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 energy capacity: for example, 3600 mAh/g for pristine silicon. The standard anode material graphite is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC6. Silicon''s vast volume change (approximately 400% based on crystallographic densities) when lit

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 energy capacity: for example, 3600 mAh/g for pristine silicon.
Silicon is found at or near to just about every location on the planet. More to the point, one of silicon’s lesser-known desirable properties is that can absorb a whole lot of lithium ions; theoretically, around 10 times the number as graphite, which is the current go-to material for Li-ion battery anodes. Well, why not silicon?
Lithium-silicon batteries also include cell configurations where silicon is in compounds that may, at low voltage, store lithium by a displacement reaction, including silicon oxycarbide, silicon monoxide, or silicon nitride. The first laboratory experiments with lithium-silicon materials took place in the early to mid-1970s.
Therein lies the conundrum. While a silicon-anode Li-ion battery could theoretically offer 10 times the storage capacity of a same-sized graphite-anode Li-ion battery, it would, without constraint, swell far beyond its uncharged size–by as much as three to four times, depending on who you talk to.
Silicon-based materials, generally, have a much larger specific energy capacity: for example, 3600 mAh/g for pristine silicon. The standard anode material graphite is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC 6.
According to Enovix, with a normal jelly-rolled, single-cell Li-ion battery design, constraining the aforementioned silicon swelling would require something along the lines of 1.7 tons of constraining force for a cellphone-sized battery.
