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.
In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
For positive electrode materials, in the past decades a series of new cathode materials (such as LiNi 0.6 Co 0.2 Mn 0.2 O 2 and Li-/Mn-rich layered oxide) have been developed, which can provide a capacity of up to 200 mAh g −1 to replace the commercial LiCoO 2 (∼140 mAh g −1).
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.
