What DLG does
DLG (Shanghai DLG Power Battery Co., Ltd., 上海德朗能电池有限公司) is a privately held Chinese manufacturer of lithium-ion power batteries and battery modules founded in October 2001 and headquartered in Fengxian District, Shanghai, with approximately 2,000 employees and 2018 revenue of 1.4 billion RMB. The company produces 18650 cylindrical lithium-ion cells (with reported energy density of 300wh/kg and unit capacity of 3400mAh) using 811 ternary cathode materials with silicon-carbon composition, and assembles customized battery modules/packs ranging from 50Wh to over 2000Wh that integrate proprietary battery management systems (BMS), battery boxes, and brackets.
The company operates five wholly-owned production facilities across China — Shanghai (HQ), Shenzhen, Zhangjiagang, Ningbo Fenghua, and Shandong — with a combined plant footprint exceeding 90,000 sqm and daily cell output of 100,000 PCS at its Zhangjiagang and Shandong sites. Customers span electric vehicle OEMs (buses, passenger cars, logistics vehicles, sanitation vehicles), e-bike manufacturers (where DLG claims global technology leadership), consumer electronics companies, and energy storage system providers. The company exports to five continents and maintains international sales offices in Las Vegas, Netherlands, Seoul, Hong Kong, and Melbourne.
DLG generates revenue through direct B2B sales of hardware (cells and packs) on quote-based pricing, with international certifications (IATF16949, UL, CE, ISO9001/14001/50001) supporting its OEM supplier position. The company has received strategic investments from HNA Group (2013) and Shikong Investment (2015), holds 96+ patents (including 22 invention patents), and participates in the Ministry of Industry and Information Technology's Lithium Battery Industry Safety Standards Working Group. Its portfolio of sub-brands includes DLG, DLG Power, DLG Energy, Next Generation (次世代), and Delan (德朗).
