Lithium-ion battery aging device and aging method

Abstract

The invention discloses a lithium-ion battery aging device and aging method. The aging device includes a box body, a separator, a drying tool, a high-pressure steel cylinder, a heating blower, a battery fixing clip and an aging box; the box body is connected to a gas pipeline, The gas pipeline is connected with a drying tool and a heating blower in series; the gas pipeline is connected with a high-pressure steel cylinder through the first bronchus between the drying tool and the inlet end of the box; the battery clamp is used to clamp the battery; the aging box Used to place battery clips and age batteries. The present invention can make full use of the heating heat when the battery is aging, and will not cause a large loss of energy, and when heating, the battery is heated evenly and the temperature changes steadily and slowly, which effectively improves the aging quality of the battery. The fire prevention ability of the present invention It is strong and can quickly extinguish the fire without opening the box, which is safe and fast, and improves the operating safety of the staff.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a lithium-ion battery aging device and aging method. Background technique [0002] Since the commercialization of lithium-ion battery materials by Japan's Sony Corporation, lithium-ion batteries have rapidly become popular in portable batteries due to their light weight, high voltage, small size, no memory effect, high specific energy, long cycle life, and environmental friendliness. Portable power supplies, mobile phones, laptops, cameras and other portable electronic products are popularized and applied, and occupy an important position in the energy field. [0003] In the production process of lithium-ion batteries, it is necessary to go through the aging process. The aging process is generally carried out after the formation and sealing. The aging of lithium-ion batteries can fully infiltrate the electrolyte, and at the same time, the active components of the p...

AI Technical Summary

Problems solved by technology

In the prior art, the aging of the battery is generally accelerated by baking the battery under high temperature conditions. However, when the battery is baked, on the one hand, due to the thick shell of the battery itself, when the battery is baked at high temperature, Due to the uneven aging temperature, the large temperature change in the baking room will lead to poor aging effect of the battery, and the high local temperature of the lithium-ion battery during the aging process will also cause serious consequences such as battery damage or even fire. The defective rate and production cost of lithium-ion battery production

[0004] Lithium-ion batteries in the prior art are put into the baking chamber or oven most directly when they are aging. This method will waste a lot of energy due to the heat absorption of the battery case, and because batches of batteries are placed Together, when a fire breaks out, it is easy to cause the expansion of the disaster range, thereby increasing the risk of production and disaster losses. In order to solve these problems, the present invention provides the following technical solutions
