Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery production technology, specifically to a conveying device for lithium-ion battery electrolyte. Background Technology

[0002] Lithium-ion batteries have advantages such as high energy density, long cycle life, and no memory effect, and are widely used in smartphones, laptops, electric vehicles and other fields. In the production process of lithium-ion batteries, electrolyte injection is a key step that directly affects the performance and quality of the battery.

[0003] In existing lithium battery filling machines, the electrolyte delivery device mainly consists of an electrolyte raw material tank, a connected high-pressure inert gas device, a delivery pipeline, and an electrolyte delivery tank. During operation, the electrolyte in the raw material tank flows along the delivery pipeline to the electrolyte delivery tank under the propulsion of the high-pressure inert gas. However, this delivery method, which uses high-pressure gas as a power source, causes a large amount of gas to dissolve during the delivery process. When too much gas is mixed into the electrolyte, dripping is likely to occur in subsequent delivery and filling stages. This not only wastes electrolyte but also affects production efficiency and product quality. Furthermore, the gas may carry impurities into the electrolyte during dissolution, further reducing the purity of the electrolyte. Electrolyte purity plays a crucial role in the electrochemical performance of the battery, and the presence of impurities will seriously affect key performance indicators such as battery charge-discharge efficiency and cycle life, failing to meet current requirements.
