Silicon is considered as one of the most promising candidates for the next generation negative electrode (negatrode) materials in lithium-ion batteries (LIBs) due to its high theoretical specific capacity, appropriate lithiation potential range, and fairly abundant resources.
This condition imposed by safety concerns implies that substituting for graphite with a material that has a higher specific capacity is desirable to increase the energy density of LIBs. In this chapter, we report on two types of silicon (Si) that can be employed as negative electrodes for lithium- (Li)-ion batteries (LIBs).
Summary A composite electrode model has been developed for lithium-ion battery cells with a negative electrode of silicon and graphite. The electrochemical interactions between silicon and graphite are handled by two parallel functions for lithium diffusion in silicon and graphite, with separate interfacial current densities from each phase.
Furthermore, because silicon particles rapidly fracture during cycling, the amount of silicon is normally limited to a small mass fraction, relative to graphite, in the negative electrode for commercial battery cells, e.g. ca. 10% for the LG M50 cells .
