What happens when a negative electrode is lithiated?

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.

Which material is used for negative electrode in lithium ion battery?

Thus, a lot of effort are paid to develop next generation materials for negative electrode for LIBs. Silicon is considered to be next generation anode material in lithium ion battery due to its high theoretical specific capacity of 4200 mAh g −1 4, low discharge voltage (~0.4 V versus Li + /Li), highly abundant resource and low toxicity.

Is Li-Si a promising lithium-containing negative electrode?

Due to the smaller capacity of the pre-lithiated graphite (339 mAh g −1 -LiC 6), its full-cell shows much lower capacity than the case of Li 21 Si 5 (0.2–2 μm) (Fig. 6b), clearly indicating the advantage of the Li-rich Li-Si alloy as a promising lithium-containing negative electrode for next-generation high-energy LIBs.

What are the limitations of a negative electrode?

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.
