[0040] The embodiments of the present invention will be described in detail below:
[0041] Such as Figure 4 , 5 As shown, an electrode assembly provided by the present invention includes a first electrode plate 21 and two second electrode plates 22, both sides of the first electrode plate 21 are coated with an active material layer 26, and the A pole plate 21 is continuously bent along the length direction of the first pole plate 21 into a Z-shaped vertical section. One surface of the second electrode plate 22 is coated with an active material layer 26, and the second electrode plate 22 is continuously bent along the length direction of the second electrode plate 22 into a zigzag vertical cross section. The two surfaces of the electrode plate 21 coated with the active material layer 26 are opposite to the surfaces of the two second electrode plates 22 coated with the active material layer 26, respectively. An isolation layer is provided between the opposite surfaces of the dio...
