24M hails semi-solid technology ‘milestone’

US-based 24M has reached a “significant milestone” towards scaling up development of its novel semi-solid lithium-ion technology.
The Massachusetts company said it has developed and delivered “commercially viable, high energy density lithium-ion cells with energy densities exceeding 250 watt-hours per kilogram (Wh/kg)”.
The development of the high energy density nickel manganese cobalt (NMC) cells is part of a US$7 million three-year contract awarded to 24M in 2016 by the United States Advanced Battery Consortium (USABC), in cooperation with the US Department of Energy.
