A patent entitled “Large-format battery anodes comprising silicon particles” was transferred from Colorado-based startup SiLion to Tesla in October 2021 and hints at the utilization of a conductive polymer coating to stabilize the silicon . Figure 1. The major IP players in different segments of batteries with silicon-based anodes .
Despite its long history in development, silicon, the second most abundant element on earth, has only recently started gaining traction in the battery industry as an anode material.
Silicon promises longer-range, faster-charging and more-affordable EVs than those whose batteries feature today’s graphite anodes. It not only soaks up more lithium ions, it also shuttles them across the battery’s membrane faster. And as the most abundant metal in Earth’s crust, it should be cheaper and less susceptible to supply-chain issues.
Anode materials for Li-ion batteries (LIBs) utilized in electric vehicles, portable electronics, and other devices are mainly graphite (Gr) and its derivatives. However, the limited energy density of Gr-based anodes promotes the exploration of alternative anode materials such as silicon (Si)-based materials
Additionally, researchers are actively exploring a range of novel materials, including silicon (Si), tin oxide (SnO₂), iron oxide (Fe₂O₃), copper oxide (CuO), and cobalt oxide (Co₃O₄), which are being specifically developed as potential anode materials for lithium-ion batteries with high energy density. , , , , .
Silicon-based anodes that can drop into li-ion chemistry to create lithium-silicon batteries will help to break through these hurdles and unlock an electrified future with longer lasting, better performing electronics, electric transportation, electric flight, space travel, and much more.
