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.
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.
This review gives an account of the various emerging high-voltage positive electrode materials that have the potential to satisfy these requirements either in the short or long term, including nickel-rich layered oxides, lithium-rich layered oxides, high-voltage spinel oxides, and high-voltage polyanionic compounds.
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.
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.

Recent trends and prospects of anode materials for Li-ion batteries The high capacity (3860 mA h g −1 or 2061 mA h cm −3) and lower potential of reduction of −3.04 V vs primary reference electrode (standard hydrogen electrode: SHE) make the anode metal Li as significant compared to other metals , .
