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.
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.
Recently, A123Systems Inc. announced a high-power lithium-ion batteries consisting of a LiFePO 4 -positive electrode and graphitic carbon-negative electrode as power sources for power tools.
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 .
