Today, 24M emerged from stealth mode to introduce the semisolid lithium-ion cell, a revolutionary technology that solves the grand challenge of energy storage by enabling a new, cost-effective class of the lithium-ion battery. 24M’s semisolid lithium-ion is the most significant advancement in lithium-ion technology in more than two decades and combines an overhaul in battery cell design with a series of manufacturing innovations that, when fully implemented, will slash today’s lithium-ion costs by 50% and improve the performance of lithium-ion batteries. The technology will accelerate the global adoption of affordable energy storage.
Until now, the energy storage field has had two options to try to drive down costs – build massive and complex factories to produce lithium-ion batteries in high volumes or pursue entirely new chemistries that may never move from the lab to the commercial floor. With the invention of the semisolid lithium-ion battery, 24M presents a third option – work with the world’s preferred energy storage chemistry and unlock new opportunities for cost reductions through new cell design and manufacturing innovations. 24M’s platform is the most significant advancement in lithium-ion technology since its debut more than 20 years ago.
Following in the footsteps of Tesla and Mercedes-Benz, Nissan is now set to become the latest automaker to offer battery packs for stationary energy storage. Although pricing information has yet to be provided, the Nissan product should be relatively affordable, as it will incorporate used batteries from Nissan Leaf electric cars.
Nissan designed the battery packs as part of the 4R Energy joint venture with Sumitomo Corp., and has partnered with commercial energy storage company Green Charge Networks to manufacture them. While Nissan is the source of the actual "second life" lithium-ion batteries that no longer meet the demands of automotive use, Green Charge is providing the power management software.
According to Nissan, this is the first time that used EV batteries have been commercially utilized for such an application. "A lithium-ion battery from a Nissan Leaf still holds a great deal of value as energy storage, even after it is removed from the vehicle, so Nissan expects to be able to reuse a majority of Leaf battery packs in non-automotive applications," says Brad Smith, director of Nissan's 4R Energy business in the US.

Ryan Wallace for The Science Times: Known as the "Powerwall", Tesla's newest invention is a thin, wall-mounted battery that is the size of a flat screen TV. And with this new battery home owners who have already invested in solar power will be able to entirely go off the grid, and even to sell their excess solar juice back to energy companies.
