Supercapacitor high power high cycle single-sided film pole piece

      High performance electrode is the core technology of supercapacitor manufacturing, which has a decisive impact on the performance of supercapacitor. The film electrode produced by aft is different from the conventional wet electrode and dry electrode preparation process. It adopts all solid-state film-forming technology to produce super capacitor electrode sheet with strong adhesion, high compaction and low moisture content. It is suitable for preparing super capacitor products with low internal resistance, high power, low self discharge and long cycle. Compared with similar products of international famous brands, its capacity is more than 13%, The internal resistance is lower than 15%, the cost is lower than 20%, and the cycle life is longer. Aft can produce pole pieces of different specifications according to the customer's demand, and has realized batch supply in the industry.
Product advantages:
1. Graphene modified materials
2. Low moisture content and good processability
3. Direct film forming technology, strong adhesion, high compaction, large capacity
4. Good cycle, high power density, low self discharge, durable

Super capacitor assembly and basic electrical performance comparison

Super capacitor assembly and basic electrical performance comparison

With the same winding pole group diameter, the average capacity of the AFT-GL pole piece capacitor sample is about 13.6% lower than that of the AFT-RL pole piece sample.
The self-discharge of AFT-RL pole piece capacitors is relatively large in 24 hours, which is 100% higher than the average value of AFT-GL pole piece capacitors
Due to the thin thickness of the two pole piece samples, the ESR value is relatively low. Among them, the ESR of the AFT-GL pole piece capacitor sample is about 10.7% higher than that of the AFT-RL pole piece sample.

Storage requirements
Temperature: -40℃~60℃; relative humidity: 65%RH Max.; shelf life is 12 months;
Precautions
a) There should be temperature and humidity control during the assembly process. It is recommended that the temperature is 20±5% and the humidity is ≤10% to avoid the pole piece from absorbing water and affecting performance;
b) After opening the package, the pole piece should be hung on the shelf to avoid scratches, creasing, wrinkles and other damages;
c) When storing the packaging box, keep it away from light to avoid aging and damage of the vacuum packaging bag;
