Electrolyte automatic replenishment method

Abstract

The invention discloses an automatic liquid replenishing device, which comprises a decompression chamber, a fixed support and a timing and quantitative replenishment device. The fixed support is arranged in the decompression chamber, and a lever mechanism is hinged on the fixed support through a fixed pin, and one end of the lever mechanism is arranged There is a counterweight, the other end is provided with an electrolyte container, and an induction switch is provided under the counterweight. The electrolyte container is connected to the liquid inflow port of the timing quantitative supply device through a conduit, and the liquid outlet of the timing quantitative supply device is provided with a injection port. liquid nozzle. The invention also discloses a method for automatically replenishing electrolyte. The present invention uses a liquid injection nozzle to inject the electrolyte in the electrolyte container into the battery casing arranged in the decompression chamber, and then combines the timing and quantitative replenishment device to fill the electrolyte into the battery, and through the mechanical principle of the lever and the induction switch The combination can realize the timely replenishment of electro-hydraulic dosage and the reliable output of early warning or automatic replenishment of electric control signals. It is simple and easy to implement, cost-effective and reliable in function.

Description

technical field [0001] The invention relates to an automatic electrolyte replenishment method for injecting electrolyte into a battery case. Background technique [0002] A generalized lithium-ion battery (hereinafter referred to as a lithium battery) is mainly composed of a positive electrode, a negative electrode, a separator between the positive and negative electrodes, and an electrolyte. Among them, the separator separates the positive and negative electrodes from each other and does not touch each other. At the same time, the separator has a lot of tiny pores, which allow the electrolyte to circulate between the positive and negative electrodes. The amount of current that a lithium battery can supply is limited by the "capacity" of the lithium battery, and the capacity of the lithium battery is closely related to whether the electrolyte it contains is sufficient. [0003] The task of the electrolyte in the battery is mainly to transfer the charge through the migratio...

But still can't achieve automatic injection

Moreover, due to the different technical levels of personnel and other reasons, the batteries produced are often uneven.

Not only affects the efficiency of production, but also affects the quality of products
