UK Researchers Developing Rechargeable Lithium-Air Battery; Up to 10X the Capacity of Current Li-ion Cells

Green Car Congress

Diagram of the STAIR (St Andrews Air) cell. Oxygen drawn from the air reacts within the porous carbon to release the electrical charge in this lithium-air battery. Researchers in the UK are developing a rechargeable lithium-air battery that could deliver a ten-fold increase in energy capacity compared to that of currently available lithium-ion cells. Oxygen from the air is the active material for the cathode and is reduced at the cathode surface.

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. In his remarks made at Stanford University in November 2014 during the award of the third Science Award for Electrochemistry to Dr. Vanessa Wood, noted that he saw “ great potential ” in solid-state batteries.

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. One reaction that hasn’t been fully explained is how oxygen blows bubbles inside a lithium-air battery when it discharges.
