Lithium is the third element in the periodic table. It has the most negative electrode potential and is stable only in non-aqueous electrolytes. It was not popular electrode material in battery community before 1970. Purification of organic solvents and lithium salts to remove water was especially hard work in each laboratory.
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.
As anode materials offer a higher Li-ion storage capacity than cathodes do, the cathode material is the limiting factor in the performance of Li-ion batteries , . The energy density of a Li-ion battery is often determined collectively by the Li-ion storage capacity and the discharge potential of the cell.
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.
Apart from the discharge curves, the profiles of the charge curves are also correlated with the electronic structure of metal ions in the host. During the charge period, Li 2 RuO 3 and Li 2 MnO 3 show average electrochemical potentials of ∼3.5 V and ∼4.8 V vs. Li/Li +, respectively.
