Number mainly has aperture, porosity etc..The aperture of micropore foil is the important indicator for evaluating micropore foil performance, because of micropore foil aperture pair
The filling of electrode active material has a great impact.
Aperture is too big, then electrode active material heaps serious, and the electric conductivity of usual electrode active material is poor, to make electricity
Pole internal resistance increases, and electrode active material utilization rate reduces, and influences the chemical property of entire device；Aperture is too small, electrode activity
Substance is not easy to fill, and is focusing only on electrode surface, cannot make full use of the advantage of micropore foil.In addition, micropore foil aperture size is also
Influence the cementability of electrode active material and collector.Therefore, when the aperture of micropore foil is larger, slurry is easy to miss.Research
Show that micropore foil can improve the ability that electrode collects electric current, i.e. power density when the diameter of perforated foil is less than 100 μm, this
Outside, moreover it is possible to improve device energy density and interior resistance, but the influence very little of the internal resistance of micropore foil aperture size at this time,
It can ignore.
For lithium ion battery, volume, quality are the smaller the better, and the higher the better for energy density, power density.In general,
Micropore foil porosity is higher, and the electrode active material that collector accommodates is more, to improve the energy density of lithium ion battery.
In addition, porosity is bigger, micropore foil is that the volume cushion space that electrode material provides is bigger, is glued between electrode material and collector
Connect more secured, the cycle performance of lithium ion battery is better, and service life is longer, while achieving the purpose that improve efficiency for charge-discharge.
