Advanced BatteRy System and Integration for Generation-4 Solid State CElls

The global EV market is largely reliant on battery electric vehicles (BEVs) that employ lithium-ion (Li-ion) batteries, mostly based on liquid electrolytes. Due to extensive research and development of Li-ion, we are gradually reaching the maximum chemical potential of today’s electrode materials regarding Nickel-rich cathodes. Yet Li-ion based battery systems, based on liquid electrolytes, still face significant limitations, due to their chemistries, such as high flammability, potential safety risks, burning, and explosions, electrochemical instabilities, and low ion selectivity.
In this regard, promising solutions are emerging in the form of solid-state battery EV (SSBEV) technology. However, the inherent differences between SSBs and traditional Li-ion batteries such as fundamentally distinct operating temperatures, charging rates, form factor and cell safety characteristics introduce complexities in integrating them into existing BEV systems, necessitating a redesign of the several systems. To meet this need, ARISE will develop an advanced solid-state, fourth generation (Gen-4) Li-ion battery system that offers advanced high-performance features, based on a cell-to-chassis concept with expandable modules that is applicable to any next generation S SBEV.
ARISE will cover 3 different development paths: 1) a new city car chassis design utilizing SSBs that is expandable when needed, 2) a novel battery and pack level Thermal Management System compatible with SSBs, 3) Smart Battery Management System that controls battery expansion, fast charging, and safety
