In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
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.
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.
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.
Since the cracking of carbon materials when used as negative electrodes in lithium batteries is very small, several allotropes of carbon can be used, including amorphous carbon, hard carbon, graphite, carbon nanofibers, multi-walled carbon nanotubes (MWNT), and graphene .
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.
