Mixing( 配料 ) Mix solvent and bound separately with positive and negative active materials. Make into positive and negative pasty materials after stirring at high speed till uniformity. Coating （涂布） Now, we are in coating line. We use back reverse coating. This is the slurry-mixing tank. The anode（ Cathode） 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. （下面的依据情况而定） There are four temperature zones, they are independently controlled. Zone one sets at 55 degree C, zone two sets at 65 degree C, zone three sets at 80 degree C, zone four sets at 60 degree C. The speed of coating is 4 meters per minute. You see 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 set at 60 degree C. Throughout the coating, we use micrometer to measure the electrode thickness per about 15 minutes. We do this in order to keep the best consistency of the electrode.

Pressing Press the above positive and negative sheets till they become flat. Punching Punching sheets into electrodes according to battery specification, 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 compressed electrode is wound to a big roll. We use micrometer to measure the compressed electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible intern
