Description
Technical field
The utility model relates to a kind of dividing plate, specifically a kind of colloid battery separator.
Background technology
Battery comprise the dividing plate between anode and negative electrode and prevent anode and negative electrode between short circuit, can be short-circuited when this dividing plate of conductive particle bridging or dividing plate are deteriorated to while allowing electrode contact.Effectively battery separator should be under the various electrolytical existence existing in battery chemically stable, physics is durable and freely allow ion to flow in whole battery.On battery separator, be distributed with some holes, electrolyte can be circulated, dividing plate mesopore rate is higher, and colloid permeability is larger, and battery efficiency is higher, and at present, the porosity of existing battery separator is generally on the low side, the requirement that cannot be up to state standards.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of colloid battery separator efficiently, and its porosity is high, and efficient excellent energy significantly improves the electric property of colloid battery.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of colloid battery separator efficiently, comprise substrate, wherein, the thickness of described substrate is 0.28-0.5mm, described substrate is provided with some through holes, the porosity > 60% of described through hole, described through hole comprises through hole and lower through-hole, between described upper through hole and lower through-hole, be connected by interface channel, described upper through hole is pyramidal structure, its cross sectional shape is right-angled trapezium, the upper base length L 1=2* of the right-angled trapezium that described upper through hole cross section the is length L 2 of going to the bottom, and its hypotenuse is curved, the medial surface that is described upper through hole is sphere, described lower through-hole is pyramidal structure, its cross sectional shape is isosceles trapezoid, the length L 2 of going to the bottom of the right-angled trapezium that the upper through hole of the upper base length L 3=cross section of the isosceles trapezoid that described lower through-hole cross section is is, the upper base length L 1 of the right-angled trapezium that described in length L 4 < that go to the bottom of the isosceles trapezoid that described lower through-hole cross section is, upper through hole cross section is, the height H 2 of the height H 1=2* lower through-hole of described upper through hole, described interface channel is cylindrical structural.
The efficient colloid battery separator of above-mentioned one, wherein, evenly reduce to center at the interior two ends without leave of described interface channel.
The beneficial effects of the utility model are:
The utility model substrate is provided with through hole, and the porosity > 60% of through hole, this porosity is much larger than 55% of national standard requirement, because porosity increases, resistance in colloid battery reduces, the permeability of colloid significantly increases, therefore all electric properties of colloid battery are all greatly improved;
Through hole comprises through hole and lower through-hole, and the shape setting of upper through hole and lower through-hole makes electrolyte osmosis more smooth and easy, has improved the efficiency of battery;
The thickness of substrate is 0.28-0.5mm, has increased the intensity of this colloid battery separator, has increased useful life.
