With the rapid increase in the proportion of ternary lithium-ion batteries, the demand for wet coated separators will greatly increase. However, due to high barriers in separator technology, slow expansion cycles, and slow release of effective production, high-end wet coated separators will be relatively scarce. Overall, with the rapid increase in sales of new energy vehicles and the continuous expansion of the rigid gap in power lithium-ion battery materials, China's lithium-ion battery materials have entered a golden period of development.

In terms of lithium-ion battery cathode materials, domestic companies are forming a trend of "coming from behind" in terms of technology and scale. The future development prospects are promising. In the past decade, large-scale lithium-ion battery cathode materials in China have rapidly developed, with significantly improved product quality and strong cost advantages. In recent years, Japanese and Korean lithium-ion companies have gradually started to import lithium-ion battery cathode materials from China, It is reported that the market share of lithium battery positive electrode materials in China has occupied about half of the global market, and there is still broad room for future development;

In terms of negative electrode materials, domestic companies have a comprehensive leading advantage, and their industry position has been formed, which is difficult to surpass in a short period of time; In terms of electrolytes, due to the control of patents and core additives by foreign companies, and the constraints of formulas on clients, domestic electrolyte manufacturers have actually become OEM factories;

In terms of separators, domestic companies have made slow technological progress and have not achieved breakthroughs in new systems, which have not fundamentally solved the problem. In order to improve the thermal stability and wettability of separators and electrolytes, domestic companies generally apply a layer of ceramic or organic coating on the separators, with a maximum of 5 layers. Although the performance will improve after coating, it also occupies battery space, Added lithium-ion battery weight.

In addition, although battery auxiliary materials are important, they have not been taken seriously by domestic companies, so auxiliary materials have long been monopolized by foreign companies and are also the most likely to get stuck.
