The amount of energy that a lithium-ion battery can supply to an electric vehicle (EV) is limited by the amount of charges stored in its anode and cathode materials. Although graphite has been the preferred anode material during the past 30 years, silicon oxide (SiOx) and silicon (Si) are two evolving anode materials capable of improving the energy density of EV batteries and extending the EV range by 20-40%. However, the higher-capacity gain of both silicon and silicon oxide is limited by the technical issue of large volume change-induced rapid capacity decay and processing difficulty.
