Description

Technical Field

[0002] Lithium-ion battery electrolyte is the carrier of ion transmission in lithium batteries, generally composed of lithium salt and organic solvent. The commonly used lithium salt in the electrolyte is LiPF6, and the solvent is a binary, ternary or multi-component system composed of a mixture of cyclic carbonates and chain carbonates.

[0003] For example, in a batching device for lithium-ion battery electrolyte with authorization announcement number "CN220176557U", the spiral blades rotate to drive the material solution from bottom to top, the rotating shaft drives the stirring frame to rotate to stir the inner side of the spiral blades, and the stirring frame separates and breaks up the raw materials, so that the whole device can transmit the solution from bottom to top during stirring, and can also quickly break up the raw materials, which can promote the rapid up and down rolling and mixing of the solution inside the stirring tank. However, when the batching device for lithium-ion battery electrolyte stirs and mixes the lithium-ion battery electrolyte, the device only stirs and mixes the ingredients through the spiral blades, and can only perform separate stirring and mixing work.
