New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1

U-M team uses new technique to provide in-depth understanding of dendrite growth on Li metal anodes

Green Car Congress

Lithium-sulfur and lithium air batteries have the potential to store 10 times more energy in the same space as the current state-of-the-art lithium-ion batteries. However, the Li-metal electrodes in these next-generation batteries are especially prone to forming dendrites. Click to enlarge.
