[0002] With the continuous research and development of batteries, sodium-ion batteries have gradually attracted attention because the earth has a sufficiently high abundance of sodium. Sodium-ion batteries not only provide energy for portable electronic devices, but also for aviation, military, medical and transportation.

[0003] However, in existing devices, most batteries are plate-shaped or cylindrical, and the shape of the battery cannot be changed according to demand, resulting in a small range of use for sodium batteries. For this reason, an ultra-thin sodium-ion battery that can be bent into an arc is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an ultra-thin sodium ion battery that can be bent into an arc shape.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an ultra-thin sodium-ion battery that can be bent into an arc shape, comprising a positive electrode frame, wherein the opposite sides of the positive electrode frame are wavy, the bottom of the positive electrode frame is fixedly connected to a positive electrode ear, the inner wall of the positive electrode frame is fixedly connected to a diaphragm, and the opposite side of the diaphragm is fixedly connected to a plurality of negative electrode columns, wherein the upper surface of one of the negative electrode columns is fixedly connected to a negative electrode ear, the upper surfaces of the plurality of negative electrode columns are fixedly connected to two connecting columns, and the upper surfaces of two of the negative electrode columns are fixedly connected to a connecting column, and the connecting columns on the two adjacent negative electrode columns are rotatably connected to a connecting rod together, and each of the connecting rods is provided with a fixing structure.

[0006] As a further description of the above technical solution:

[0007] A sliding hole is provided on one side of the interior of the connecting rod, and a sliding groove is provided on the upper surface of the connecting rod.

[0008] As a further description of the above technical solution:

[0009] The fixing structure comprises two fixing plates fixedly connected to the inner side wall of the sliding hole, and a sliding rod is slidably connected through one side of each fixing plate.

[0010] As a further description of the above technical solution:

[0011] One side opposite to the two sliding rods is in the shape of an inclined plane. One end of the two sliding rods away from each other is fixedly connected with a moving block. The two moving blocks are slidably connected in the sliding hole.

[0012] As a further description of the above technical solution:

[0013] The upper surface of the connecting rod is fixedly connected to a fixed frame, and the upper surface of the fixed frame is slidably connected to a pull rod. One end of the pull rod is fixedly connected to an extrusion block, and the extrusion block is slidably connected in the sliding groove. The side of the extrusion block away from each other is respectively fitted with the inclined surfaces of the corresponding two sliding rods.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the ultra-thin sodium-ion battery for arc bending is provided with connecting columns and connecting rods.

[0018] 2. Compared with the prior art, the ultra-thin sodium-ion battery for arc-bendable bending is provided with a fixed frame, a pull rod, an extrusion block, a spring, a fixed plate, a sliding rod and a movable block. When the pull rod is pulled, the pull rod drives the extrusion block to move, so that the extrusion block is separated from the two sliding rods, and then the curvature between the two negative poles on the connecting column is adjusted according to demand. Then, the pull rod is released, and the extrusion block is driven to move under the elasticity of the spring. The extrusion block drives the movable block to move through the sliding rod, so that the movable block squeezes and fixes the connecting column, thereby reducing the probability of curvature rebound after the overall adjustment of the sodium-ion battery.
