The battery formationg machine for pouch cell Vacuum glovebox Battery Materials are packaged up and ready to ship.

1.Test method for anode graphite moisture (1) The weight loss of the sample after baked is the weight of the lost moisture, and the ratio of the reduced weight to the weight of the sample is the weight of the water content of the sample. (2) Instruments and Reagents:Moisture meter(TOB-AKF-CH6), medicine spoon Sample Graphite Powder Instruments and accessories AKF-CH6 Karl Fischer moisture tester 10 ml sample feeding bottle High purity nitrogen 99.99% Electronic balance 0.1 mg Reagent Coulomb method Karl Fischer reagent, made in China Instruction parameter Ventilation flow:30ml/min Heating temperature: 180℃ Electrolytic speed: automatic Mixing speed: 6 Blank deduction: calculation Measure method (1) Turn on the TOB-AKF-CH6 moisture tester and add an appropriate amount of Karl Fischer reagent to the titration tank to ensure that the reagent is between the maximum and minimum scale. (2) Turn on the nitrogen cylinder ,set gas flow ,temperature (3 ) Wait for blank electrolysis balance test of the instrument. (4) For sample testing, take appropriate amount of sample into the sample bottle, place it on the heating tank, connect the heating tracing tube, click start measurement, then sample, input relevant parameters, and wait for the measurement results 2. Test method foranodegraphite tap density (1)Vibrate the graphite contained in the steel cylinder in the tap density tester for 10 minutes, calculate the volume after vibration through its descending depth, and then divide the weight of graphite by the volume after vibration to obtain the tap density. (2)Instruments: powder tap density meter, steel cylinder (with steel cap), medicine spoon, depth vernier caliper, flattener powder tap density meter: You can use  TOB-TDT-JZ-7 Powder Tap Density Tester Email : tob.amy@tobmachine.com Skype : amywangbest86 Whatsapp/Phone number : +86 181 2071 5609

The coating process is often prone to appearance problems, such as dry cracking, streaking, color difference, bulging edge, wrinkling, etc. Among them, wrinkling occurs more frequently and requires high equipment and process parameters. We need to pay attention to the follow process Design phase Predicting and solving coating wrinkle through accurate calculation and digital simulation (1) The diameter, pitch and wrap angle of roller (2) Electrodes speed, tension and deflection angle (3) Temperature, flow direction and speed of air inside the oven, etc. Manufacturing stage (1) Smoothness of the roller surface (2) Manufacturing precision of oven air nozzle; (3) Roll fastening screws. Installation stage (1) The overall installation accuracy of the coating machine; (2) Parallelism between rollers. Commissioning stage (1) Timely cleaning of foreign matter and water on the stick; (2) Poor foil strip joint and unbalanced tension on both sides of the foil strip; (3) The rubber roller surface of the pressure roller will undergo periodic elastic deformation in the course of use, when a certain degree of deformation remains, wrinkling will also occur, at which time the new product must be replaced.

The function and principle of the battery cap (1) Positive or negative terminal (2) Temperature protection function: PTC (sudden increase in resistance, cut off current) (3) Power-off protection function: CID current disconnecting device (Inner pressure rises → Vent flips → CID solder joints break) (4) Pressure relief protection function: Vent (Inner pressure rises → Vent flips → CID solder joints break → pressure continues to rise → Vent ruptures) (5) Sealing function: waterproof, gas intrusion, anti-electrolyte evaporation Key points of cap design (1) Reduce the height of the cap (2) Vent's double-sided notch is optimized to single-sided notch, and Vent's blasting and flipping consistency is better (3) Using duralumin CID application, the Vent notch is not easy to stretch and deform, and its blasting consistency is better  Email : tob.amy@tobmachine.com  Skype : amywangbest86  Whatsapp/Phone number : +86 181 2071 5609
