The potential is for 400 Wh/kg
24M, the battery start-up headquartered in Cambridge, Mass., introduced first supply of a commercially viable, excessive power density lithium-ion cells – the SemiSolid lithium-ion battery design – to an undisclosed industrial companion.
The power density of the cells produced on the pilot facility exceed 280 Wh/kg, which – as 24M factors out – is over 10% greater than the present state-of-the-art benchmark for EV functions – 250 Wh/kg.
“These deliveries signify a major milestone within the 24M mission to scale its distinctive, capital-efficient, low-cost method to superior lithium-ion battery manufacturing.”
The 12% improve is welcome, though 24M’s objective is way increased – 350 Wh/kg and even over 400 Wh/kg. We guess that these targets should not but out there and improvement must be continued.
“The event of the excessive power density nickel manganese cobalt (NMC) cells is a part of a $7M three-year contract awarded to 24M in 2016 by the US Superior Battery Consortium LLC in cooperation with the U.S. Division of Vitality. This system is chartered with creating electrochemical power storage applied sciences that help the commercialization of hybrid, plug-in hybrid, electrical and gas cell automobiles. 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 top power density anodes.24M additionally delivered related NMC cells with power densities above 280 Wh/kg to an industrial companion. With these cells, the upper power densities have been achieved by optimizing 24M’s SemiSolid electrode expertise, which eliminates the usage of a pore-clogging binder, enabling increased energetic materials densities than might be achieved with standard electrodes. The demonstration of this expertise is a serious milestone on the 24M roadmap to reaching even increased power densities (>400 Wh/kg) utilizing its capital-efficient manufacturing course of.”
Naoki Ota, CTO of 24M mentioned:
“It’s very gratifying to see science translated from the lab into progressive new merchandise as 24M has achieved by creating and delivering these excessive power density cells. Furthermore, we have been in a position to leverage our novel electrode, cell and manufacturing method to exceed 280 Wh/kg, a major step in direction of delivering low-cost lithium-ion cells with industry-leading efficiency to the EV market.”
