Contemporary Amperex Technology Co., Limited, (CATL) is a Chinese battery manufacturer and technology company founded in 2011 that specializes in the manufacturing of lithium-ion batteries for electric vehicles and energy storage systems, as well as battery management systems (BMS).[3] CATL is the biggest EV and energy storage battery manufacturer in the world, with a global market share of around 37% and 36.8% in 2022 and 2023, respectively.[4][5][6] It is headquartered in Ningde, Fujian province, where it maintains its flagship manufacturing hub.[7]

History

CATL was founded in Ningde, which is reflected in its Chinese name (宁德时代 'Ningde era'). The company started as a spin-off of Amperex Technology Limited (ATL), a previous business founded by Robin Zeng in 1999. ATL initially manufactured batteries for portable devices based on licensed technology.[8] In 2005, ATL was acquired by Japan's TDK company, but Zeng continued as a manager for ATL.

While the Chinese government started subsidizing EVs in 2009, ATL had set up an R&D division for EV batteries.[8] In 2011,[9] A group of Chinese investors, led by Zeng and vice-chairman Huang Shilin, spun off the EV battery operations of ATL into the new company CATL after acquiring an 85% stake. Former parent TDK retained its 15% stake in CATL until 2015.[10] Zeng has applied management styles of TDK and Huawei to his company.[10]

2011–2021

Amid the rise of electric vehicles, CATL gradually became one of the leading battery providers in the world due to its early investments in EV battery technologies and government subsidization of the battery industry. In 2011, China required foreign automakers to transfer crucial technology to domestic companies in order to receive subsidies for electric vehicles. In 2012, CATL established cooperation with BMW Brilliance, its first main customer.[11][12][13] China's dominant position in the battery manufacturing supply chain, including the control over rare-earth materials, provided an ideal foundation for Chinese companies like CATL to decouple from the monopoly of Western technology. It started to provide components to the supply chains of European and American vehicle manufacturers amidst competition from Panasonic and LG Chem.[14]

Corporate affairs

The key trends for CATL are (as of the financial year ending 31 December):[46][47][48]

Facilities

CATL operates fifteen battery manufacturing plants worldwide, namely in:[49]

• Guiyang, China

• Jining, China

• Liyang, China

• Luoyang, China

• Ningde, China

• Nanhui New City, China

• Xiamen, China

• Xining, China

• Yibin, China

• Yichun, China

• Zhaoqing, China

Partnerships

Due to its main competitor BYD Company prioritizing battery supply to its own vehicles, CATL was able to capture partnerships with foreign automakers.[10] CATL's battery technology is currently used by electric vehicle manufacturers in the overseas market, and CATL collaborates with companies including BMW,[50] Daimler AG, Hyundai,[51] Honda,[52] Li Auto, NIO, PSA,[53]

Assessment

According to former Tesla battery supply chain manager Vivas Kumar in 2019, CATL "are seen as the leaders of lithium iron phosphate battery (LFP battery) technology". The company employs the cell-to-pack method to reduce the inactive weight of its batteries. It increases volume utilization rate by 15% to 20%, doubles the production efficiency and reduces the number of parts for a battery pack by 40%, while the energy density of a battery pack jumps from 140 to 150 Wh/Kg to 200 Wh/Kg.[64]

According to Kumar, unlike competitors such as LG Energy Solution or SK Innovation, CATL is more willing to adapt outside technology, as opposed to applying a full in-house design.[10]

In 2024, Tu Le of consultancy Sino Auto Insights claimed that the US was "years behind" China in batteries, and that "if the US is going to be competitive on the global stage with EVs, through 2030 they’re going to have to use Chinese batteries".[65]

Since 2022

In the first half, CATL ranked first in the world with a market share of 34 percent, according to SNE research.[23] CATL announced plans to establish a battery factory in Debrecen, Hungary.[24][25] Their Yibin manufacturing plant was certified as the world's first zero-carbon battery factory.[26]

In July 2022, Ford announced buying batteries from CATL for use in the Ford Mustang Mach-E and Ford F-150 Lightning models, which subsequently raised concerns with the United States House Select Committee on Strategic Competition between the United States and the Chinese Communist Party. In October, CATL expanded its deal with VinFast to provide a skateboard chassis and "enhance global footprint".

On 12 August 2022, CATL announced its second European battery plant in Hungary.[27]

In 2023, CATL received the equivalent of US$790 million in state subsidies.[28] The same year, CATL introduced its M3P battery, offering a 15% increase in energy density, reaching 210 Wh/kg. The battery replaces the iron in the lithium iron phosphate battery with a combination of magnesium, zinc, and aluminum.[29]

Later that year, the company announced its Shenxing LFP battery.[30] The cathode of Shenxing LFP is fully nano-crystallized, which accelerates ion movement and the response to charging signals. The anode's second-generation fast ion ring technology increases intercalation channels and shortens intercalation distance. Its superconducting electrolyte formula reduces viscosity and improves conductivity. A new separator film reduces resistance. At room temperature, Shenxing can charge from 0 to 80% in 10 minutes and in just 30 minutes at -10 °C, maintaining 0-100 kph at low temperatures. Safety is enhanced by using a safe coating for the electrolyte and the separator. A real-time fault testing system allows for safe and fast refueling.[30] Ford announced a 2,500 worker battery plant in Marshall, Michigan using CATL technology. The facility would be a Ford subsidiary. Producing the batteries domestically would enable Ford customers to access federal subsidies. The project was paused after lawmakers questioned the tax subsidies.[31][32]

In November 2023, CATL and Stellantis announced that they are considering the possibility of joint investment in the form of a joint venture with equivalent contributions.[33][34] On 7 December 2023, CATL and Hong Kong Science and Technology Parks Corporation (HKSTP) signed a memorandum of understanding to establish a CATL research center at the HKSTP with investment of over HKD 1.2 billion.

In 2023, the World Intellectual Property Organization (WIPO)’s Annual PCT Review ranked CATL's number of patent applications published under the PCT System as 8th in the world, with 1,799 patent applications being published during 2023.[35]

In April 2024, CATL announced Tener, a large scale stationary energy storage system. It is claimed to feature all-round safety, zero degradation over five-years and 6.25 MWh capacity per unit. It incorporates biomimetic SEI (solid electrolyte interphase) and self-assembled electrolyte technologies.[36]

In August 2024, American legislators Marco Rubio and John Moolenaar asked Defense Secretary Lloyd Austin to add CATL to a list of companies prohibited from receiving U.S. military contracts.[37]

As of September 2024, CATL is the top recipient of Chinese corporate subsidies, a position it has maintained since 2023.[38][39]

In December 2024, CATL announced to its suppliers that it is willing to provide them with financial support to speed up the technology innovation in battery materials and equipment.[40] On 12 December 2024, it was reported that CATL will collaborate with Stellantis in a joint-venture to build a large-scale lithium iron phosphate battery plant in Zaragoza, an investment worth €4.1 billion. This 50-50 partnership, is anticipated to commence battery production in 2026 and will have a capacity reaching 50 GWh.[41]

On 7 January 2025, the US Department of Defense added CATL and Tencent to its list of "Chinese military companies".[42]

On 11 February 2025, CATL filed for a secondary listing on the Hong Kong Stock Exchange, aiming to raise over $5 billion to fund international expansion plans including projects in Hungary, Spain, and Indonesia.[43][44] Cornerstone investors included Sinopec, the Kuwait Investment Authority, Hillhouse Investment, Oaktree Capital Management and an Agnelli family investment fund.[45]
