For a negative electrode, the formation of SEI, which consists of inorganic Li 2 O, Li 2 CO 3, or LiOH, is attributed to the working potential below the chemical composition of the SEI on reduction potential of electrolytes. 31 By contrast, the chemical composition of the SEI formed on commercial graphite is generally similar to that formed on metallic lithium.

In the case of both LIBs and NIBs, there is still room for enhancing the energy density and rate performance of these batteries. So, the research of new materials is crucial. In order to achieve this in LIBs, high theoretical specific capacity materials, such as Si or P can be suitable candidates for negative electrodes.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.

During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
The interaction of the organic electrolyte with the active material results in the formation of an SEI layer on the negative electrode surface . The composition and structure of the SEI layer on Si electrodes evolve into a more complex form with repeated cycling owing to inherent structural instability.
So far, different methods have been developed for preparing negative electrode materials suitable for SIBs, but there is little mention of rate capabilities. 1 However, the ability to obtain attractive rates is one of the most important factors to obtain suitable electrodes for use in energy storage devices.
