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 stand up to the long cycle and calendar life required by grid-scale energy storage applications. NEC ES will use them in its integrated storage systems.

“The market for energy storage solutions is growing rapidly, but cost remains a significant factor for many customers,” said Bud Collins, CEO of NEC ES. “With 24M semisolid lithium-ion battery cells, NEC ES will be able to include better batteries for a better price in our next-generation energy storage systems.”
