The charge/discharge curves of LiCoO2 and LiNiO2 are shown in Fig. 2.4. When the cutoff voltage is selected to be 4.3 V, LiCoO2 has a comparatively smooth curve, while LiNiO2 has a complicated curve with some voltage plateaus. In the following, the composition of the LiNiO2-type compound during the.

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.
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 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.
It is an ideal insertion material for long-life lithium-ion batteries, with about 175 mAh g −1 of rechargeable capacity and extremely flat operating voltage of 1.55 V versus lithium. LiFePO 4 in Fig. 3 (d) is thermally quite stable even when all of lithium ions are extracted from it .
The cathode materials of lithium batteries have a strong oxidative power in the charged state as expected from their electrode potential. Then, charged cathode materials may be able to cause the oxidation of solvent or self-decomposition with the oxygen evolution. Finally, these properties highly relate to the battery safety.
