The performance of electrolytes with silicon-based anodes. Severe volume expansion during the lithiation and de-lithiation process of Si particles, low intrinsic conductivity and slow ion diffusion, and the unstable solid–electrolyte interfaces significantly inhibited the further improvement in the performance of the Si-based materials.
Due to the volume expansion of Si material when embedded with lithium, there is a risk of loss of active material on the electrode and destruction of surface SEI film, resulting in continuous electrolyte decomposition. Finally, the active Li + in the battery is consumed.
Silicon based electrodes present a decreasing gravimetric capacity for increasing current densities (see Supplementary Fig. S5). This behavior is due to the kinetic properties of the lithiation/delithiation process of silicon 25, since this is the limiting step in electrode charging and discharging.
Silicon (Si), the second-largest element outside of Earth, has an exceptionally high specific capacity (3579 mAh g −1), regarded as an excellent choice for the anode material in high-capacity lithium-ion batteries. However, it is low intrinsic conductivity and volume amplification during service status, prevented it from developing further.
An analytical model is proposed to investigate properties of composite electrodes that utilize more than one active material. We demonstrate how the equations can be applied to aid in the design of electrodes by comparing silicon-graphite and tin-graphite composite negative electrodes as examples with practical relevance.
