What causes a SEI layer on a negative electrode surface?

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.

Why does a negative electrode have a poor cycling performance?

The origins of such a poor cycling performance are diverse. Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge.

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.

Can nibs be used as negative electrodes?

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.

Which metals can be used as negative electrodes?

Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.

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.
