The positive electrode material accounts for a large proportion in lithium-ion batteries (the mass ratio of positive and negative electrode materials is 3:1 to 4:1), so the performance of the positive electrode material will greatly affect the battery performance, and its cost directly determines the cost of the battery. 2.
Evaluate different properties of lithium-ion batteries in different materials. Review recent materials in collectors and electrolytes. Lithium-ion batteries are one of the most popular energy storage systems today, for their high-power density, low self-discharge rate and absence of memory effects.
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.
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.
However, energy density of a lithium-ion battery consisting of LiFePO 4 and graphite is less than that of current lithium-ion batteries mainly due to its lower operating voltage and smaller density than LiCoO 2.
