Cathode slurry
This is the cathode slurry mixing room. First ,we mix the powder with NMP in the mixing tank .And the NMP is added to the mixing tank in three times. Add more NMP to the mixing tank to adjust the slurry viscosity. Finally, transfer the slurry to the coating line after slurry sifting.
Anode slurry
This is the anode powder process. First, we mix CMC with water in that anode binder mixing room, and after weighing, the raw material is transferred into the mixing tank. Then, we add the anode binder solution to the mixing tank in 3 times. After that, we add the SBR for the final mixing. and then, we add more water to adjust the slurry viscosity. Next we sift the slurry in that sifting room. Finally, we transfer the finished slurry to the coating line.

viscosity  粘性
sifting    筛

Coating
泰国西那瓦大学Now, we are in coating line. We u back rever coating. This is the slurry-mixing tank. The anodeCathode slurry is introduced to the coating header by pneumaticity from the mixing tank. The slurry is coated uniformly on the copper foil, then the solvent is evaporated in this oven. There are four temperature zones, they are independently controlled. Zone one ts at 55 degree C, zone two ts at 65 degree C, zone three ts at 80 degree C, zone four ts at 60 degree C. The speed of coating is 4 meters per minute.
You e the slurry is dried. The electrode is wound to be a big roll and put into the oven. The time is more than 2 hours and temperature is t at 60 degree C.
Throughout the coating, we u micrometer to measure the electrode thickness per about
15 minutes. We do this in order to keep the best consistency of the electrode.

Electrode
After coating we compress the electrode with this cylindering machine at about 7meters per minute. Before compress we clean the electrode with vacuum and brush to eliminate any particles. Then the compresd electrode is wound to a big roll. We u micrometer to measure the compresd electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible internal short. The large electrode with edge taped is slit into smaller pieces. This is ultrasonic process that aluminum tabs are welded onto cathodes using ultrasonic weld machine. We tape the weld ction to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.

Anode making
In anode making process, we cut the nickel roll into certain length strips. At the mean time, we put a small piece of insulation tape to the tab in order to prevent any possible internal short. Then the prepared nickel tab is riveted on anode and pat plain. We also tape the rivet ction to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.
Jelly roll
This is Jelly roll, a manual winding process. In the cour of Jelly roll, firstly, we place the parator in between central pins, press the foot switch to turn central pins about 120 degrees. Secondly, place the anode to the edge of central pins, and turn central pins about 180 degrees. Lastly, place the cathode to the edge of central pins. During the winding process, we apply tension by pressing the electrodes and the parator. We put the termination tape at the end.

After Jelly roll, we check the short circuit, then form the Jelly roll by pressing, so that it is easier to inrt the Jelly roll into the can.
Control points:
1. When winding to the end of the anode, covering the anode completely by the parator.
2. In the whole process, it is the most important points to ensure the best alignment among the cathode, the anode and the parator for the Jelly roll. The parator has to cover the anode and the cathode, and the anode has to cover the cathode completely. The points are mainly checked before short checking.
