What's the endgame? The company is building lithium-ion cells it says can charge in 15 minutes and last twice as long as conventional batteries, at no higher cost. It completed product research and development in 2020; the remaining stages are pilot and then mass production.
Who's behind it? The Batteries was founded in 2017 by Oleg Tanasevich and Aleksey Starovoitov, alumni of car holding Atlant-M and founders of vacuum-equipment maker StratNanoTek Invest. It is a resident of the Podkarpackie Science & Technology Park Centre Aeropolis in Rzeszów, Poland.
