1. Top 10 lithium battery separator factories in China in 2022
As we all know, a battery consists of anode, cathode, electrolyte and separator. Here is a detailed article for you to know more about lithium ion battery anode. You can click to have further understanding. The data shows that in 2021, the total shipment of lithium battery diaphragms in China will reach 7.9 billion square meters, with a compound growth rate of 54% in the past six years.
In 2021, the global diaphragm shipment will be 10.7 billion square meters, and Chinese market will account for 73.8% of the global market share, an increase of 15 pct compared to 2020.
The development trend of the diaphragm industry is:
- Wet diaphragm is the mainstream technology route, and dry single pull is mainly used in energy storage and low-end electric vehicles.
- The four major materials of diaphragm technology have the highest threshold, long production expansion cycle and the strongest profitability.
- The supply of lithium battery separator products will be tightly balanced in 2022.
