With the continuous progress of technology, the development of positive electrode materials is mainly focused on improving energy density, improving safety performance and extending battery life. For example, high-nickel ternary cathode materials increase energy density by increasing nickel content while reducing cobalt content to reduce cost and environmental impact. However, this also leads to the deterioration of electrode structural stability and thermal stability, and the reduction of battery cycle stability. Further material innovations and process improvements are needed to ensure their safety and long-term reliability.

The innovation of cathode materials is crucial to the development of the lithium-ion battery industry, which is not only related to the improvement of battery performance, but also affects the market competitiveness and sustainable development of the entire industry. With the continuous emergence of new materials and new technologies, the performance of lithium-ion batteries will continue to be optimized and improved. The development of the lithium-ion battery industry has been driven by the dual advancement of material technology and patented technological innovation.

In recent years, with the rapid development of the new energy vehicle market, the demand for lithium-ion battery technology has entered a new peak, and major battery manufacturing enterprises have increased research and development investment, competing to take the lead in battery performance, safety, cost and patented technology.

Patent data show that patent activity for batteries and other power storage technologies grew at an average annual rate of 14 percent between 2005 and 2018, four times the average for all technology fields. This growth is mainly driven by advances in rechargeable lithium-ion battery technology, especially in consumer electronics and new energy vehicles.

The demand for electric mobility has prompted the development of high-performance lithium-ion technology aimed at improving battery energy density, service life, charging and discharging speed, and low temperature performance. In addition, in order to better integrate renewable energy sources such as wind and solar into the power network, it has also promoted the progress of energy storage battery technology.
