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. The paper is published in the journal Nature Nanotechnology.

Researchers show feasibility of lithium-metal-free anode for Li-air battery; addressing one of three main barriers to Li-air battery development

Green Car Congress

Researchers from University of Rome Sapienza (Italy), Hanyang University (Korea) and the Argonne National Laboratory (US) have shown that the highly reactive lithium metal anode typically projected for use in Li-air batteries can be replaced with a lithiated silicon-carbon anode. Cycling current: 200 mA g ?1

3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

One negative side effect of a lean burn engine, whether powered by gasoline or diesel fuel, is an increase in the amount of emissions released to the environment. In 2007, Vorbeck signed a worldwide license agreement with Princeton University for a patented method from the the Aksay Labs for manufacturing graphene at commercial scale.

BMW researchers and colleagues in project ABILE develop optimized ionic-liquid-based electrolyte for efficient Li-air batteries

Green Car Congress

The study was financially supported by BMW within the project ABILE (Air Batteries with Ionic Liquid Electrolytes). However, the low energy efficiency and severe safety concerns associated with the reactivity of the lithium metal anode remain still unsolved and prevent the practical application of the lithium-oxygen battery technology.
