IM L6 – world’s first production car with a solid state battery

IM Motors claim that the L6, due to launch in May, will come with the industry’s first mass-produced ultra-fast charging solid state battery. More details will be announced at the IM L6 Technology Conference on April 8 but we already know that the new battery will be 130 kWh.

The cathode (positive electrode) is coated with ultra-high nickel material with the anode (negative) being a new generation of high-specific energy composite silicon carbon material. Where solid-state batteries differ significantly from existing technology is with the electrolyte being solid, in the case of the one used by the IM L6 a patented self-developed nano-scale electrolyte. This has “high ionic conductivity, high-temperature resistance” which presumably means the fire risk will be less. Furthermore, the electrolyte uses dry solid layer integrated molding with the resultant battery having reduced internal resistance meaning ultra-fast charging is possible. These technologies solve the problem of high expansion of silicon-based materials ensuring stability, and allowing better charging/discharging performance ultimately ensuring better safety. SAIC claim the car has quasi 900V ultra-fast charging.
