Problems solved by technology

For the existing button batteries on the market, when there is an abnormality inside the button battery, a high voltage will be formed inside the battery. Under the high voltage state, the battery may explode. At present, the pressure is relieved by using pressure relief valves and other pressure relief methods for this situation. Prevent the battery from exploding, but after this pressure relief method, the battery still has electric energy inside, the battery will continue to discharge, and the battery still has safety risks

Abstract

The invention relates to a battery and electronic equipment. The battery comprises a first shell and a second shell; part of the second shell is arranged on the inner side of the first shell, and a first sealing part is arranged between the first shell and part of the second shell; a second sealing part is arranged on the outer side wall of the second shell, a gap is formed between the second sealing part and the first sealing part, a conductive part is arranged on the gap, and the conductive part is electrically connected with the second shell at the gap; and the first shell is provided with a crimping part, when the battery is in a first state, at least part of the end part of the crimping part abuts against the second sealing part, and when the battery is in a second state, the crimping part is configured to be electrically connected with the conductive part.

Description

technical field [0001] The present disclosure relates to the field of battery technology, and more specifically, the present disclosure relates to a battery and an electronic device. Background technique [0002] Button batteries are generally larger in diameter and thinner in thickness. For the existing button batteries on the market, when there is an abnormality inside the button battery, a high voltage will be formed inside the battery. Under the high voltage state, the battery may explode. At present, the pressure is relieved by using pressure relief valves and other pressure relief methods for this situation. Prevent the battery from exploding, but after this pressure relief method, the battery still has electric energy inside, the battery will continue to discharge, and the battery still has safety risks. Contents of the invention [0003] An object of the present disclosure is to provide a battery and an electronic device. [0004] According to a first aspect of t...
