BMW researchers and colleagues in project ABILE develop optimized ionic-liquid-based electrolyte for efficient Li-air batteries

Green Car Congress

The study was financially supported by BMW within the project ABILE (Air Batteries with Ionic Liquid Electrolytes). However, the low energy efficiency and severe safety concerns associated with the reactivity of the lithium metal anode remain still unsolved and prevent the practical application of the lithium-oxygen battery technology.
