法湿法冶金回收产生了大量的Na2SO4废水,造成了严重的环境负担。本研究提出了一种新颖的锂离子电池正极材料闭环回收方法,该方法将电解和湿法冶金相结合。采用Na2SO4电解法制备高纯硫酸和氢氧化钠溶液,作为废阴极浸出和再合成的关键试剂。优化的浸出条件可确保几乎完全回收有价金属。Li2CO3与前驱体Ni0.8Co0.1Mn0.1(OH)2析出再生为新的LiNi0.8Co0.1Mn0.1O2正极材料,具有优异的电化学性能。废Na2SO4溶液在再电解前经过简单处理,实现了一个闭环系统,产生的废物最少,减少了对外部试剂的依赖。此外,酸浸碳渣被重新利用为双氧水生产的双功能碳基催化剂。这种创新的方法提供了经济和环境效益,为可持续的锂离子电池回收和电池材料的循环经济铺平了道路。
