Abstract: An electrode structure of a lithium ion battery includes a current collector, at least one energy type active layer, and at least one power type active layer. The energy type active layer and the power type active layer are formed on the current collector. The energy type active layer includes a first lithium-containing compound and multiple first conductive particles. The power type active layer includes a second lithium-containing compound and multiple second conductive particles. The first and second lithium-containing compounds are lithium-containing complex transitional metal oxides. Compositions of the first and second lithium-containing compounds include at least one of Ni, Co and Mn. A lithium ion diffusion coefficient of the second lithium-containing compound is greater than that of the first lithium-containing compound. A specific capacity of the first lithium-containing compound is greater than that of the second lithium-containing compound.
