Development Status of Lithium Batteries in China
After decades of development and innovation, Chinese lithium battery industry has made great breakthroughs in both quantity and quality. In 2021, Chinese lithium battery output reach 229GW, and it will reach 610GW in 2025, with a compound annual growth rate of more than 25%.
Through market analysis in recent years, the main features are as follows:
(1) The market scale continued to grow. From 2015 to 2020, the scale of China's lithium-ion battery market continued to grow, from 98.5 billion yuan to 198 billion yuan, and to 312.6 billion yuan in 2021.
(2) Power batteries account for a large proportion and grow faster. The rapid growth of new energy vehicles has driven the continuous growth of power batteries. In 2021, the output of consumption, power and energy storage lithium batteries will be 72GWh, 220GWh and 32GWh respectively, up 18%, 165% and 146% year-on-year respectively, accounting for 22.22%, 67.9% and 9.88% respectively. fastest growing. Among the power batteries, lithium iron phosphate batteries account for a high proportion. In 2021, the total output of lithium iron phosphate batteries is 125.4GWh, accounting for 57.1% of the total output, with a cumulative increase of 262.9% year-on-year.
(3) The square battery gradually occupies the dominant position. The prismatic battery is the most cost-effective, and has now occupied the mainstream of the Chinese market. In 2021, the market share of the prismatic lithium battery will be about 80.8%. Soft-pack battery cells have the highest energy density, but because the aluminum-plastic film is easily damaged, the battery pack needs to be equipped with more protective layers, resulting in a lack of overall energy density. About 9.5%. The round battery has the lowest cost, but the energy density is low. Fewer companies choose this type of battery, so the market share is about 9.7%.
(4) The cost of upstream raw materials fluctuates greatly. Affected by multiple factors such as the industrial cycle, the epidemic, and international tensions, the cost of upstream raw materials for power batteries will continue to increase in 2022.
