In an EV battery, the anode is the electrode where lithium ions are stored when the battery is charged. It typically consists of graphite-based materials. Experts say that the anode’s material and design directly impact the EV’s performance and using a higher silicon content can improve that.

Silicon is a promising alternative because it can deliver better energy density and speed up charge and discharge cycles.

I wish the article went into more details on how replacing carbon with silicon can increase energy density. Seems counterintuitive to me, and I’d love to learn more.
