Embodiment Construction

[0057] The present invention proposes a solution to the short circuit problem of the current collecting layer and the active material layer due to bending and separation of the flexible lithium battery after bending.

[0058] see figure 2 , as shown in the figure, the flexible lithium battery 30 of the present invention mainly includes a first collector layer 12 , a second collector layer 14 , a plastic frame 16 and an electrochemical system layer 26 . The first collector layer 12 has a first outer surface a and a first inner surface b. The second collector layer 14 has a second outer surface c and a second inner surface d. The plastic frame 16 is a closed structure and is sandwiched between the first inner surface b and the second inner surface d. The surface b and the second inner surface d of the second collector layer 14 are adhered, therefore, the plastic frame 16 , the first collector layer 12 and the second collector layer 14 form an enclosed space 18 . The electroc...
