In order to reduce the cost of battery and ensure a stable supply, the flow of cobalt-free positive electrode active materials is advancing. As the market for lithium-ion battery for automotive use expands, the challenge is to further improve energy density while reducing costs.
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.
Lithium ions can move back and forth between the positive and negative electrodes. This means they can move away from the graphite anode to the positive electrode during discharge and can then move back to it during charging. This mechanism works because of graphite's structure and chemical stability.
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).
