Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery electrolyte additive processing, and more specifically to a lithium ion battery electrolyte additive dehydration device. Background Art

[0002] With the development of modern society and the enhancement of people's environmental awareness, lithium-ion batteries are gradually replacing lead-acid batteries and nickel-hydrogen batteries, and developing into the main alternative power source in the 21st century. For lithium-ion batteries, especially large-scale power lithium-ion batteries used in electric vehicles and energy storage devices, the factors that currently limit their further application are mainly the battery's cycle performance and safety performance, and one of the main factors affecting battery performance is the water content.

[0003] The existing lithium-ion battery production process requires moisture control. During the use of conventional processes, due to the large amount of organic solvents used and the low viscosity of the materials, the moisture content will be reduced after 5A molecular sieve circulation dehydration and filtration treatment. Functional additives will improve certain functions of the battery such as circulation, high temperature, low temperature, rate, etc., but they are not easy to dehydrate. In response to the situation in the market, it is necessary to accurately absorb moisture during the production of lithium-ion batteries, and ensure that the material loss is as small as possible during the dehydration process, and ensure that the dehydration time is reduced. In view of this, we propose a lithium-ion battery electrolyte additive dehydration device. Utility Model Content
