Graphene coating could help prevent lithium battery fires

Science Daily  April 9, 2019
A team of researchers in the US (University of Illinois, Texas A&M, Argonne National Laboratory) has shown that an atomically thin layer of reduced graphene oxide can suppress oxygen release from LixCoO2 particles and improve their structural stability. They showed that the reduction of Co species from the graphene‐coated samples is delayed when compared with bare cathodes, the rGO layers could suppress O2 formation more effectively due to the strong COcathode bond formation at the interface of rGO/LCO where low coordination oxygens exist. This investigation uncovers a reliable approach for hindering the oxygen release reaction and improving the thermal stability of battery cathodes…read more. TECHNICAL ARTICLE
