Abstract
Lithium-ion batteries lay the foundation for satisfying the fast-growing demand of portable electronics and electric vehicles. However, due to the complexity of material syntheses, high fabrication temperature condition, and toxic gas emission, high volume manufacturing of lithium-ion batteries is still challenging. Here, we propose a modified coprecipitation method to synthesize Li(1.0)Ni(0.6)Mn(0.2)Co(0.2)O(2) (NMC622-MCP) as a cathode material in a simple, cost-effective, and environmentally friendly approach. We demonstrate that the proposed method can be operated in a lower temperature environment, with respect to the requirement of conventional synthesis methods. Furthermore, only CO(2) gas is emitted during synthesis. We also employed first-principles simulations to evaluate the crystallinity of the synthesized materials via X-ray diffractometer patterns. During charge/discharge processes, the obtained cathode materials induce outstanding electrochemical performance with a maximum specific capacity of up to 206.9 mAh g(-1) at 0.05 C and a retention capacity of 83.22% after 100 cycles. Thus, the simple, cost-effective, environmentally friendly, and highly electrochemical performance of the newly acquired material envisages the modified coprecipitation method as a promising tool to manufacture cathode materials for lithium-ion batteries.
