Problems solved by technology

[0002] The sealing radius of the ring edge of the positive metal shell of the traditional button battery is 0.8mm, and the strength and stability of the battery after sealing are low, and the working efficiency of the battery sealing machine is also very low.
At the same time, the metal shell of the negative electrode is higher than the upper surface of the metal shell of the positive electrode by a large distance, which is very similar to the shape of a hat. The effective space inside the battery is greatly reduced, and the battery capacity is not very high.

Embodiment Construction

[0010] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0011] Such as figure 1 A button battery shown has a positive metal shell 1 and a negative metal shell 2 matching it, and a sealing ring 3 integrally structured with the negative metal shell 2, and the radius of the ring edge seal of the positive metal shell 1 is R is 1mm-1.4mm, the strength of the battery after sealing is high, the stability is also strong, and the efficiency of the sealing machine is increased by 2 times; the distance between the upper surface of the negative metal shell 2 and the upper surface of the positive metal shell 1 h is 0.9-1.1 mm, which is much smaller than the previous hat-shaped battery. Such a change greatly increases the effec...

Abstract

The invention relates to a button battery. The button battery has an anode metal shell, a cathode metal shell matched with the anode metal shell, and a sealing ring forming an integral structure together with the cathode metal shell, the ring edge seal radius R of the anode metal shell is 1-1.4mm, and the upper surface of the cathode metal shell is 0.9-1.1mm higher than the upper surface of the anode metal shell. The button battery has the advantages of high strength, strong stability, increased effective space in the battery, and increased capacity.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a button battery with high strength, strong stability, enlarged internal effective space and increased capacity. Background technique [0002] The sealing radius of the ring edge of the positive metal shell of the traditional button battery is 0.8mm, the strength of the battery after sealing is low, the stability is also poor, and the working efficiency of the battery sealing machine is also very low. At the same time, the metal casing of the negative electrode is higher than the upper surface of the metal casing of the positive electrode by a large distance, which is very similar to the shape of a hat. The effective space inside the battery is greatly reduced, and the battery capacity is not very high. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems raised in the above-mentioned background technology, th...
