Tenpower

What Tenpower does

Tenpower (Jiangsu Tenpower Lithium Co., Ltd.) is a Chinese manufacturer specializing in cylindrical lithium-ion battery cells in 18650, 21700, and 26700 form factors, serving tier-1 international OEMs across power tools, micro-mobility, smart appliances, and IoT/industrial applications. The company is a wholly-owned subsidiary of publicly listed Jiangsu Azure Corporation (002245.SZ, Shenzhen Stock Exchange) and operates four production bases — Zhangjiagang Plants 1 and 2, Huai'an Plant 3, and a new Selangor, Malaysia Plant 4 — with combined annual capacity exceeding 2 billion cells. Since 2006 the company has shipped more than 10 billion cells to hundreds of enterprises across 40+ countries and claims the #2 global market share in power tools lithium-ion cells.

The product portfolio spans three chemistries — NCM/NCA, LFP, and emerging sodium-ion — with the core differentiator being high-discharge-rate cells (up to 60A continuous in 21700 format), proprietary tabless cell architecture, and advanced materials including nickel-rich cathodes and silicon-based anodes delivering up to 600mAh/g electrode capacity. R&D is led by SVP Kiyokazu Oiyama (35+ years at Sony, involved in the original 18650 and Li-ion polymer R&D) and supported by academic partnerships with Fudan, Soochow, Shanghai Jiao Tong universities, and Chinese Academy of Sciences institutes. The business operates a B2B direct-sales model exclusively, with long-term strategic procurement agreements and exclusive supplier relationships (e.g., Einhell's Power X-Change platform since 2014) replacing conventional transactional pricing. Major customers include Bosch, Einhell, Stanley Black & Decker, Techtronic Industries (TTI), Metabo, Electrolux, Honda, and Super Soco (Xiaomi ecosystem). Manufacturing is augmented by patented efficiency systems — including 30% energy savings in dehumidification and 99.98% NMP recovery — that reinforce a structural cost advantage in cylindrical cell production.

Core offering

Tenpower designs, develops, and manufactures cylindrical lithium-ion battery cells in 18650, 21700, and 26700 formats across NCM/NCA, LFP, and sodium-ion chemistries, specializing in high-rate (up to 60A continuous discharge) and high-energy-density cells. The company sells direct B2B to tier-1 international OEMs in power tools, micro-mobility, smart appliances, and IoT sectors via four manufacturing plants with combined capacity of over 2 billion cells per year.

Product overview

Tenpower is a leading cylindrical lithium-ion battery cell developer and manufacturer specializing in 18650, 21700, and 26700 format cells. The product portfolio comprises three core battery chemistries: NCM/NCA (nickel-rich cathode with Si-based anodes for high power), LFP (LiFePO4 for long cycle life), and emerging sodium-ion technology. Cells are organized into performance tiers including Power (SG/XG/PG suffixes for 15A-60A continuous discharge), Energy (ME/HE suffixes for high capacity), and Cycle (LFP for longevity) categories. These cells are integrated into application-specific solutions for power tools (serving as exclusive supplier to Einhell's Power X-Change platform), smart appliances (cordless vacuums, cleaning robots), micro-mobility (e-bikes, e-motorcycles through partnerships with Honda and Super Soco), and IoT (drones, AGV, UPS). The company operates four manufacturing plants across China (Zhangjiagang Plants 1-2, Huai'an Plant 3) and Malaysia (Plant 4), with a combined global annual production capacity exceeding 2 billion cells.
