Mixing device for lithium battery electrolyte

Abstract

The stirring device comprises a second servo motor and a third servo motor, stirring blades are symmetrically and fixedly connected to the surface of a rotating rod, the two ends of the rotating rod are symmetrically and rotationally sleeved with rotating sleeve plates, and the opposite faces of the rotating sleeve plates are symmetrically and rotationally sleeved with rotating lead screws; the surface of the rotating screw rod is symmetrically sleeved with rotating sleeve rings in a threaded mode, flow guide mechanisms are fixedly connected to the opposite surfaces of the rotating sleeve rings, sliding blocks are symmetrically connected to the surfaces of the flow guide mechanisms, and one end of the rotating screw rod extends out of one side of the right rotating sleeve plate and is movably sleeved with a belt pulley. According to the mixing device for the lithium battery electrolyte, the problems that when a conventional stirring mechanism is used for stirring, the flowing area of liquid in an inner cavity is not changed, so that lithium salt, a solvent and an additive are not uniformly fused again, and residual materials of the lithium salt, the solvent and the additive appear in the liquid are solved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a mixing device for lithium battery electrolyte. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, so this battery is also called a lithium metal battery. Unlike other batteries, Li-ion batteries have the characteristics of high charge density, long life and high unit cost. According to different structural design and electrode materials, lithium batteries can generate voltages from 1.5V (equivalent to zinc-carbon or alkaline batteries) to 3.7V, where the electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc. (with certain corrosion ), providing ions for their normal work. And ensure that the chemical reactions that occur in the work are reversible. Electrolyte There are many advantages to using electrolyte a...
