This translates to an energy enhancement ~4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO 2 (~600 W h kg electrode -1 , the researchers said. In that work, the carbon structures were more complex but only had about 70% void space. Energy Environ. ” Resources. Mitchell, Betar M.

Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. One reaction that hasn’t been fully explained is how oxygen blows bubbles inside a lithium-air battery when it discharges. The paper is published in the journal Nature Nanotechnology.

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. Li 2 O 2 precipitate passivates the electrode surface hindering further electron transfer.
