1. large liquid absorption capacity, liquid absorption speed block, good water permeability, absorbing and maintaining the electrolyte of the rated original capacity of the battery.
2. Large surface area and high porosity, even if the electrolyte is poor, it can ensure that the oxygen generated at the positive electrode can diffuse to the negative electrode through the spacer and combine with the sponge lead on the pole plate.
3. Small pore size can effectively prevent short circuit of the battery.
4. High chemical purity, does not contain any self-discharging impurities
5. Excellent acid resistance and oxygen resistance.
6. Low resistance.
