Embodiment 1

[0021] see Figure 1-2 , the present embodiment provides a bendable lithium battery, including several lithium battery casings 3, several rotating sleeves 2 and several FPC flexible circuit boards 6, and the inner cavities of several lithium battery casings 3 are embedded with Lithium battery 11, several FPC flexible circuit boards 6 all include positive electrode flexible circuit board 61 and negative electrode flexible circuit board 62, the positive and negative poles of two adjacent lithium batteries 11 are connected with the positive electrode flexible circuit board of each FPC flexible circuit board 6 respectively. The plate 61 is connected to the negative electrode flexible circuit board 62, and the inner cavities of several rotating sleeves 2 are all hollow structures, and the bottom of the mountain is transparent. The outer wall of the sleeve 2 is provided with a plastic buckle 1 , and the plastic buckle 1 is rotated between two adjacent lithium battery casings 3 and c...

Embodiment 2

[0024] see Figure 1-2 , further improvements have been made on the basis of Example 1:

[0025] Several lithium battery casings 3 and the lithium batteries 11 embedded in the inner cavity of the lithium battery casing 3 are all in a cylindrical structure, which is convenient for rotation and bending.

[0026] The top of the outer wall of each lithium battery case 3 is provided with an annular rotating slot 9, and the inner cavity side wall of each rotating sleeve 2 protrudes radially from the same body with an annular rotating block 10, and each rotating sleeve 2 rotates through the ring. The clamp block 10 is engaged with the inner cavity of the annular rotating slot 9 of each lithium battery case 3 so that the rotating sleeve 2 will not break away from the lithium battery case 3, and this facilitates the circular rotation of the rotating sleeve 2 on the lithium battery case 3 The inner cavity of the card slot 9 is free to rotate and bend, and is suitable for most electroni...

Abstract

The invention discloses a flexible lithium battery, which comprises a plurality of lithium battery housings, a plurality of rotating sleeves and a plurality of FPCs, wherein lithium batteries are embedded into inner cavities of the plurality of lithium battery housings separately; each of the plurality of FPCs comprises a positive flexible circuit board and a negative flexible circuit board; positive electrodes and negative electrodes of two adjacent lithium batteries are connected with the positive flexible circuit board and the negative flexible circuit board of each FPC respectively; the inner cavities of the plurality of rotating sleeves are of a hollow structure and are transparent from top to bottom; each rotating sleeve rotationally sleeves the top of an outer wall of one lithium battery housing; a plastic buckle is arranged on the outer wall of each rotating sleeve; and two adjacent lithium battery housings are rotationally clamped on the outer walls of the rotating sleeves through the corresponding plastic buckles. The whole flexible lithium battery disclosed by the invention can be rotationally folded freely and can be matched with the appearance structures of most curvedelectronic products for use, so that the application range of the lithium battery is expanded.

Description

technical field [0001] The invention relates to the technical field related to lithium batteries, in particular to a bendable lithium battery. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. With the continuous expansion of the application field of lithium battery, its shape is fixed, and it needs to be used in many electronic devices. However, as people live With the improvement of the level, people's demand is also increasing, and many curved products also need to use lithium batteries, but it is difficult for this kind of fixed lithium battery to be loaded into such curved electronic products, which brings great difficulties to manufacturers. It is a big trouble, and a bendable lithium battery is designed here to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a bendable...
