Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
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
The phosphate positive-electrode materials are less susceptible to thermal runaway and demonstrate greater safety characteristics than the LiCoO 2 -based systems. 7. New applications of lithium insertion materials As described in Section 6, current lithium-ion batteries consisting of LiCoO 2 and graphite have excellence in their performance.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
Lithium is the third element in the periodic table. It has the most negative electrode potential and is stable only in non-aqueous electrolytes. It was not popular electrode material in battery community before 1970. Purification of organic solvents and lithium salts to remove water was especially hard work in each laboratory.

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 ...
