Problems solved by technology

[0004] However, if the liquid level sensor is used to detect the remaining amount of electrolyte in the container as in the past, it is necessary to install the liquid level sensor installed in the old container to the new container when the container is replaced.
In this way, there will be the following problems: during the replacement operation, the electrolyte solution in the container is in contact with the air, and impurities such as moisture and dust in the air are mixed into the electrolyte solution, causing the performance of the battery to deteriorate.

Embodiment Construction

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings and the like.

[0010] FIG. 1 is a schematic configuration diagram of an electrolytic solution supply device 1 according to an embodiment of the present invention for supplying an electrolytic solution to a battery case of a lithium ion secondary battery. As a battery case of a lithium ion secondary battery, a laminated film package etc. are mentioned, for example.

[0011] The electrolytic solution supply device 1 has a main tank 2, a high-pressure gas tank 3, an auxiliary tank 4, an electrolyte injector 5, a gas supply pipe 6 connecting the main tank 2 and the high-pressure gas tank 3, and an electrolyzer connecting the main tank 2 and the auxiliary tank 4. Hydraulic distribution pipe 7, mass flow meter 8, vacuum chamber 9 and controller 10.

[0012] The main container 2 has a detachable upper cover 21, and the main container 2 stores an electrolytic solution to be su...

Abstract

Disclosed is a device for supplying an electrolyte solution, which is characterized by comprising: a tank which stores an electrolyte solution; a supply-receiving unit to which the electrolyte solution in the tank is supplied; a pipe which connects the tank and the supply-receiving unit with each other; a gas pressure-feeding unit which pressure-feeds an inert gas into the tank so that the internal pressure of the tank is increased, thereby supplying the electrolyte solution in the tank to the supply-receiving unit via the pipe; and a mass flowmeter which is arranged within the pipe and detects the mass flow rate of a fluid that flows in the pipe.

Description

technical field [0001] The invention relates to an electrolyte supply device. Background technique [0002] As a conventional electrolyte solution supply device, Japanese Patent Laid-Open Publication JPH8-236144A describes an electrolyte solution supply device that supplies the electrolyte solution stored in the main tank to the battery tank of the lead acid battery via the auxiliary tank. In this conventional electrolytic solution supply device, a liquid level sensor is provided inside the auxiliary tank, and the remaining amount of the electrolytic solution in the auxiliary tank is detected by the liquid level sensor. [0003] At the bottom of the container for storing the electrolytic solution, solid impurities in the electrolytic solution may be deposited. Therefore, in order not to supply the electrolyte solution containing impurities, it is preferable to replace the old container with a new container to replenish the electrolyte solution when the residual amount of th...
