Safe and durable high-temperature lithium-sulfur batteries

27.06.2016 | Canadian Light Source | www.lightsource.ca

Safety has always been a major concern for electric vehicles, especially preventing fire and explosion incidents with the best possible battery technologies.

Lithium-sulfur batteries are considered as the most promising candidate for EVs due to their ultra-high energy density, which is over 5 times the capacity of standard commercial Li-ion batteries. However, batteries operating at the high temperatures necessary in electric vehicles presents a safety challenge, as fire and other incidents become more likely.

Lithium-sulfur battery has an improved safety

Team of researchers from Western Ontario, in collaboration with researchers from the Canadian Light Source, have developed safe and durable high-temperature Li-S batteries using by a new coating technique called molecular layer deposition (MLD) technology for the first time.

MLD is an ultrathin-film technique with applications in energy storage systems, providing precise and flexible control over film thickness and chemical composition of the target material at a molecular scale. The MLD alucone coated carbon-sulfur electrodes demonstrated very stable and improved performance at temperatures as high as 55oC, which will significantly prolong battery life for high-temperature Li-S batteries.
