Sam Dai
Sam Dai is the co-founder and CEO of Enpower Greentech, a battery cell maker building semi-solid-state, lithium-metal, and silicon-rich cells. Trained as a physicist at Tsinghua and a materials scientist at UT Austin under Nobel laureate John B. Goodenough, he started the company in 2012 with fellow post-doc Che Yong. The company has shipped over 3 million solid-state cells, holds more than 100 patents, and runs facilities across the US, China, Japan, and Germany. Dai was selected for Unreasonable Impact Asia Pacific 2024.
Blue Current, Inc.
Blue Current is a Hayward, California solid-state battery developer building what it calls a 'silicon-first,' fully dry battery platform. Its Silicon Elastic Composite chemistry ties glass-ceramic electrolyte particles to silicon anode particles with compliant polymers, constraining silicon swelling so high-silicon cells can cycle stably at low pressure without flammable liquids or PFAS. Positioned as a safety-focused, B2B licensing and pilot-manufacturing company, Blue Current targets electric mobility, grid-scale storage, and consumer devices, and closed an $80M+ Series D extension led by Amazon in December 2025.
Enpower Greentech Inc.
Enpower Greentech is a battery maker building the next generation of lithium-metal and solid-state cells. Founded in 2012 by two post-docs from Nobel laureate John Goodenough's lab, the company designs semi-solid, quasi-solid, and all-solid-state batteries with energy densities pushing past 500 Wh/kg. Its cells power industrial drones, eVTOL aircraft, high-altitude pseudo-satellites, and electric vehicles, and it says it has shipped more than 3 million cells across its SWIFT, FLEET, and KOSMOS platforms from facilities in the US, China, Japan, and Germany.
