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

Green Car Congress

JULY 25, 2016

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

In contrast to standard Li-O 2 cells, which cycle via the formation of Li 2 O 2 , the Cambridge team used a reduced graphene oxide (rGO) electrode, the additive LiI (lithium iodide), and the solvent dimethoxyethane reversibly to form and remove crystalline LiOH with particle sizes larger than 15 micrometers during discharge and charge.
