The major components of a battery include the anode (or negative electrode) and the cathode (or positive electrode), the electrolyte, the separator and the current collectors. In addition to these primary components, batteries may also incorporate other components like current-limiting devices, safety features and thermal management systems
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
In Li-ion batteries, carbon particles are used in the negative electrode as the host for Li +-ion intercalation (or storage), and carbon is also utilized in the positive electrode to enhance its electronic conductivity.

Comparison of positive and negative electrode materials under consideration for the next generation of rechargeable lithium- based batteries [6] Chapter 3 Lithium-Ion Batteries . 3 . 1.1. Nomenclature . Colloquially, the positive electrode in Li -ion batteries is routinely referred to as the "cathode" and the negative electrode as the "anode." This can lead to confusion because
The cathode is the positive electrode, where reduction (gain of electrons) occurs, while the anode is the negative electrode, where oxidation (loss of electrons) takes place. During the charging process in a battery, electrons flow from the cathode to the anode, storing energy that can later be used to power devices
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.

Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
For lithium-ion batteries, the most in-depth studied material for the cathode is cobalt oxides and lithiated nickel. The high stability of structure characterizes both of them. They are expensive and difficult to make as the resources are limited. In the development of these layered compounds’ solid solutions, there is a resolution.
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.
