Is silicon a promising anode material for a lithium-ion battery?

The challenge and directions for future research is proposed. Silicon (Si) is one of the most promising anode materials for the next generation of lithium-ion battery (LIB) due to its high specific capacity, low lithiation potential, and natural abundance.

Which anode materials are used for Li-ion batteries?

Anode materials for Li-ion batteries (LIBs) utilized in electric vehicles, portable electronics, and other devices are mainly graphite (Gr) and its derivatives. However, the limited energy density of Gr-based anodes promotes the exploration of alternative anode materials such as silicon (Si)-based materials

What are the components of a lithium ion battery?

Lithium-ion batteries are composed of a cathode, an anode, a separator, and an electrolyte. The cathode and anode store electrical energy in the form of chemical energy. When charging a battery, the key considerations include stability, energy density, and cycle life [13, 14, 15].

What is a lithium ion battery?

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.

Which anode materials can increase the energy density of Li-ion batteries?

Silicon and its oxides remain the most promising and alternative anode materials for increasing the energy density of Li-ion batteries (LIBs) due to their high theoretical specific capacity and suitable operating voltage.

What is a lithium-silicon battery?

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.
