Technical field
The utility model relates to a kind of coating machine that is used to prepare the anode aluminum foil current collector, especially a kind of battery pole piece coating machine that has the collector purging system.
Background technology
Secondary lithium battery has become the mainstream product in the market gradually, and development prospect is huge.Mainly by cobalt acid lithium, LiMn2O4, LiFePO4 and ternary lithium lining battery, the characteristic of different lithium ion batteries also is not quite similar existing product on the market.LiFePO4 conduct a kind of cell positive material wherein is because its superior charge-discharge performance and low relatively cost of material have become a focus of studying in the lithium ion battery.The chief component of general secondary lithium battery comprises positive/negative plate, barrier film, electrolyte, positive and negative lug and shell, and the selection of each part and preparation and whole assembling can both influence the overall performance of battery.The both positive and negative polarity active material of lithium ion battery is attached on the positive and negative of collector; Secondary charging-discharging lithium ion battery now commonly used generally adopts aluminium foil as plus plate current-collecting body, and Copper Foil is as negative current collector, is because aluminium and copper all have good conductivity, characteristic that ductility is good on the one hand; Be because in lithium ion battery on the other hand; Because voltage is high during anodal the charging, requires the plus plate current-collecting body resistance to oxidation, aluminium foil surface can form the fine and close aluminium oxide of one deck; Protection aluminium foil and active material reaction generate aluminium lithium alloy and cause collector intensity to descend, so present producer generally all uses optical aluminum foil as plus plate current-collecting body.The energy density of pole piece depends on the compacted density of anode pole piece, so the adhesive ability of active material on plus plate current-collecting body has significant impact for the energy density of improving pole piece.The negative electrode active material of lithium ion battery generally is a graphite; The adhesion property that increases graphite can be through adding more additive when pulling an oar; If the adhesion properties of collector itself has been improved; Just can reduce the interpolation of examples of such additives, thereby reduce the thickness of negative plate, and then improve battery capacity.And the tack of collection liquid surface receives dust and dirt possibly, and the influence of surperficial natural oxide layer.In transportation; The dust and the greasy dirt on surface sometimes are unavoidable, and these surperficial dirts can influence cell active materials, no matter be anode sizing agent or cathode size; At the adhesive ability of collection liquid surface, so be an important ring in fact to the cleaning of collection liquid surface.Implement if the cleaning of collector and coating are divided into two steps, not only increased the difficulty of collecting collector, more increased collection liquid surface by the danger of polluting once more.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art; A kind of battery pole piece coating machine that has the collector purging system is provided; Increased cleaning and drying mechanism, reduced the difficulty of collecting collector, reduced collection liquid surface by the danger of polluting once more to collector.
The technical scheme that provides according to the utility model; The said battery pole piece coating machine that has the collector purging system; Comprise the pole piece coating machine; Characteristic is: charging one side at said pole piece coating machine is installed the deionized water rinsing groove, in charging one side of deionized water rinsing groove the ultrasonic acid washing trough is installed, and directly over the deionized water rinsing groove, drying mechanism is installed.
Described ultrasonic acid washing trough and the parallel placement of deionized water rinsing groove.
Feedstock direction in said ultrasonic acid washing trough is installed the collector reel that is used to carry collector, and the tension force roller is installed between collector reel and ultrasonic acid washing trough.
In said deionized water rinsing groove, be equipped with first and carry roller, above the deionized water rinsing groove, be equipped with second and carry roller, in the ultrasonic acid washing trough, be equipped with the 6th and carry roller.
Between said deionized water rinsing groove and ultrasonic acid washing trough, install the 3rd and carry roller, between ultrasonic acid washing trough and tension force roller, install the 4th and carry roller, between tension force roller and collector reel, install the 5th and carry roller.
The utility model improves existing coating machine, has increased cleaning and drying mechanism to collector, has reduced the difficulty of collecting collector, has reduced collection liquid surface by the danger of polluting once more.
