Turn on the power switch of the electrode rolling press machine, and wipe the steel roller with alcohol dipped in the dishcloth.The requirement before turning on the equipment are as follows. 1. Check the emergency stop switch to maintain the access state before turning on the power 2. The surface of the steel roller to dry.clean.no oil and particles. Adjust the gap of the steel roller,different battery mode had different roller press parameter,and we don’t bat around at here,but should notice the roller press stroke,avoid the lock phenomenon of the servo motor. Take suitable electrode roller press,verification the gap of the steel roller the requirement is as follow: 1. Steel roller gap adjust to process requirement range. 2. Keep the balance of the electrode and the micrometer. Put the roll materials onto unwinding shaft,adjust it to suitable position,fix it and put the electrode between the two roller,requirement:the electrode should parallel of the front and rear,couldn’t side mounted the electrode on the air,and could not oblique. Turn on the tension system and auto rectify system before roller press,and notice adjust the tension,could not too tight or too loosen,after adjust the tension should confirm it with the process and quality. On the electrode roller press process,weight requirement is as follow: 1. Should notice the vertical of the electrode and micrometer. 2. Keep same of the hand move speed and the electrode move speed. After materials roller press should wipe the surface of the roller,use anti-rust oil wipe the surface of the roller after the waste out. At last it is batter use different equipment to roller press cathode and anode,if don’t have two roller press machine and must use one roller press machine to dispose both of cathode and anode,you must clean up the roller. And the electrode will have the water after roller press,should put it into the oven and baking it.

Because the special situation of this year,we could not go to the side of our customer,so some of the customer would like to have a video chat with us and debug inspection the machine together with us. Today we had finished a total process of the glove box from factory out until use condition:Install component of glove box like water analyzer oxygen analyzer,then purging,regenerate and a serials operate.And finally after we achieve the requirement of the water and Oxygen,less than 0.01ppm,our customer really satisfaction. Super pure purification glove box is a important equipment for our lab battery making,because of some raw materials of the battery is could not connect Oxygen like Li metal and electrolyte.And after our electrode absorb water will also influence the performance of the battery.The battery making process should rigid control the humidity and oxygen concentration. For the glove box,if you dont need a serious control of the condition,we also have the organic glass type and without water oxygen control if you need.And also have HEPA filter type glove box.Of course,if single station is not enough for you and you need mult-station glove box,we can also provide,and these single station glove box is also can disassemble convenience for add another other additional glove box.

When lithium battery cathode surface discharge, the lithium ions in the hole into the cathode active materials. If the current increase the polarization increases, the discharge is difficult, and the conductivity between the electronic is poor, the electrical conductivity of the active substance by itself is not sufficient, in order to ensure good charging and discharging performance of the electrode, a certain amount of conductive agent is usually added in the preparation of the electrode to collect the microcurrent between the active substances and the fluid. As the conducting agent materials for lithium ion batteries, conventional conducting agents super-P, KS-6, conductive graphite, carbon nanotube, graphene, carbon fiber VGCF and so on are mainly used. These conducting agents have their own advantages and disadvantages. 01:SP At present lithium ion battery conductive agent or conventional conductive agent SP. Carbon black has better ionic and electronic conductivity, because carbon black has a larger specific surface area, so it is conducive to the adsorption of electrolytes and improve the ionic conductivity. In addition, carbon particles agglomerate to form a branched chain structure, which can form a chain conductive structure with the active material, which is helpful to improve the electronic conductivity of the material. 03: CNT conductive agent The application proportion in high-end digital battery field is as high as more than 50%, while the application proportion in power battery field is relatively low. However, in recent years, with the improvement of energy density, multiplier performance, cycle life and other performance requirements of power batteries, the proportion of CNT conductive agent in this field is gradually increasing.

According our customer suggestion and requirement,and with our engineer hard working,now we finally made a new design battery stacking machine. This new design battery electrode stacking machine had add two main function. 1. We add the calibration tail used for the electrode calibrate, and have the baffle to position the electrode, which can improve the precision of the machine. Can ensure the electrode can accurate drop down on the center of the stacking plate and ensure the alignment of the electrode side.And the size of the battery can change by yourself. 2. And now we have a new function of the single step, which means we can stacking the electrode 1 layer by 1 layer if you want.After we change the mode to single step mode, after we started the machine and press the foot switch and the sucker will suck a anode electrode,and carry it to the center of the stacking plate,and then carry another cathode electrode to the center of the stacking plate.Easily to debug the machine. To compare with the battery winding process, the battery which made by the stacking have small inner resistant. but have low effective.

Today we have a lot of battery electrode that need to delivery to our Russia customer,whose battery process is also provide by us.a 72Ah big prismatic battery. The process of the electrode making is mainly include battery slurry mixing,battery coating,and battery electrode roller pressing and slitting. The most important parameter of the battery electrode is the area density,thickness and the width. For the area density is controlled by the battery coating machine,and the area density is a parameter that will influence the capacity of the battery.So,a good battery coating machine is important for battery making,which can give us a good electrode with high uniform,no impurity bubble and other coating flaw.And the thickness is depend on the battery materials system and the roller press,if the compaction density is big,there could fill in more electrode in the battery case,but also will influence the rate performance.Of course,the width of the electrode is controlled by the battery electrode slitting machine,a good slitting machine can provide you the smooth cut without rag and powder. Of course,all of these things we can also supply,include the electrode,battery coating machine, battery roller press machine and battery slitting machine and also the battery process knowledge.
