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 partner. 24M’s new NMC cells were built with the company’s SemiSolid lithium-ion battery design,… Read more »
Cambridge, Massachusetts-based 24M has raised $21.8 million in Series D funding, which it will use to accelerate production of its SemiSolid lithium-ion cells for the EV market. Ceramics manufacturer Kyocera and global trading firm Itochu led the financing round. Previous investors, including North Bridge Venture Partners, also participated. 24M introduced its SemiSolid battery design in… Read more »
Massachusetts startup 24M has delivered an initial quantity of production-size battery cells to NEC Energy Solutions (NEC ES). 24M claims its semisolid lithium-ion cells, which have a mixture of solid and liquid phases, will be able to deliver up to a 50% cost reduction compared to current Li-ion designs. The 24M cells are designed to… Read more »
The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) has awarded $3.5 million in funding to a team that includes 24M, Sepion Technologies, Berkeley Lab, and Carnegie Mellon University. The funds will be used to develop novel membranes and lithium-metal anodes for a new generation of high-energy-density batteries. 24M’s core technology is semi-solid lithium-ion, a new class… Read more »
Startup 24M has emerged from stealth mode to introduce its semisolid lithium-ion cell, which the company claims will deliver improved performance at half the cost of current Li-ion batteries. “The lithium-ion battery is a brilliant, enabling technology, but its economics are flawed. It’s prohibitively expensive; it’s cumbersome and inefficient to make; and today’s version is… Read more »
