Abstract
Li ion batteries (LIB) are ubiquitous in portable electronics, and are increasingly used in automotive applications. Improvements in stability and long-term capacity of LIBs are essential to satisfy fast growing demands in both sectors. The electrolyte mixture in a LIB is often modified to boost the long term stability of the solid electrolyte interphase (SEI) which forms particularly at the surface of the battery anode. Small quantities of additives are known to increase the stability and long-term cyclability of LIBs. Some of the most widely used additives are cyclic carbonates such as vinylene carbonate (VC) and vinyl ethylene carbonate (VEC). This class of additives contain unsaturated C-C bonds, which are believed to facilitate the formation of a more stable SEI.
