This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
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).
To maximize the cell performance and cycle life of the positive composite electrode with different composition ratios of AM, conductive additives, and binder materials, parameters such as electronic conductivity, interfacial resistance, and the dissolution of manganese (Mn) ions were used in this study.
As for the Co-based positive electrode (cathode) part of the battery, which is considered a central element determining energy-related properties, many Fe and Mn-based cathode materials fulfilling sustainability principles and delivering sufficient energy density and power have been sturdily pursued 12, 13, 14.
Alloy compounds have been considered as alternative negative electrodes for Na-ion batteries, as high storage capacity and low voltage operating materials.
Lead, tin, and calcium were the three main components. Other elements constitute ~0.02 wt% of the sample. Corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied. IL was selected as an effective additive for capacity tests of the positive electrode.
