Embodiment 1

[0045] Such as Figure 2 to Figure 6 As shown, an explosion-proof, heat-insulated and flame-retardant battery pack includes twenty monomers of explosion-proof, heat-insulated and flame-retardant batteries 60 (the number and wiring method of the explosion-proof, heat-insulated and flame-retardant batteries 60 not limited by this) for series or parallel connection.

[0046] The single unit of the explosion-proof, heat-insulated and flame-retardant battery 60 includes an explosion-proof case and a battery main body 20. The battery main body 20 has a positive electrode terminal 21 and a negative electrode terminal 22. The explosion-proof case wraps and seals the battery main body 20; the explosion-proof case has at least a first shell Section 11, the second shell section 12 and the third shell section 13, the first shell section 11 and the third shell section 13 are all made of conductive material, the second shell section 12 is made of insulating material, the first shell section...

Embodiment 2

[0058] Such as Figure 7 As shown, in this embodiment, there are six battery bodies 20 disposed in the explosion-proof casing 10 (the number and wiring methods of the battery bodies 20 are not limited by this), and each battery body 20 is connected in series or in parallel. Other structures of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

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...
