Xingbang PVDF diaphragm and other PE, PP, diaphragm paper, stretching membrane comparative advantages

1. High porosity-----The porosity of Xingbang PVDF diaphragm can be controlled to about 65%, which is obviously improved compared with 40% porosity of some products of the same kind. High porosity means: 1 diaphragm permeability Good 2 reduce the impedance when the ions pass, that is, the internal resistance of the super capacitor is small. 3 The opening ratio is high. 4 The liquid absorption capacity is high. 5 The liquid holding ability is strong.

2. Good permeability-Xingbang PVDF diaphragm permeability is also called Gurley number only 8, similar products are generally 300-600, because Xingbang PVDF diaphragm aperture is uniform size and distribution.

3. Good compatibility with electrolytes-performance of higher liquid absorption ability and liquid retention ability

4. Good stability -- 1 Good chemical stability, performance of resistance to organic solvents, corrosion resistance 2 good thermal stability, performance of low thermal shrinkage: 120 °C 10 H thermal contraction ≤ 0.2 %. Thermal stability is more favorable to capacitance security.

5. Automatic shutdown protection function-150 °C for lower hole closing temperature and 172 °C for higher membrane breaking temperature is an effective method to limit capacitance temperature rise and prevent short circuit.

The above comparative advantages of the Xingbang PVDF diaphragm can make the capacitance, lithium battery products more efficient(self-discharge rate ≤ 2 % / month), larger capacity, and better recycling performance.
