Abstract

The invention discloses an electrolyte supplementing device applied to soft package lithium cell production. A conveying belt is arranged right above a device base, a battery bracket is connected right above the conveying belt in a clamping manner, the outer side of the conveying belt is in shaft connection with a guide back plate, and a rectangular clamping groove is formed right above the conveying belt. The device comprises a liquid storage box body, wherein a driving water pump is connected to the upper surface of the base in a penetrating mode, a liquid injection pipeline is connected to the output end of the driving water pump, a liquid injection needle is fixedly nested to the outer side of the liquid injection pipeline, and a sealing force arm is arranged on one side of the liquid injection needle; and the sealing force arm. The invention discloses an electrolyte supplementing device and method applied to production of a soft package lithium battery cell. The battery bracket and the clamping force arm b are arranged, the clamping force arm a at the bottom of the battery bracket is used for clamping and limiting the upper surface of the conveying belt, the clamping force arm a is clamped and fixed according to the width of a clamping groove of the conveying belt, and the stability of the battery bracket in the assembling and locking process is ensured.

Description

technical field [0001] The invention relates to the technical field of production of soft-packed lithium batteries, in particular to an electrolyte replenishment device and method applied to the production of soft-packed lithium batteries. Background technique [0002] At present, the general practice in the industry is to fold the tabs of the two batteries separately, so that the electrode tabs of the two batteries overlap, and through a mechanical connection method, the tabs of the two batteries are tightly connected to achieve the purpose of conduction. , Generally, in the process of processing, it is necessary to add a certain degree of electrolyte to the soft-packed lithium battery. After the electric vehicle power battery enters a large number of recycling stages, it can be considered to use the power battery in gradients. Generally, the battery surface is cut. , it is convenient for supplementary treatment of battery electrolyte, and it is convenient for second-hand r...

Problems solved by technology

[0006] The object of the present invention is to provide an electrolyte replenishment device and method applied to the production of soft-packed lithium batteries, so as to solve the above-mentioned background technology. The clamping and limiting structure causes the electrolyte to easily corrode the lithium battery shell and the outside of the device during the operation of the lithium battery. The single packaging structure cannot effectively seal the battery itself, resulting in , the current market problem that the opening position of the battery is prone to leakage
