Understanding and designing polymeric interfaces in Li-ion and Li-air batteries

October 17 @ 10:30 am - 11:30 am

Lithium-ion batteries (LiB’s) have gained intensive research focus in recent years due their application in plug-in hybrid and complete electrical vehicles. Typical LiB’s operate using rocking chair mechanism by shuttling Li+ and electrons between negative and positive electrodes, which are separated by an electrolyte and a separator. The electrolyte undergoes chemical change during operation to form an interface between the electrode and electrolyte called the Solid Electrolyte Interface (SEI). The so formed SEI determines the cycling ability, rate performance and storage ability of the final LiB’s. Hence, in order to realise complete electric vehicles with excellent cyclability and superfast charging ability, it is essential to understand and enhance SEI characteristics. One strategy is to build artificial SEI’s which have required characteristic for superior performance. This talk will provide basic insight into chemistry of SEI and discuss some representative design strategies from a molecular point of view.
