Lithium-air (or lithium-oxygen) batteries potentially could offer three times the gravimetric energy of current Li-ion batteries (3500 Wh/kg at the cell level); as such, they are looked to a potential solution for long-range EVs. One of the main problems related to Li 2 O 2 precipitation is its insulating nature.
