This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials.

In a battery, on the same electrode, both reactions can occur, whether the battery is discharging or charging. When naming the electrodes, it is better to refer to the positive electrode and the negative electrode. The positive electrode is the electrode with a higher potential than the negative electrode.

Lithium-ion battery (LIB) is one of rechargeable battery types in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and back when charging. It is the most popular choice for consumer electronics applications mainly due to high-energy density, longer cycle and shelf life, and no memory effect.

As a rule, the positive electrode of a lithium-ion battery consists of a porous active layer deposited on an aluminum current conductor. The active layer, in turn, consists of particles of active material, an electrically conductive additive and a binder. The pore space of the active layer is filled with liquid (or polymer) electrolyte.
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.
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.
Among the non-carbon materials of the negative electrodes of lithium-ion batteries, from the point of view of fast charging, traditional materials such as lithium titanate and silicon-based composites, as well as some non-trivial materials, are of interest.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
