A common material used for the positive electrode in Li-ion batteries is lithium metal oxide, such as LiCoO 2, LiMn 2 O 4 [41, 42], or LiFePO 4 , LiNi 0.08 Co 0.15 Al 0.05 O 2 . When charging a Li-ion battery, lithium ions are taken out of the positive electrode and travel through the electrolyte to the negative electrode.
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.
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives.
