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.
Many of the biggest names in silicon battery technology and several emerging players were there to give their outlook on this lithium-ion battery anode material with capacity for exceptional energy storage. It is not difficult to see why there has been well over two decades of sustained interest in silicon as a lithium anode material.
Lithium thus wins in the case of a so-called “anodeless” battery with no excess lithium metal; however, silicon starts to take the edge if the cell is constructed with an actual lithium metal anode that exceeds the quantity of cyclable lithium. For a battery with 3–4 mAh/cm 2 areal capacity, this corresponds to just 15–20 µm of lithium.
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.
Silicon's large volume change (approximately 400% based on crystallographic densities) when lithium is inserted, along with high reactivity in the charged state, are obstacles to commercializing this type of anode. Commercial battery anodes may have small amounts of silicon, boosting their performance slightly.
The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries. The research is published in Nature Materials.

The first laboratory experiments with lithium-silicon materials took place in the early to mid 1970s. Silicon carbon composite anodes were first reported in 2002 by Yoshio. Studies of these composite materials have shown that the capacities are a weighted average of the two end members (graphite and silicon). On cycling, electronic isolation of the silicon particles tends to occur with the capacity falling off to the capacity of the graphite component. This effect has bee…
