Electric current is generated when lithium ions migrate from the negative electrode (anode) to the positive electrode (cathode) through the electrolyte during discharge. Reversing this process results in intercalation of lithium ions back into the anode and their removal from the cathode to produce the charged state. (In practice, cells are
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.

Since lithium metal functions as a negative electrode in rechargeable lithium-metal batteries, lithiation of the positive electrode is not necessary. In Li-ion batteries, however, since the carbon electrode acting as the negative terminal does not contain lithium, the positive terminal must serve as the source of lithium; hence, an

Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious decrease in capacity. An

For positive electrodes with layered oxides, a conductive additive is used to ensure sufficiently good electronic conductivity owing to the low electronic conductivity of the active material. 1 However, in high-energy batteries, the contents of conductive carbon and binder need to be as small as possible to ensure electrode porosity. Therefore, to optimize the design

Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode. Cathode active material in Lithium Ion battery are most likely metal oxides. Some of the common CAM are given below
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
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.
