Embodiment 1

[0053] The button-type battery in this embodiment 1 includes a casing 20, a battery core 30, and a sealing member 40; the casing has a built-in battery core, the battery core contains electrolyte, and the sealing member is arranged on the casing; the casing and the battery core form a power supply path , the seal is used to seal the casing to prevent electrolyte leakage.

[0054] In Embodiment 1, the electrode case 20 is substantially cylindrical, and includes a positive electrode case 23 and a negative electrode case 24 . The positive and negative electrode cases form a seal 50 at the joint, and the seal 50 can be filled by compression and injection molding. The seals 40 are assembled together. The inside of the electrode housing forms a space for accommodating cells, which is used to set the cells. The electrode housing is used to conduct the circuit of the cells to output current. The sealing member seals the accommodating space to prevent dust from entering, and secondly, ...

Abstract

The wide-shape-application electrode for the button cell comprises an opening shell with a side wall, and at least part of the side wall in the circumferential direction of the opening shell forms a cut-out structure extending in the longitudinal direction of the opening shell. The open shell with the cut-out structure is matched with the mounting structure in shape, so that misconnection-preventing and easy-positioning mounting of the button cell is realized. According to the invention, the traditional shape of a cylindrical button cell is changed, so that irregular shapes with special requirements, such as TWS earphones, can be met, and the requirements of modern product design are better met. In addition, by means of the structure, the technical effects that common batteries are prevented from being connected mistakenly, and specific batteries are guaranteed to be installed on specific occasions can be achieved. Besides, the appearance of the cylindrical button cell is improved, so that the cylindrical button cell is easier to produce and manufacture, particularly, the side wall with a cutting structure is easy to mechanically grab, and a formed product is easier to mount and position during use.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more particularly, to an electrode and a button battery with a wide range of shapes for use in a button battery. Background technique [0002] With the wider application of smart wearable products, people's demand for small-sized lithium-ion button-type secondary rechargeable batteries is also growing. Button batteries are increasingly used in smart wearable products, such as earphones. The need for button-type lithium-ion batteries in smart wearable products is not limited to cylindrical shapes. For example, special TWS headphones. Cylindrical button batteries can not cope with some special requirements, and the shape of traditional cylindrical button batteries needs to be improved. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to solve the above-mentioned defects and deficiencies, solve the technical problems of single button battery shape and...
