A solid-state silicon battery or silicon-anode all-solid-state battery is a type of rechargeable lithium-ion battery consisting of a solid electrolyte, solid cathode, and silicon-based solid anode. In solid-state silicon batteries, lithium ions travel through a solid electrolyte from a positive cathode to a negative silicon anode.
But, in a solid state battery, the ions on the surface of the silicon are constricted and undergo the dynamic process of lithiation to form lithium metal plating around the core of silicon. “In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle,” said Li.
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.
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.
Lithium–silicon batteries are lithium-ion batteries that employ a silicon -based anode, and lithium ions as the charge carriers. Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon.
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 .
