If mild oxidation is also effective in removing imperfections, then this method will have great promise for the use of LTC as the anode of lithium ion batteries because LTC has a higher reversible lithium capacity than the theoretic value for graphite, mainly due to the existence of a large amount of micropores acting as reservoirs for lithium storage [1] and its the

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.
The performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
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.
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
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 .
