Explosion-proof, thermal-insulation and flame-retardant battery, battery pack and application method of explosion-proof, thermal-insulation and flame-retardant battery

Abstract

The invention discloses an explosion-proof, thermal-insulation and flame-retardant battery, a battery pack and an application method of the explosion-proof, thermal-insulation and flame-retardant battery. The explosion-proof, thermal-insulation and flame-retardant battery comprises an explosion-proof shell and a battery main body, wherein the battery main body is provided with a positive terminal and a negative terminal, the explosion-proof shell wraps and seals the battery main body and at least is provided with a first shell segment, a second shell segment and a third shell segment, the first shell segment and the third shell segment are both made of conductive materials, the second shell segment is made of insulation material, the first shell segment is electrically connected with the positive terminal of the battery main body, the third shell segment is electrically connected with the negative terminal of the battery main body, and the thermal-insulation and flame-retardant shell at least wraps a side wall of the explosion-proof shell. By the explosion-proof, thermal-insulation and flame-retardant battery, subsequent chain reaction brought by battery explosion can be effectively relieved, and the reliability and the safety are improved.

Description

technical field [0001] The invention belongs to the field of batteries, and in particular relates to an explosion-proof, heat-insulating and flame-retardant battery, a battery pack and a use method thereof. Background technique [0002] The role of the battery is to provide energy for electrical appliances, which is already indispensable in our daily life, such as: batteries for electric vehicles, batteries for mobile phones, and so on. [0003] The principle of the battery is to fill the casing with an electrolyte, and the metal generates positive charges and external charges when it is electrolyzed in the electrolyte, and then forms a current; an important problem that the existing batteries need to face is: how to avoid or solve the explosion of the battery, the battery Explosion will bring serious harm to users. In order to solve the explosion problem of the battery, people have made many structural improvements in the structure of the battery, but the reliability of th...
