Semi-solid lithium ion cells start commercial tests

October 14, 2016 // By Nick Flaherty
US startup 24M has started delivering production-size battery cells using semi-solid lithium ion technology to NEC Energy Solutions for testing and evaluation.

Unlike traditional lithium-ion batteries, the 24M battery cells are optimized to withstand the rigors of the long cycle and calendar life required by grid-scale energy storage and other high-performance applications. In addition, the new 24M cell design enables innovations in manufacturing that cut today’s lithium-ion battery costs by up to 50%.

“This is a significant milestone for 24M, and meeting the deadlines set forth in the memorandum of understanding [in Octoner 2015] reflects our commitment to a productive partnership with NEC Energy Solutions,” said Chris Campbell, chief marketing officer at 24M. “We look forward to working with the NEC ES team through this testing and validation phase as we also prepare the next delivery milestone in early 2017.”

“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.”

The semi-solid cells reduce the amount of solvent in the battery, alllowing thicker layers and cutting drying time by 80% to make it cheaper to produce large batteries.
