Technical field
The utility model relates to the process units in a kind of lithium ion battery field, especially relates to a kind of polyalcohol lithium ion battery afflux liquid device of coating continuously.
Background technology
Along with the development trend of the miniaturization of portable electric appts, frivolous polymer Li-ion battery is widely used just day by day.General polymer Li-ion battery is usually by forming by the stacked anode of hot pressing mode, negative electrode and the barrier film that is clipped in wherein.In order to be connected with external circuit, the mode that anode, negative electrode usually will be by hot pressing is attached to anode collector, on the cathode current collector.In order to improve the conductive effect of negative electrode, anode collector, and the adhesive force between negative electrode, anode and collector, need that the collector coating of target, anode is a kind of caking property, a net slurry that conductive effect is good.
But the surface of slurry attached to the anode and cathode collector will net by spray gun by at present a lot of manufacturers, and production efficiency is low, and the utilization rate of net slurry is about 10%, and the thickness of spraying is difficult to control, and influence the electrical property of battery.
Though the domestic surface treatment method that various collectors have been arranged does not have the surface processing device of supporting collector, therefore good again method and technology also can fall behind because of the technology when the coating, and advanced technology is had a greatly reduced quality.
Be the surface treatment method of 00117142.9 affluxion body in lithium ion batteries as a kind of domestic patent No., his technical characterictic is: the copper ammon solution with 1%-5% concentration carried out Passivation Treatment 5-20 minute the affluxion body in lithium ion batteries surface; With the dichromic acid aqueous solution of 5-20% concentration to the further Passivation Treatment 1-5 of affluxion body in lithium ion batteries minute; Treat on the maxxaedium coupling agent of coating 0.5-1.5% at affluxion body in lithium ion batteries, 80-150 ℃ dry 20-100 minute down; The anhydrous cupric sulfate of preparation copper ammon solution and the mol ratio of ammoniacal liquor are 1: 2; Coupling agent is gamma-aminopropyl-triethoxy-silane or γ-propyl methacrylate base trimethoxy silane.
Summary of the invention
The utility model mainly is at existing in prior technology in use, problems such as net slurry coating utilization rate is low, provide a kind of rational in infrastructure, can improve the utilization rate of net slurry, make it reach 95% with the continuous device that is coated with of the polyalcohol lithium ion battery afflux liquid of first-class advantage.
Problems such as the utility model has also solved in the prior art simultaneously, and it is even to net the slurry crawling, and thickness is uncontrollable provide a kind of net slurry coating homogeneous, can control the device of the continuous coating of polyalcohol lithium ion battery afflux liquid of thickness
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: collector is successively respectively by unwinding device, apparatus for coating, baking oven, wrap-up, there is apparatus for coating the baking oven below, and unwinding device and wrap-up are separately positioned on the both sides of baking oven.
As preferably, described apparatus for coating is a roller coating device; Because roll coating model has been adopted in coating, has both guaranteed the coating effect, and, can control coating thickness by adjusting corresponding technological parameter.
As preferably, described roller coating device is that two sections identical application roll of shape are formed side by side; Width between it can be regulated is controlled the thickness of coating.
As preferably, unwinding device is that several rollers are formed, and collector contacts with roller one side.
As preferably, wrap-up is that several rollers are formed, and collector contacts with roller one side.
As preferably, in the baking oven of described collector positioned vertical; Collector is vertically by baking oven, so that drying course is even, stable.
As preferably, described apparatus for coating be positioned at baking oven under; After coating finished, collector directly vertically entered baking oven.
As preferably, a roller of described wrap-up be positioned at baking oven directly over; In order to stretching collector.
Therefore, the utlity model has characteristics such as mould structure is simple, reasonable, easy to use, both improved production efficiency, improved the utilization rate of net slurry again, it is reached more than 95%, coating effect homogeneous is significantly improved the charge-discharge performance of battery and cycle performance, and the thickness of net slurry coating can be controlled in the scope of technological requirement.
