02 Chinese market: Lithium iron phosphate dominates, with fierce competition among second tier brands
According to data released by the China Automotive Power Battery Industry Innovation Alliance, from January to August, the cumulative installed capacity of power batteries in China was 417.9GWh, a year-on-year increase of 43.1%. A total of 51 power battery companies have achieved vehicle installation support, an increase of 3 compared to last year.
Looking at the Chinese market, from January to August 2025, the cumulative installed capacity of power batteries in China was 417.9GWh, a year-on-year increase of 43.1%. A total of 51 power battery companies have achieved vehicle installation support, an increase of 3 compared to last year, making market competition more intense.
From the perspective of battery technology, lithium iron phosphate batteries continue to maintain an absolute advantage. Data from January to April shows that the cumulative installed capacity of lithium iron phosphate batteries is 150.0 GWh, accounting for 81.4% of the total installed capacity, with a cumulative year-on-year increase of 88.0%; However, the cumulative installed capacity of ternary batteries is only 34.3GWh, accounting for 18.6% of the total installed capacity, a year-on-year decrease of 15.9%.
In the Chinese market ranking, CATL, BYD, and China Innovation Airlines maintain their top three positions. Guoxuan High tech and EVE Energy have swapped rankings, ranking 4th and 5th respectively; Xinwangda and Honeycomb Energy have swapped rankings, ranking 6th and 7th respectively.
The competition among second tier battery companies is intensifying, with companies such as Ruipu Lanjun, Zhengli New Energy, and Jidian New Energy fiercely vying for market share. Since February 2025, Far Eastern Lithium has been listed in the top 15 for five consecutive months.
03 Global Landscape: Romance of China, Japan, and South Korea, Chinese Enterprises Continuously Expand
In contrast to the rapid progress of Chinese companies, the market share of Japanese and Korean battery companies has generally declined. Three Korean power battery companies (LG New Energy SK On, Samsung SDI's total market share was only 16.8%, a year-on-year decrease of 3.8 percentage points.
LG New Energy maintained its third place globally with a loading capacity of 67.4GWh, a year-on-year increase of 13.3%, but its market share declined from 11.6% in the same period last year to 9.7%. Samsung SDI became the only company in the top ten with negative growth, with a loading volume of 20GWh, a year-on-year decrease of 9.1%, and a market share below 3%.
The installed capacity of Panasonic in Japan has rebounded to 25.8GWh, a year-on-year increase of 16%, with a market share of 3.7%, ranking sixth. Panasonic has recently restructured its supply chain to increase the proportion of local production in North America in response to US tariffs on Chinese made batteries and raw materials.
From the perspective of the global market landscape, the comprehensive competitive advantage of Chinese battery companies continues to amplify. In contrast, Japanese and Korean companies are facing the challenge of market share being squeezed.
04 Global layout of Chinese battery companies
The pace of overseas expansion of Chinese power battery companies has significantly accelerated. Taking BYD as an example, its batteries are not only used in its own new energy vehicles, but also gradually supplied to car companies such as Ideal, Xiaomi, NIO, and Toyota.
In terms of overseas market layout, Chinese companies are actively seizing opportunities and expanding into the overseas energy storage market. Taking Chile as an example, as a major lithium mining country, Chile has abundant solar and wind energy resources. After the large-scale construction of sustainable energy facilities, it has generated a huge demand for energy storage and consumption.
According to incomplete statistics, since 2024, a total of 11 companies including CATL, BYD, Tianhe Energy Storage, Huawei, Kelu Electronics, and Atlas have won 16.96GWh of energy storage orders in the Chilean market. In the first half of 2025 alone, China has won 9.6GWh of energy storage orders in the Chilean market, which is 2.5 times that of the US market.
Chinese power battery companies are upgrading from product output to technical standards and brand output, and globalization has entered a new stage. Some enterprises deepen their international layout and enhance their global competitiveness through localized production, technological cooperation, and other means.
05 Future Trends: Technological Innovation Driving Industry Change
The technological iteration in the power battery industry is accelerating, and technological innovation has become the key to enterprise competition. From a global trend perspective, battery companies are continuously innovating around high energy density, fast charging performance, safety, and cost optimization.
CATL has launched a series of innovative products this year, including the second-generation Shenxing Supercharging Battery, Snapdragon Dual Core Battery, Sodium New Battery, etc., with layouts in both passenger and commercial vehicle fields. The launch of these innovative products further consolidates its technological leadership position.
The supply chain layout is also undergoing profound changes. In response to the localization requirements of batteries in various countries, Chinese battery companies are strengthening their upstream resource layout and localized production capabilities. Panasonic's restructuring of its supply chain to increase the proportion of local production in North America is an example.
In the future, with the maturity and industrialization of new technologies such as solid-state batteries and sodium ion batteries, the market pattern of power batteries may face a reshuffle. Chinese companies are increasing their research and development investment to seize the commanding heights of next-generation battery technology.
Technological competition has replaced capacity competition and become the main theme of the industry. The global electric vehicle market is far from saturated, and with the popularity of new energy vehicles in emerging markets such as Southeast Asia and South America, the power battery industry will see even greater growth potential.
Facing the global market, Chinese battery companies need to continuously innovate in localized production, carbon footprint management, recycling, and other aspects in order to maintain a leading position in future green competition.
