    Abstract: A coating die head includes a first die block, a second die block, a third die block, and a fourth die block that are sequentially arranged at intervals. The first die block and the second die block form a first slot therebetween, the second die block and the third die block form a second slot therebetween, and the third die block and the fourth die block form a third slot therebetween. Each of the first die block, the second die block, the third die block, and the fourth die block has a die lip at a surface thereof. A length of the die lip of the second die block ranges from 100 micrometers to 200 micrometers. A ratio of a length of the die lip of the third die block to the length of the die lip of the second die block ranges from 1.5 to 7.

    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.
