[0002] Batteries are widely used in notebook computers, camcorders, digital cameras, and electric vehicles. However, because the battery is in some harsh high-temperature environments, the temperature inside the battery will further increase, so that the electrode material or electrolyte inside the battery will A reaction occurs to produce some gases, such as oxygen and hydrogen, and as time accumulates, the pressure inside the battery increases, resulting in an explosion

Embodiment Construction
[0016] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0017] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention discloses a battery not exploding at a high temperature. The battery comprises a battery cover, a metal shell, a cell and an explosion-proof assembly, the metal shell is a cylindrical hollow cavity structure with one opened end and one sealed end, the battery cover and the opening of the metal shell are closed to form an accommodation chamber, and the cell is squeezed in the explosion-proof assembly. The cell comprises a negative electrode sheet, a positive electrode sheet and a diaphragm, the explosion-proof assembly comprises a supporting plate, an elastic supporting rack, a pressure plate, a safety disc and an insulating layer, and a conical nail is arranged below the safety disc. The battery not exploding at the high temperature is provided with the battery cover, the metal shell, the cell and the explosion-proof assembly, the explosion-proof assembly makes the negative electrode sheet and the positive electrode sheet insulated when the battery is in a normal state, and the insulating layer is melted at the high temperature to form short circuit of the battery, so the battery does not explode. The conical tail arranged in the invention saves the short circuit formation time of the negative electrode sheet and the positive electrode sheet and improves the use safety of the battery.
Description
technical field [0001] The invention relates to a battery, in particular to an explosion-proof battery at high temperature. Background technique [0002] Batteries are widely used in notebook computers, camcorders, digital cameras, and electric vehicles. However, because the battery is in some harsh high-temperature environments, the temperature inside the battery will further increase, so that the electrode material or electrolyte inside the battery will A reaction occurs to produce some gases, such as oxygen and hydrogen, and as time accumulates, the pressure inside the battery increases, resulting in an explosion. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an explosion-proof battery at high temperature, which will not explode at high temperature, and the battery can be quickly short-circuited through an explosion-proof component to improve the safety of the battery. [0004] The p...
