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.
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).
The positive electrodes that are most common in Li-ion batteries for grid energy storage are the olivine LFP and the layered oxide, LiNixMnyCo1-x-yO2 (NMC). Their different structures and properties make them suitable for different applications .
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
Li-ion batteries come in various compositions, with lithium-cobalt oxide (LCO), lithium-manganese oxide (LMO), lithium-iron-phosphate (LFP), lithium-nickel-manganese-cobalt oxide (NMC), and lithium-nickel-cobalt-aluminium oxide (NCA) being among the most common. Graphite and its derivatives are currently the predominant materials for the anode.
For example, there has been much research into low- and no-Co positive electrodes. The proportion of metals in NMC positive electrodes has undergone an evolution from the original “111” mix (with an equal amount of nickel, manganese, and cobalt) to 532, 622, and 811 alloys.

What are battery anodes and cathodes? A cathode and an anode are the two electrodes found in a battery or an electrochemical cell, which facilitate the flow of electric charge. 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 ...
