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
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.
In recent years, the primary power sources for portable electronic devices are lithium ion batteries. However, they suffer from many of the limitations for their use in electric means of transportation and other high level applications. This mini-review discusses the recent trends in electrode materials for Li-ion batteries.
The battery functions through the catalytic reduction of oxygen in an alkaline aqueous electrolyte and metallic lithium in a non-aqueous electrolyte, such as a solid ceramic polymer electrolyte, glass, or glass-ceramic electrolyte (Wang and Zhou, 2010, Capsoni et al., 2015, Imanishi and Yamamoto, 2019).
These lithium ions migrate through the electrolyte medium to the cathode, where they are incorporated into lithium cobalt oxide through the following reaction, which reduces cobalt from a +4 to a +3 oxidation state: CoO2 (s) + Li+ + e– → LiCoO2 (s) Here is the full reaction (left to right = discharging, right to left = charging):
