HELENA

The next generation in electric vehicle batteries will probably see the replacement of lithium-ion batteries with higher-performing alternatives. It is therefore crucial to develop different types of solid-state batteries to fulfil the growing energy density requirements. Generation 4b batteries have higher energy densities and longer ranges. The EU-funded HELENA project will respond to the need for a safe, high energy efficiency solid-state battery cell. Researchers are looking to produce a Generation 4b battery with a high-energy density lithium metal anode, a nickel-rich nickel–manganese–cobalt cathode and a superionic halide solid electrolyte. Project activities should enable low-cost, scalable and safe cell manufacturing and fast battery charging, thereby boosting the electric vehicles’ driving range.
