Embodiment 1

[0028] This embodiment includes a drying cylinder 3, which is detachably connected to the pipeline. After the drying of the cells in the drying cylinder is completed, the movable drying cylinder is docked with the glove box for the next liquid injection operation.

[0029] In order to realize seamless docking, a barrel cover 4 is provided on one side of the drying cylinder 3, and a sealing ring is also provided on the barrel cover. The side of the glove box 1 that can be docked with it is provided with a protruding transition chamber 2, and the transition chamber 2 is connected to the barrel. The cover 4 is engaged to realize the seamless connection between the drying cylinder 3 and the glove box 1 .

[0030] When the system of the present invention was working, the compressed air input pipeline 12 delivered to the system from the outside entered the moisture drying treatment device 5, and the moisture present in the external compressed air was dried and processed in the moist...

Embodiment 2

[0041] The above-mentioned embodiments only express the implementation manner of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, such as selection changes of the transmission modulation processing circuit and the reception processing circuit, etc., all of which are Belong to the protection scope of the present invention.

Abstract

The invention relates to the technical field of baking equipment of battery cores, and in particular to a drying system for lithium ion battery cores, which comprises a drying barrel for drying the battery cores to be dried. A pipeline capable of forming circulation drying air is connected onto the drying barrel, a moisture drying processing device and an air heating device are sequentially connected onto the pipeline, an outer compression air input pipeline is connected onto the moisture drying processing device, an inlet regulating valve is arranged on an inlet pipeline connecting the drying barrel and the air heating device, an outlet regulating valve is also arranged on an outlet pipeline connecting the drying barrel and the moisture drying processing device, and dry air used by dry battery cores are circulated back to the drying barrel after passing through the moisture drying processing device and the air heating device. The drying system for lithium ion battery cores recycles the dry air, and can volatilize moisture in the battery cores in time, enables the energy recycling degree to be high, facilitates reduction of drying energy consumption, and reduces manufacture cost.

Description

[0001] technical field [0002] The invention relates to the technical field of preparation of lithium-ion secondary batteries, in particular to the improvement of baking equipment for electric cores in the preparation process. Background technique [0003] Compared with traditional secondary batteries such as lead-acid batteries and nickel-metal hydride batteries, lithium-ion secondary batteries have an incomparable superior performance and shape processing performance, and have been widely used in mobile phones, notebook computers, PDAs, video cameras, digital cameras , Mobile DVD, MP3, MP4 and other mobile electronic terminal equipment, while lithium-ion batteries are also used as power sources for electric tools and electric bicycles. As a new generation of green and environmentally friendly power, lithium-ion batteries are developing rapidly and have become one of the hot spots in international electrochemical research. [0004] In the manufacturing process of batteri...
