Problems solved by technology

[0004] The characteristics of the secondary electrolysis are: low precision, micro-quantity, and high efficiency, but there is no professional equipment for filling the secondary electrolyte in the current technical field
The traditional pump type relies on the number of rotations to control the efficiency is low and can only be filled by a single unit at a time. In view of the demand characteristics of the secondary liquid injection equipment, this invention proposes this kind of equipment that can be filled with high efficiency

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] see Figure 1 to Figure 4 As shown, a simple and efficient micro-injection device includes a driving cylinder 1 that provides power. The driving cylinder 1 is connected to the metering tube 2. 4-phase connection, the driving cylinder 1 drives the rubber piston 4 to move in the metering tube 2, thereby completing the suction and discharge process of the electrolyte. The metering tube 2 is made of tempered glass, and its transparent structure can facilita...

Abstract

The invention discloses a simple and efficient trace-liquid injecting device. The simple and efficient trace-liquid injecting device comprises a driving air cylinder. The driving air cylinder is connected with a rubber piston arranged in a metering tube through a connecting rod. The metering tube is communicated with a liquid storage tank. External connection tubes used for delivering electrolytes are arranged on the liquid storage tank and provided with first one-way valves for controlling circulating of the electrolytes. The liquid storage tank is communicated with a liquid distributor, and a second one-way valve for controlling circulating of the electrolytes is arranged between the liquid storage tank and the liquid distributor. The liquid distributor comprises a liquid distributor tube. One or more liquid outlet tubes are arranged on the liquid distributor tube. According to the simple and efficient trace-liquid injecting device, due to air cylinder driving, stroke amount fixing, one-way valve control and special liquid distributor design, the high-efficiency injecting device for liquid such as a trace of electrolytes is provided through the simple structural design, and liquid sucking and the electrolyte injecting process of multiple batteries can be completed through one-time stroke driving.

Description

technical field [0001] The invention relates to the field of lithium battery preparation, in particular to a simple and efficient micro-volume liquid injection device. Background technique [0002] Since the birth of lithium-ion batteries, with the continuous advancement of technology, its performance has been significantly improved compared to before. As far as the current chemical secondary power source is concerned, it has an irreplaceable role, especially with the advent of the energy crisis and the increasing environmental pressure, the market demand for lithium-ion battery applications is increasing, and it has been used as a power source for electric vehicles field. As the power source of electric vehicles, lithium-ion batteries face performance pressures such as high capacity and high power density. [0003] With the increasing demand for volume energy density of lithium-ion batteries, materials and processes are constantly improving. However, for a material, the i...
