With high specific capacity and nominal voltage, low self-discharge, and low cost, layered LiNixMnCo1-x-yO2 (NMC) cathode has gained interest for second-generation lithium-ion batteries. Because the performance of lithium-ion batteries highly depends on the composition, crystallography, morphology, and other parameters during synthesis, interest in developing high-performance lithium-ion batteries has motivated researchers to develop novel synthesis methods to control these parameters. Although significant progress has been made in several synthesis methods such as sol-gel, hydrothermal, solid-state, emulsion, and wet chemical at lab scale, an industrially-viable synthesis approach is needed for cost-effective production of highly efficient NMC cathode materials. This paper summerise various synthesis methods investigated on lab and industrial scales for new and regenerated NMC cathode from end-of-life lithium-ion batteries and their effect on the battery performance. It is found that co-precipitation is the most commonly used method to produces NMC cathode, while spray pyrolysis is commonly used at the industrial scale.
