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.
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 lithium-ion battery generates a voltage of more than 3.5 V by a combination of a cathode material and carbonaceous anode material, in which the lithium ion reversibly inserts and extracts. Such electrochemical reaction proceeds at a potential of 4 V vs. Li/Li + electrode for cathode and ca. 0 V for anode.
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.
The positive electrode is activated carbon and the negative electrode is Li [Li 1/3 Ti 5/3 ]O 4. The idea has merit although the advantage of lithium-ion battery concept is limited because the concentration of lithium salt in electrolyte varies during charge and discharge.
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.
