Biggest Lithium-ion Battery Manufacturers

HLC4850 lifepo4 battery

Since its birth in the early 1990s, the lithium battery industry has been around for about 30 years. This industry has grown from a monopoly in Japan to the hegemony of Japan and South Korea, and now China, Japan, and South Korea.

Today, the editor will give you an inventory of the five strongest lithium battery companies in the world. The first thing that pops out of everyone’s head is our CATL, so let me see where the Ningde CATL rank.

  • CATL
    Global market share: 27.87%

CATL is one of the first power battery manufacturers in China with international competitiveness, focusing on the research and development, production and sales of new energy vehicle power battery systems and energy storage systems.

According to the statistics of SNE Research, a South Korean research institution, despite the impact of the epidemic, the total installed capacity of global power batteries in electric vehicles will still increase in 2020, reaching 137GWh, a year-on-year increase of 17%. Among them, the Chinese power battery manufacturer CATL has an installed capacity of 34GWh, ranking first in the world in installed capacity for the fourth consecutive year.

From the perspective of the supply relationship of the leading power battery company CATL, CATL mainly cooperates with leading companies in various fields or cultivates its own quasi-foundry at the level of cooperation. In terms of supporting customers, it has established stable cooperative relations with domestic auto companies such as BAIC, Yutong, and SAIC, and fully bound domestic auto companies through joint ventures. Overseas, it has successively become suppliers to world-class car companies such as global auto giants Volkswagen, Daimler, Jaguar Land Rover, PSA Volvo and Toyota.

The biggest feature of the Ningde era is the ternary lithium battery (NCM) with higher battery life. Compared with the ternary lithium battery, the lithium iron phosphate battery is safer, but the TV capacity ceiling is low. The ternary lithium battery has high capacity, but low safety. CATL attaches great importance to R&D and has more than 3,300 R&D personnel, accounting for 23% of the total. In 2019, CATL invested nearly 3 billion yuan in R&D, and the base and share of The ratio is much higher than the domestic average, thus establishing its status as a giant in the lithium battery industry.

If South Korea’s LG has more comprehensive technical reserves and Japan’s Panasonic battery technology is more advanced, then the CATL era has both, with balanced performance.


Panasonic, a world-renowned Japanese multinational company and the only designated supplier of battery packs for Tesla’s Model S, has worked with Tesla to jointly develop a nickel-based lithium battery pack after long-term efforts. Released in October 2021, the 4680 battery, with a diameter of 46mm and a height of 80mm, can not only store more power, but also halve the production cost of the battery. Tesla hopes to increase production of 4680 cells by a factor of 100 by 2020.

In 1997, the world’s first hybrid car, the Toyota Prius, was equipped with square nickel-metal hydride batteries made by Panasonic. Later, due to Japan’s revitalization strategy, hydrogen energy was raised to the national policy level. Toyota gave up the pure electric direction, and Panasonic turned to start. Tailor-made pure electric solutions for Tesla.

  • LG Chem
    Global market share: 10.55%

LG Chem, a battery manufacturing and R&D enterprise of South Korea’s LG Group, is the only battery supplier for Model Y models made in China.

LG Chem is a major battery supplier in the European market and a major battery supplier for electric vehicles in the United States. Its products have been used in Renault Zoe, Porsche Taycan, Mercedes-Benz EQC and other models.

LG has a deep and broad layout in the field of electrochemistry. It is one of the first companies to enter the lithium battery industry. It has a deep understanding of soft pack and cylindrical technology and is generally considered to be the most potential power battery leader.

At the same time, it is reported that LG Chem plans to increase the company’s battery cathode production in South Korea to 130,000 tons/year, which is more than double the new target output compared to the current 40,000-ton/year production capacity. From the details of the report, it is speculated that the content of this expansion is mainly focused on the positive electrode of high-nickel batteries.

Today, LG Chem’s factory in Iksan, South Korea, has an annual production capacity of 5,000 tons, and the three factories in Cheongju have a combined production capacity of 35,000 tons. The fifth factory will start partial production this year, with an estimated production capacity of 30,000 tons per year. In addition, the company also plans to build two more new plants by the end of this year, with a combined capacity of 60,000 tons.

It is reported that after 2024, LG Chem plans to increase the global cathode production capacity to 230,000 tons to ensure 50% of its own total demand-last year, its subsidiary LG Energy Solutions used nearly 300,000 cathodes Ton. LG has also formulated a specific roadmap and strategic partnership plan to obtain more ternary precursors and nickel sulfate.

  • BYD
    Global market share: 9.52%

BYD was established in 1995. From 2000 to 2002, BYD became the first Chinese lithium-ion battery supplier for Motorola and Nokia. In 2002, the company was successfully listed on the main board of Hong Kong. In 2011, the company was listed on the Shenzhen Stock Exchange. “Blade battery”, a major breakthrough has been made in the field of battery research.

BYD is one of the earliest car companies in China to launch new energy vehicles. The company is headquartered in Shenzhen, Guangdong, China. It is a world-renowned high-tech private enterprise with three major industrial clusters of IT, automobiles and new energy.

BYD mainly produces two types of power batteries, one is ternary lithium battery (NCM battery) and the other is lithium iron phosphate battery. BYD has innovated the structure of lithium iron phosphate battery and launched a blade battery. The energy density of the same volume has been increased by 50%, which is close to the level of NCM battery. The cost has also been greatly reduced by 30%, and the safety has also been greatly improved. improve.

According to BYD’s company announcement, the company plans to have a total production capacity of 110Gwh by the end of 2021. According to the project statistics disclosed by the company, the cumulative production capacity of the currently disclosed power battery projects will reach 165Gwh. It is expected that after the project is completed, the company’s lithium battery production capacity will reach 265Gwh. In terms of lithium batteries, the company will continue to promote the application of new technologies, expand the customer base, and promote the continuous increase of market share in related fields.


Samsung SDI is a subsidiary of South Korea’s Samsung Group. It has more than 15 years of mass production experience in the field of lithium-ion batteries. Now it sells more than 1 billion batteries every year, forming a complete electric vehicle power supply from battery cells, modules to battery packs. battery business system.

Samsung SDI has established automotive power battery factories in Korea, China, the United States, Europe and other places. So far, it has been selected as the core battery supplier for more than 30 electric vehicles. It is the official strategic partner of BMW. Other core customers include Volkswagen, Mercedes-Benz, etc.

At present, Samsung SDI products have been applied to BMW i3, i8, Porsche Cayenne S, Audi e-tron and other models.

In fact, in addition to high-nickel batteries, Samsung SDI is also developing solid-state batteries. On May 25, Samsung SDI announced that it will develop large-scale all-solid-state battery cells and prototype all-solid-state battery cells by 2025, with mass production starting in 2027. At the same time, in terms of Toyota, Samsung is second only to Toyota in the number of international patents related to all-solid-state battery technology.
