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.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
It is not clear how one can provide the opportunity for new unique lithium insertion materials to work as positive or negative electrode in rechargeable batteries. Amatucci et al. proposed an asymmetric non-aqueous energy storage cell consisting of active carbon and Li [Li 1/3 Ti 5/3]O 4.
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.
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 , .
In particular, the recent trends on material researches for advanced lithium-ion batteries, such as layered lithium manganese oxides, lithium transition metal phosphates, and lithium nickel manganese oxides with or without cobalt, are described.
