EU project HELENA (Halide solid-state batteries for Electric Vehicles and Aircrafts) aims to develop solid-state batteries for electric road vehicles and aeroplanes. The partners rely on novel technologies for most parts of the batteries. Specifically, HELENA solid-state batteries will utilise a high-capacity nickel-rich cathode (NMC), a high-energy Li-metal anode (LiM) and a halide electrolyte as […] More…
