5. Conclusion and perspective Silicon is considered one of the most promising anode materials for next-generation state-of-the-art high-energy lithium-ion batteries (LIBs) because of its ultrahigh theoretical capacity, relatively low working potential and abundant reserves.
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.
Batteries with a small amount of Si have already been commercialized; interestingly, Tesla Motors incorporated Panasonic lithium-ion cells with a SiOxand 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) .
