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.
It is not clear how one can provide the opportunity for new unique lithium insertion materials to work as positive or negative electrode in rechargeable batteries. Amatucci et al. proposed an asymmetric non-aqueous energy storage cell consisting of active carbon and Li [Li 1/3 Ti 5/3]O 4.
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 .
Since lithium is more weakly bonded in the negative than in the positive electrode, lithium ions flow from the negative to the positive electrode, via the electrolyte (most commonly LiPF6 in an organic, carbonate-based solvent20).
Lithium-ion batteries consist of two lithium insertion materials, one for the negative electrode and a different one for the positive electrode in an electrochemical cell. Fig. 1 depicts the concept of cell operation in a simple manner . This combination of two lithium insertion materials gives the basic function of lithium-ion batteries.
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.
