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 commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
The active materials in the electrodes of commercial Li-ion batteries are usually graphitized carbons in the negative electrode and LiCoO 2 in the positive electrode. The electrolyte contains LiPF 6 and solvents that consist of mixtures of cyclic and linear carbonates.
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
It should be noted that the potential applicability of this anode material in commercial lithium-ion batteries requires a careful selection of the cathode material with sufficiently high voltage, e.g. by using 5 V cathodes LiNi 0.5 Mn 1.5 O 4 as positive electrode.
