24M delivers first industrial scale, excessive vitality density semi-solid NMC Li-ion cells; > 280 Wh/kg
24M introduced that it has developed and delivered commercially-viable, excessive vitality density lithium-ion cells. Utilizing its novel SemiSolid lithium-ion battery design in its pilot facility (earlier publish), 24M achieved vitality densities exceeding 250 watt-hours per kilogram (Wh/kg), the present state-of-the-art benchmark for EV purposes.
These deliveries symbolize a big milestone within the 24M mission to scale its distinctive, capital-efficient, low-cost method to superior lithium-ion battery manufacturing.
The event of the excessive vitality density nickel manganese cobalt (NMC) cells is a part of a $7-milion, three-year contract awarded to 24M in 2016 by america Superior Battery Consortium LLC in cooperation with the US Division of Power.
This system is chartered with growing electrochemical vitality storage applied sciences that help the commercialization of hybrid, plug-in hybrid, electrical and gas cell autos. To realize the ultimate USABC 2020 density goal of 350 Wh/kg by the tip of 2019, 24M has developed a multi-faceted, lab-proven method that features a novel use of silicon for prime vitality density anodes.
24M additionally delivered related NMC cells with vitality densities above 280 Wh/kg to an industrial accomplice. With these cells, the upper vitality densities have been achieved by optimizing 24M’s SemiSolid electrode know-how, which eliminates the usage of a pore-clogging binder, enabling greater lively materials densities than could be achieved with standard electrodes.
The demonstration of this know-how is a serious milestone on the 24M roadmap to attaining even greater vitality densities (>400 Wh/kg) utilizing its capital-efficient manufacturing course of.
24M launched its novel SemiSolid lithium-ion battery design in 2015, and has since leveraged its personal semi-automated pilot facility to considerably advance each cell design and manufacturing readiness.
The SemiSolid course of, which makes use of electrolyte because the processing solvent, eliminates capital and vitality intensive steps akin to drying, solvent restoration, calendaring and electrolyte filling.
It’s very gratifying to see science translated from the lab into progressive new merchandise as 24M has executed by growing and delivering these excessive vitality density cells. Furthermore, we have been capable of leverage our novel electrode, cell and manufacturing method to exceed 280 Wh/kg, a big step in the direction of delivering low-cost lithium-ion cells with industry-leading efficiency to the EV market.—Naoki Ota, CTO of 24M
