6 FAQs about [Battery negative electrode material engineering infrastructure]

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 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.
