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.
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 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.
The ratio of specific capacity of positive and negative electrode is the inverse ratio of respective active masses. For safety and lifetime reasons, the practically required capacity of negative electrode needs to be increased, thus leading to an increase of negative electrode's mass and finally to (N:P) m active mass ratio.
The cathode material for the lithium-ion battery is synthesized by baking after mixing the lithium salt with the raw hydroxide. In this case, it also is important to maintain the particle shapes of raw materials by controlling the heating condition.
