Contemporary Amperex Technology Co. Limited, abbreviated as 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).
CATL was founded in Ningde, which is reflected in its Chinese name ('Ningde era'). It is headquartered in Ningde, Fujian Province. In 2016, CATL was the world's third largest provider of EV, HEV and PHEV battery solutions behind Panasonic (Sanyo) and BYD. In 2017, CATL's sales of power battery system reached 11.84GWh, taking the sales championship worldwide for the first time.
As the Chinese government started to phase out subsidies for EVs towards 2020, CATL sought to diversify its revenue overseas. According to SNE Research, in the year of 2020, CATL's EV battery consumption volume ranks No.1 in the world for four consecutive years. In June 2020, CATL's founder Zeng Yuqun announced that the company had achieved a battery for electric vehicles rated as good for 1 million miles (or 2 million kilometers) and was waiting to receive orders.
CATL's battery technology is currently used by electric vehicle manufacturers in the international market, and CATL collaborates with companies including: PSA, Hyundai, Honda, BMW, Daimler AG, Tesla, Toyota, Volkswagen, and Volvo. In China, its clients include BAIC Motor, Geely Automobile, GAC Group, Yutong Bus, Zhongtong Bus, Xiamen King Long, SAIC Motor and Foton Motor.
According to former Tesla battery supply chain manager Vivas Kumar, CATL "are seen as the leaders of lithium iron phosphate battery technology". The company employs the cell-to-pack method to reduce the amount of inactive weight of its batteries. According to Kumar, unlike competitors such as LG Chem or SK Innovation, CATL is more willing to adapt outside technology, as opposed to applying a full in-house design.
In 2021 the company unveiled a sodium-ion battery for the automotive market. A battery recycling facility is planned to recover some of the materials.
