PNNL team uncovers reaction mechanisms of Li-air batteries; how batteries blow bubbles

Green Car Congress

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. Oxygen gas is released and inflates the bubble.
