Battery company 24M
has announced that it has developed commercially viable Nickel Manganese Cobalt
(NMC) cells with an energy density above 250 Wh/kg. The company has also delivered
similar NMC cells with an energy density above 280 Wh/kg to an industrial
24M’s new NMC cells were built with the company’s SemiSolid
lithium-ion battery design, which it claims can improve battery performance
while reducing cost. 24M is hoping to achieve an energy density target of 350Wh/kg
by the end of 2019, with the ultimate goal to exceed 400 Wh/kg.
“…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,” said 24M CTO Naoki Ota.
