Lithium ion batteries,as an important energy storage device,had broad application prospects.The positive electrode material was a crucial component in lithium-ion batteries,and its performance directly affects the working performance of the battery.In this paper,the effects of different raw materials on the performance of cathode materials for lithium batteries were studied,and new cathode materials for lithium batteries were prepared by sol-gel method.The experimental results showed that by adjusting the raw material ratio,the energy density,cycle life,and rate performance of the positive electrode material can be optimized.The high energy density ratio scheme improves the energy density of the battery,but the cycle life was relatively short,while the balanced performance ratio scheme achieves a better balance between energy density,cycle life,and rate performance.At the same time,this article explores the potential and prospects of optimizing the design of new lithium battery cathode materials,including improving energy density,enhancing cycle life,and improving safety.Through innovative material design and preparation processes,cross-border cooperation and technology integration,as well as emphasizing sustainability and environmental protection,it was expected to promote the development of new lithium battery cathode materials and meet the demand for high-performance lithium batteries in fields such as electric vehicles and mobile devices.
