Abstract

The invention provides a button battery with an explosion-proof structure. The bottom battery comprises an outer metal shell, an inner metal shell, an insulating rubber ring and a battery cell, the edge of the outer metal shell comprises a sealing part for extruding the insulating rubber ring and an opening part for exposing the insulating rubber ring, and the sealing part and the opening part arearranged in a staggered manner. According to the invention, the edge of the outer metal shell is provided with the sealing part and the opening part, so that the binding force between the outer metalshell and the inner metal shell or between the outer metal shell and the metal cover plate is adjusted, and the outer metal shell and the inner metal shell or the outer metal shell and the metal cover plate are combined to form the explosion-proof valve.

Description

technical field [0001] The invention relates to the battery field, in particular to a button battery with an explosion-proof structure. Background technique [0002] There are a wide variety of electronic products in modern society, and electronic products are generally inseparable from the batteries that power them. Among them, the button battery is often used in various electronic products due to its thin thickness and small size. When the button battery in the prior art is subjected to unconventional operations such as fire roasting and violent impact, the battery is prone to heat up, the internal gas increases, the air pressure increases, and the outer metal shell is broken to release energy, causing the battery to catch fire, explode, etc. possible. [0003] Therefore, it is necessary to provide a button battery with an explosion-proof structure to solve the above technical problems. Contents of the invention [0004] The invention provides a button battery with an...
