Sujeet Kumar
Sujeet Kumar is the co-founder and CEO of Ionblox, a Fremont, California battery company building pre-lithiated silicon-anode lithium-ion cells for electric vehicles and electric aviation. A materials scientist with a Ph.D. from the University of Rochester and more than 60 patents to his name, he previously served as CTO of Envia Systems, where his team developed one of the first 400 Wh/kg lithium-ion cells with a silicon anode. Ionblox, formerly Zenlabs Energy, has raised roughly $32 million in Series B funding from backers including Lilium, Applied Ventures, Temasek and Catalus Capital, and markets cells that promise higher energy density, up to five times more power, and 10-minute fast charging.
BANIQL
BANIQL is a Santa Clara / San Jose-based climate-tech startup building a low-acid, low-energy chemical process to extract nickel and cobalt from laterite ore for lithium-ion batteries. Its patented method runs at atmospheric pressure and lower temperatures, cutting energy use and CO2 emissions by roughly 80%, lowering costs by about 30% versus conventional high-pressure acid leaching (HPAL), and generating virtually zero waste. Founded in 2021, the company runs R&D and pilot production in the U.S. and ton-scale prototype production in Indonesia, targeting the EV and battery-materials supply chain.
