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. However, the technology has several holdups, including losing energy as it stores and releases its charge.The reaction mechanisms are, in general, not well understood. 2017.40.

Jülich, ORNL researchers advance high energy density iron-air batteries

Green Car Congress

When it comes to volumetric energy density, iron–air batteries could perform even better with 9,700 Wh/l—almost five times higher than today’s lithium-ion batteries (2,000 Wh/l). The oxygen required for the reaction can be drawn from the surrounding air so that it does not need to be stored in the battery.
