24M announced it has created NCM battery cells with higher than 280 Wh/kg energy densityIn an official press release from yesterday, 24M has announced that it has created and delivered lithium-ion battery cells with an energy density that exceeds 250 Wh/kg. This figure is currently the best energy density level achieved in batteries powering commercial electric vehicles. 24M has used its SemiSolid lithium-ion battery design in its pilot facility to create these nickel manganese cobalt (NMC) cells. Its new electrode technology eliminates the use of a pore-clogging binder, enabling higher active material densities. This work is part of a $7M three-year contract awarded to 24M in 2016 by the United States Advanced Battery Consortium LLC in cooperation with the U.S. Department of Energy.24M ultimate goal is to achieve the final USABC 2020 density target of 350 Wh/kg by the end of 2019. The company has already delivered similar NMC cells with energy density exceeding 280 Wh/kg to an industrial partner. "It's very gratifying to see science translated from the lab into innovative new products as 24M has done by developing and delivering these high energy density cells," said Naoki Ota, CTO of 24M. "Moreover, we were able to leverage our novel electrode, cell and manufacturing approach to exceed 280 Wh/kg, a significant step towards delivering low-cost lithium-ion cells with industry-leading performance to the EV market."Source
