Ningde Amperex Technology Limited

Ningde Amperex Technology Limited is a Chinese manufacturer of lithium-ion polymer batteries, founded in 2008 and based in Ningde, Fujian, PRC. It operates as a subsidiary of Amperex Technology Limited (ATL), which in turn is a wholly-owned subsidiary of the Japanese multinational electronics manufacturer TDK Corporation. The parent company, ATL, which is headquartered in Hong Kong, has approximately 2,001 to 5,000 employees and an estimated annual revenue of $100 million.

The company specializes in providing high-quality lithium batteries and services, with products categorized into high energy density, high power, fast-charging, arbitrary-shaped cells, and battery packs. These batteries are integral components in a wide range of consumer electronics, including smartphones, notebook PCs, tablets, power banks, micro mobile devices, drones, robots, smart wearables, and residential energy storage systems (RESS). Ningde Amperex Technology Limited is known for developing and manufacturing rechargeable lithium-ion batteries and leverages significant investments in research and development, holding numerous patents globally.

In terms of patent litigation, Ningde Amperex Technology Limited maintains a defensive posture. The company has been involved in one tracked case, appearing as a defendant and not as a plaintiff. This indicates it operates as an operating company that defends against patent challenges, rather than asserting patents as a non-practicing entity.

The sole tracked case involving Ningde Amperex Technology Limited is "ZHUHAI COSMX BATTERY CO., LTD. v. Ningde Amperex Technology Limited," initiated on April 1, 2025, at the Patent Trial and Appeal Board (PTAB). This proceeding typically involves challenges to the validity of existing patents, reflecting a dispute within the lithium-ion battery sector, where both Ningde Amperex Technology Limited and Zhuhai CosMX Battery Co., Ltd. are active players.
