Problems solved by technology

However, due to the relatively high pressure that the steel shell material can withstand, when an acute short circuit occurs in the battery cell, the gas generated by the chemical reaction inside the battery cell cannot be discharged in time, and there is a risk of explosion
[0004] At present, there are also button batteries with soft package structure on the market, which are packaged with aluminum-plastic film. The pressure inside the battery cell is relatively small, and there is no risk of explosion. It is troublesome to carry out secondary welding on the tabs

Embodiment Construction

[0025] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", horizontal" etc. are based on th...

Abstract

The invention belongs to the technical field of batteries in particular to a laminated soft-package button battery. The battery comprises a first packaging film, a second packaging film and a laminated bare battery cell packaged between the first packaging film and the second packaging film, wherein a positive pole lug and a negative pole lug are led out of the laminated bare battery cell, the positive pole lug is conductively connected with the inner surface of the first packaging film, the negative pole lug is conductively connected with the inner surface of the second packaging film, and conductive areas are arranged on the outer surfaces of the first packaging film and the second packaging film. Compared with the prior art, the mode that a positive tab and a negative tab are led out of a packaging film by a conventional soft package button battery is avoided, the risk of explosion of the battery is reduced, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a laminated soft pack button battery. Background technique [0002] A button battery, also known as a button battery, refers to a battery that looks like a small button. Button batteries are widely used in various miniature electronic products due to their small size, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm; they are generally used as backup power for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc. [0003] Most of the existing button batteries adopt a steel shell structure, and the upper cover and the lower shell are sealed together by wrapping. The advantage of the steel case button battery is that the upper cover and the lower case can be used as positive and ne...
