Embodiment 1

[0030] Such as Figure 1-Figure 4 , the embodiment of the present invention provides a flexible mobile phone, including a flexible housing 1, a flexible circuit board (not shown), a flexible screen 2 and a flexible battery 3, the flexible circuit board and the flexible battery 3 are installed on the In the flexible housing 1, the flexible screen 2 is installed on one side of the flexible housing 1; the flexible circuit board is electrically connected to the flexible battery 3 through flexible wires, and the flexible screen 2 is The wire is electrically connected with the flexible circuit board. Among them, the components contained in the above-mentioned flexible mobile phone are the same as those contained in the existing ordinary mobile phones. It is no different from the assembly method of the existing common mobile phone. For example: the above-mentioned flexible battery 3 is electrically connected to the charging and discharging control system module of the flexible circ...

Embodiment 2

[0038] Such as Figure 5 , the embodiment of the present invention relates to a method for preparing a flexible pole piece, comprising the following steps:

[0039] Step 1, mixing and stirring the active material, conductive agent, binder and solvent to form a uniformly dispersed suspension;

[0040] Step 2, adding cellulose to the suspension and stirring to obtain viscous slurry 301;

[0041] Step 3, the viscous slurry 301 is laid on the metal mesh 302 by rolling film process, and the flexible pole piece is obtained after drying.

[0042]In the embodiment of the present invention, active material, conductive agent, binder, solvent and cellulose are used to prepare battery pole pieces. The binder can make the active material material adhere to the metal mesh 302 while maintaining the adhesion between the active material particles. knot effect; cellulose can play a supporting role. By laying the slurry on the metal mesh 302, the metal mesh 302 can play the role of a current c...

Abstract

The invention relates to a flexible pole piece, a preparation method of the flexible pole piece, a flexible battery using the flexible pole piece and a flexible mobile phone using the flexible battery. The preparation method of the flexible pole piece comprises the following steps: (1) mixing and stirring an active material, a conductive agent, an adhesive and a solvent to form a uniformly-dispersed suspension; (2) adding cellulose into the suspension, and stirring to obtain a viscous slurry; and (3) laying the viscous slurry on a metal net via a film rolling process, drying and then obtaining the flexible pole piece. According to the embodiment of the invention, the battery pole piece is prepared from the active material, the conductive agent, the adhesive, the solvent and cellulose; the cellulose can achieve a support effect and can ensure that the pole piece is high in flexibility and mechanical strength; the metal net can achieve an effect of a current collector, so that the mechanical strength of the pole piece can be further improved; a structure of combining the metal net and the slurry with support fiber can ensure that the pole piece still has high flexibility, the bending part is free of bending marks, and the material cannot fall off in the bending process.

Description

technical field [0001] The invention belongs to the technical field of mobile phones, and in particular relates to a flexible pole piece and a preparation method thereof, a flexible battery using the flexible pole piece and a bendable mobile phone using the flexible battery. Background technique [0002] In modern life, the mobile phone has become a household tool, but in the existing technology, most of the mobile phones are hardware structures. With the development of science and technology, the concept of bendable mobile phones has been proposed, and the investment in research and development of flexible mobile phones is also increasing. In addition, bendable mobile phone products have also come out. Among the products that have come out so far, the technologies of flexible shells, flexible circuit boards, and flexible touch screens have matured. However, due to the lack of flexibility and poor bending resistance of the battery, the traditional lithium-ion battery cannot ...
