Synthesis of cathode material with different dosage of maleic acid-leachate of spent lithium-ion batteries

In this paper, LiNi1/3Co1/3Mn1/3O2 cathode materials were synthesized by sol-gel with different dosage of maleic acid-leachate of spent lithium ion batteries (LIBs). Electrochemical performance test was performed on the re-synthesised materials to explore the effect of leachate dosage. The results show that the degree of Li+/Ni2+ mixing increased while initial discharge capacities and capacity retention decreased significantly with leachate dosage increasing. Therefore, the leachate dosage is preferably 65% which can achieve a win-win situation in economy and performance when the LiNi1/3Co1/3Mn1/3O2 cathode materials were synthesized with maleic acid-leachate of spent LIBs in our work.
