Because the financial system began to get well from the COVID pandemic, the value of Li2CO3 is skyrocketed to the best. This example has aggravated issues on the provision chain for lithium-ion batteries (LIBs). Recycling spent LIBs is a possible answer to alleviate the bottleneck of the provision chain and forestall environmental air pollution, which has attracted plenty of consideration. Though many researchers and producers have paid a lot consideration in the direction of the recycling technique of useful parts corresponding to Ni, Co, and Cu, lithium recycling is usually disregarded due to the complicated recycling course of and its low recycling effectivity. Right here, we developed a sustainable, extremely environment friendly, and selective recycling course of for lithium from spent LIBs. The leaching price of lithium is 100% on the optimized circumstances of 60°C for five hours for pure, blended cathode supplies and black mass from spent LIBs. After changing to Li2CO3 by easy distillation and post-sintering course of, the excellent recycling price of 99.8% with 99.994% purity might be achieved. To one of the best of our information, each the recycling charges and purity of lithium are the best amongst all reported works. Moreover, based mostly on value evaluation, a 11.15% expense discount might be achieved via this lithium restoration course of in contrast with typical hydrometallurgical course of.
