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.

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.

Is lithium a good negative electrode material for rechargeable batteries?

Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).

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.

Can Si-negative electrodes increase the energy density of batteries?

In the context of ongoing research focused on high-Ni positive electrodes with over 90% nickel content, the application of Si-negative electrodes is imperative to increase the energy density of batteries.

Why should a negative electrode be mixed with graphite?

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. In order to avoid this problem, mixing with graphite has favorable effects.
