6 FAQs about [Battery negative electrode material crushing mechanism picture]

What happens in the first stage of a battery crushing process?

In the first stage, the cell shell will deform at first elastically and then plastically. In the second stage, the jellyroll of the battery is crushed. Due to the gaps of the jellyroll or between different structures, the battery is continuously compacted during the crushing. The force will enhance with the increase of stiffness.

Can a negative electrode material be used for Li-ion batteries?

We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries.

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.

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.

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.

What are the cross sections of crushed cells under different impactors?

The cross sections of the crushed cells under different impactors were observed by an optical microscope (50X), as shown in Fig. 6. The obvious internal deformation of the cell is the negative electrode, where the white part is the collector copper foil, and the black on both sides is the negative electrode material graphite.
