Hyundai joins push for solid-state batteriesby Justin King
The automaker\'s venture capital arm has invested in Massachusetts-based Ionic Materials.
Hyundai has joined other automakers in pushing for solid-state battery technology, promoted as a potential breakthrough for electric vehicles.
The automaker's venture capital arm has invested an undisclosed amount in Ionic Materials, a privately held Massachusetts-based startup developing a patented solid polymer material that could replace liquid electrolytes.
Ionic claims its "breakthrough polymer" is the first solid electrolyte to fully function at room temperature and be compatible with lithium- and alkaline-based batteries.
Solid-state batteries theoretically address several issues with current lithium-ion cells including safety, energy density and charge degradation.
Researchers and startup companies have been working on solid-state battery tech for many years. None have demonstrated a viable solution for production at scale, however.
