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. —Luo et al.

Report: VW Group to decide how to proceed with Quantumscape solid state energy storage by July

Green Car Congress

The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. The all solid-state system would enable high energy density, high power density, and reversibility of a lithium-air battery, according to the claims. Earlier post.).
