Beijing Weilan New Energy Technology

What Beijing Weilan New Energy Technology does

Beijing Weilan New Energy Technology (also branded as WELION or WeLion New Energy) is a Beijing-based, privately-held manufacturer of next-generation lithium batteries, founded in 2016 and operating with 1,001-5,000 employees. The company is focused on solid-state and semi-solid-state battery chemistries, which it positions as offering reduced fire risk and higher energy density compared with conventional lithium-ion technology. Its core product lines are solid-state lithium batteries (primary technology focus, targeting electric vehicle applications) and semi-solid-state batteries that incorporate BASF's ultra-high-nickel NCM cathode active materials with composite coating. The stated end-market applications span electric vehicles, stationary energy storage, unmanned aerial vehicles (drones), and cordless power tools.

The company monetizes primarily through B2B hardware sales, supplying cells directly to automotive OEMs and operating as a co-development partner rather than a transactional supplier. Named OEM customers include NIO and Geely, both positioned as core strategic partners for solid-state battery integration into EV platforms. Cathode active materials are sourced from BASF Battery Materials via the BASF Shanshan Battery Materials joint venture in China, with mass production of these materials achieved in September 2025 after roughly one year of project work. The company is single-country domiciled (China) with all disclosed operations in East Asia.

Capital structure reflects a venture-backed, pre-IPO company. Total disclosed funding exceeds $300M USD across multiple rounds (Series D of ~1.5 billion yuan / ~$208.8M USD in November 2022, plus earlier Series C, B, and seed rounds), with backing from state-owned investors including China Chengtong Mixed Reform Fund, CITIC Construction Investment, Beijing State-owned Capital Operations and Management, and the Beijing Green Energy and Low-Carbon Industry Investment Fund, as well as strategic investors that are also customers or ecosystem participants (NIO Capital, Geely, Xiaomi, Huawei). As of April 2026, the company had entered pre-listing tutoring for a Shenzhen Stock Exchange IPO.
