The attenuation of electrical power is mainly due to the change of the equivalent resistance of the battery, which is also caused by side reactions and the rupture of the electrode structure, And the common manifestation is the generation of a solid electrolyte interface (SEI) film on the electrode surface.
In recent years, the explosive development of NEVs has led to increasing demand for NEV batteries, which has led to the rapid development of the NEV battery industry, resulting in increasing prices of raw materials manufactured and sold by raw material manufacturers, i.e., the upstream battery industry.
During the application of lithium-ion batteries, inevitable aging issues arise with increasing charging-discharging cycles and calendar storage time.
Therefore, the development of high-energy and long-life batteries still faces certain challenges. In the following, we summarize the degradation mechanism analysis methods and explain the degradation mechanisms of various anodes and cathodes from the perspectives of chemical stability and mechanical stability.
As one of the core technologies of NEVs, power battery accounts for over 30% of the cost of NEVs, directly determines the development level and direction of NEVs. In 2020, the installed capacity of NEV batteries in China reached 63.3 GWh, and the market size reached 61.184 billion RMB, gaining support from many governments.
On the other hand, it is possible to reduce the production cost of batteries by giving some tax incentives to battery manufacturers or manufacturers of core components of the battery industry based on overall considerations of their production quality, sales performance, innovation ability, customer satisfaction, and other aspects.
