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.
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.
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.
In addition to lithium metal and carbon-based materials, a large number of alternative possibilities for the anode of the lithium-ion cell have been recently reported in the literature. The diversity in chemical elements and reaction mechanisms clearly demand a systematic study.
However, the use of lithium metal as anode material in rechargeable batteries was finally rejected due to safety reasons. What caused the fall in the application of rechargeable lithium-anode batteries is also well known and analogous to the origin of the lack of zinc anode rechargeable batteries.
In addition, from a structural point of view, the crystal structure of conversion-type electrode undergoes a complete disintegration and rearrangement during initial cycles. Thus, the structural evolutions of electrode materials during subsequent lithiation/delithiation undergo different pathways from those of initial reactions.
