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.
Currently, the anode material of commercial lithium-ion batteries is mainly based on graphite with a theoretical specific capacity of (372 mAhg –1), (2) which limits the energy density of lithium-based batteries. (3) Silicon (Si) with a high specific capacity of (3590 mAhg –1) (4) is being considered as an alternative to graphite.
Hence, the utilization of crystalline Si has been identified as a promising material, not just for anodes in Li-ion batteries 9, 10, 11, 12, but also highly relevant to emerging technologies like all-solid-state-batteries 13, 14, 15, 16, 17.
Furthermore, the scalability of Li-Si production enhances its incorporation into current battery manufacturing processes, thus easing the shift towards advanced lithium-ion batteries with improved pre-lithiation capabilities. Considering the nature of Li-Si as lithiated Si, it can function both as the electrode and the pre-lithiation agent.
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.
