Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] see figure 2 , a preferred embodiment of the present invention provides a flexible battery 100 . The flexible battery 100 can be applied to products that need to be bent. The flexible battery 100 includes a casing 10 , a plurality of battery cells 20 and a current collecting unit 30 . The shell 10 is a shell with a certain degree of flexibility, so as to match the flexible battery 100 to a certain degree of bending. The casing 10 is used for accommodating the plurality of battery cells 20 and the current collecting unit 30 . The plurality of battery cells 20 are accommodated in the casing 10 at intervals. Preferably, the plurality of battery cells 20 are arranged side by side and at intervals. Correspondingly, the casing 10 can be bent along the arrangement direction of the plurality of electric cores 20 , but cannot be bent along the axial direction of the...

Abstract

The invention relates to a flexible battery, which includes a shell. The flexible battery also includes a plurality of battery cells and a current collecting unit. The battery cells are arranged at intervals in the shell. The current collecting unit is arranged in the shell to electrically connect the battery cells. According to the flexible battery provided by the invention, the multiple small battery cells are electrically connected together to replace a single large battery cell, so that the isolation film cannot be easily broken down under the condition of realizing the flexibility of theflexible battery.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a flexible battery. Background technique [0002] In recent years, with the gradual maturity of Organic Light-Emitting Diode (OLED) technology, flexible electronic products have become a design consideration, and there is a demand for flexible batteries. see figure 1 In an existing lithium polymer flexible battery 200 , the positive electrode sheet 62 , the negative electrode sheet 64 and the separator 66 are sequentially stacked and wound to form a battery cell 60 which is placed in the flexible battery casing 70 . However, since the separator 66 is very thin, and the positive electrode sheet 62 and the negative electrode sheet 64 are coated with granular electrode materials, the separator 66 is easily broken down when the flexible battery 200 is bent. As a result, the flexible battery 200 catches fire. Contents of the invention [0003] The purpose of the present inventi...
