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.
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.
Silicon, one of the most promising candidates as lithium-ion battery anode, has attracted much attention due to its high theoretical capacity, abundant existence, and mature infrastructure. Recently, Si nanostructures-based lithium-ion battery anode, with sophisticated structure designs and process development, has made significant progress.
A long-standing goal for anode innovation with lithium batteries has been to leverage silicon as an active material inside of the anode, creating a lithium-silicon battery. Lithium-silicon batteries have the potential to hold huge amounts of lithium ions due to silicon’s 10x higher capacity than graphite.
Batteries with a small amount of Si have already been commercialized; interestingly, Tesla Motors incorporated Panasonic lithium-ion cells with a SiO x and carbon-based anodes in their Model X and Model 3 vehicles, demonstrating the practical implementation of these advancements (5% of Si in the anode of the Panasonic cells of the Tesla X) .
Besides silicon itself as active material, other anode components, such as polymer binders and electrically conductive carbon phases, play significant roles in the silicon-based electrode stability and the overall lithium-ion battery performance.
