6 FAQs about [Battery negative electrode material original]

Can a negative electrode be used as a lithium-ion battery material?

To be used as a lithium-ion battery material, it is, however, not enough that the material has a high electronic conductivity and a high surface area. A good negative electrode material also needs to undergo a reduction during the lithiation step and an oxidation during the subsequent delithiation step.

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 is the specific capacity of a negative electrode material?

Ideally, the specific capacity of a negative electrode material should be higher than 372 mA h g –1, that is, the specific capacity of graphite, which is the most commonly used negative electrode material at present.

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 is the thickness of a negative electrode?

For evaluation purposes, the film was punched into discs with a diameter of 12 mm. The average thickness of the positive electrode is 70 µm, while the thickness of the negative electrode is 30 µm.

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.
