Button battery with path cut-off protection function

Abstract

The invention relates to a button battery with a path cut-off protection function, which is provided with a packaging assembly and a battery roll core. In the actual application process, both a battery shell and a battery steel shell play a role of packaging and protection; a sealing rubber ring plays a role of sealing and water prevention; when the battery roll core expands unexpectedly, a cutting piece will hold a tab under the expansion of the battery roll core, the tab is made of a flexible material and the rigidity of a bending part is weak, and the bending part will be deformed and broken in the case that the cutting piece holds the tab, that is, the tab is disconnected from the roll core, and the voltage outputted by the roll core cannot be outputted to external power supply equipment through the broken tab, thereby effectively preventing the roll core from outputting voltage outward under the expansion state to result in corresponding safety accidents.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a button-type battery with a channel cut-off protection function. Background technique [0002] At present, a battery refers to a part of the space of a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate electrical current, a device that converts chemical energy into electrical energy. With positive and negative points. With the advancement of technology, batteries generally refer to small devices that can generate electricity, such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as an energy source can obtain a current with stable voltage, stable current, stable power supply for a long time, and little external influence, and the battery has a simple structure, easy to carry, simple and easy...

Problems solved by technology

[0003] In the existing battery structure, in order to realize the monitoring and management of the battery, a protective plate is usually installed in the battery structure. The protective plate plays the role of monitoring and managing the battery core in the battery structure, preventing the battery core from being damaged under extreme conditions. It is still in working condition. It can be said that the protection board is of great significance to the battery winding core. However, since the protection board is an electronic component, it is inevitable that the protection board may not work normally after a period of use. If the protection board If it cannot work normally, it will not be possible to monitor and manage the battery core in real time. If the user uses the battery under this condition, there will be a very large safety hazard.

As the core component of the battery structure, the battery core is very necessary to protect the battery core. For example, when the battery core expands due to unexpected factors, if the battery core still outputs voltage at this time, there is a very large safety hazard. Hidden dangers, in severe cases, the battery may explode or the battery electrolyte may erupt, endangering the personal safety of users
