Graphene Coating Addresses Safety Concern of Lithium-ion Batteries

摘要

Lithium batteries are revolutionizing the electric vehicles EV industry due to their superior storage capacity. A key problem often associated with these batteries is their tendency to catch fire due to rapid charging or discharging, or overheating. At high temperatures, the lithium cobalt oxide cathode of lithium batteries decompose and release oxygen. The presence of oxygen results in combustion on reacting with any flammable products leading to a fire. Suitable ways to suppress oxygen production and thereby prevent its reaction with any flammable products are being explored.
