Problems solved by technology

Gradually, some manufacturers make simple thickening tanks and connect them to the reactor so that the materials overflow from the simple thickening tanks. Since there is no stirring in the thickening tanks, it can play a role in settling particles, which can reduce the loss of particles and properly increase the solid content in the reactor. But the yield of this method is still not good, and the reaction time is long

Embodiment Construction

[0012] like figure 1 As shown, a rapid synthesis device for the precursor of the positive electrode material of a ternary lithium battery includes a reactor and a thickener. The reactor has an overflow port, and the overflow port communicates with the thickener. The pump is connected to the reaction kettle, and there is a filter rod in the thickener. The filtrate collected by the filter rod is connected to a vacuum buffer tank through a flow meter and a pneumatic valve. The upper part of the vacuum buffer tank is connected to the vacuum pump, and the bottom is connected to the filtrate storage tank.

[0013] When the negative pressure system of the thickener fails, the pump from the reaction kettle to the thickener can be started, and the slurry in the kettle can be pumped into the thickener through the pump for positive pressure filtration.

[0014] During specific implementation, feed materials into the reactor, and the liquid level in the reactor rises to the overflow port,...

Abstract

The invention belongs to the field of battery material manufacturing and particularly relates to a rapid synthesis device for a ternary lithium battery cathode material precursor. The rapid synthesis device comprises a reaction kettle and a thickening device; an overflow hole is formed in the reaction kettle and is communicated with the thickening device; the bottom of the thickening device is connected with the reaction kettle through a circulation pump; a filter rod is arranged in the thickening device; mother liquor which passes through the filter rod passes through a flowmeter and a pneumatic valve and is connected with a vacuum buffer tank after gathering; the upper part of the vacuum buffer tank is connected with a vacuum pump; and the bottom of the vacuum buffer tank is connected with a mother liquor storage tank. The rapid synthesis device can have the thick strengthening effect, greatly increases the synthetic ternary flow rate, accelerates the reaction speed and improves the yield at a synthesis stage, and thus increasing the yield and lowering the cost.

Description

technical field [0001] The invention belongs to the field of battery material manufacturing, and in particular relates to a rapid synthesis device for a precursor of anode material of a ternary lithium battery. Background technique [0002] Nickel-cobalt-manganese hydroxide is the precursor of the positive electrode material of the ternary finished battery (nickel-cobalt-manganese oxide). The ternary lithium polymer battery is low in cost, high in gram capacity (>150mAh / g), and the working voltage is the same as that of the existing electrolyte. Matching, good safety, excellent circulation, high gram capacity and other advantages. It is now widely used in small electrical appliances, electric tools, electric vehicles and other fields. The nickel-cobalt-manganese hydroxide synthesis process mostly uses an independent reactor for reaction. During the reaction process, before the particle size reaches the standard, the material directly overflows from the overflow port and ...
