What Battery Innovation Hub does

Battery Innovation Hub (株式会社BIH) is a Japanese battery technology startup founded in October 2019 as a spin-off from Yamagata University's Next Generation Battery Research Laboratory, headquartered within the university's Faculty of Engineering incubation facility in Yonezawa, Yamagata Prefecture. The company specializes in next-generation lithium-ion battery development with a core focus on semi-solid (gel electrolyte) batteries that replace combustible liquid electrolytes with non-flammable gel, delivering improved safety (eliminated leakage/fire risk), longer charge-discharge cycle life, and suppressed self-discharge compared with conventional liquid Li-ion cells. BIH also produces mass-production-ready liquid lithium-ion batteries in single-cell (3.7V 1500–2000mAh) and 2S pack (7.4V 1500mAh) configurations, targeting wearables, drones, and mobile devices.

The company's business model combines B2B contract services and limited product sales: (1) battery prototyping and performance evaluation services leveraging Yamagata University joint research and proprietary know-how on material combinations (cathode, anode, electrolyte, separator, binders, conductive aids, current collectors); (2) liquid lithium-ion battery product sales in standardized and customized sizes for wearables and drones; (3) battery development consulting covering design, material analysis, and process optimization; and (4) a smaller human resources development stream providing battery developer training, Japanese language education for foreign nationals, interpretation, translation, and website production. Pricing is custom quote-based; individual and small-lot sales are not accepted. Target customer segments are mobile battery/drone/wearable manufacturers (primary), automotive OEMs for hybrid vehicles via the Beijing Xingchuan partnership (primary, starting with the Chinese market), agricultural machinery and drone OEMs (via Go-Tech), and space applications (via JAXA). As of FY2025, the company has ~20 employees (including part-time), 60 million yen in registered capital, and is pre-Series A, with FY2026 targeted as the commercial productization milestone for hybrid-vehicle semi-solid batteries.
