Abstract

The invention discloses an assembly structure of a soft-pack battery, which comprises a soft-pack battery and an assembly shell of the soft-pack battery. The soft-pack battery is arranged in the assembled shell; The upper and lower sides of the soft-pack battery are respectively spaced apart from the top inner side and the bottom inner side of the assembled shell by a preset distance; A positive electrode ear and a negative electrode ear are arranged on the right side wall of the soft-pack battery at intervals; Wherein the positive electrode lug is connected with one end of a positive electrode conductor, and the other end of the positive electrode conductor is connected with a conductive block; The conductive block is fixedly arranged at the center position of the upper surface of the soft-pack battery; The negative electrode lug is connected with one end of a negative electrode lead, and the other end of the negative electrode lead is connected with the top inner side surface of theassembly shell. The invention can timely and effectively release the energy stored in the battery under the condition of abuse of the soft-pack battery, prevent the safety accidents such as combustionand explosion of the soft-pack battery, and ensure the safety performance of the soft-pack battery.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an assembly structure of a pouch battery. Background technique [0002] At present, lithium-ion power batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras and laptop computers, but also widely used in electric vehicles, electric In terms of large and medium-sized electric equipment such as bicycles and electric tools, the performance requirements of lithium-ion power batteries are getting higher and higher. [0003] For the soft-pack lithium-ion battery, it is popular in the market for its simple design, safety, and high energy density. However, the soft-pack battery will cause battery failure (such as thermal runaway) under abuse conditions (such as being squeezed or punctured by external force) ), if it is not handled in time and the ...
