Abstract
The utility model discloses a microporous base material which comprises a metal foil, a first coating layer and a second coating layer, wherein a plurality of micropores are formed in the metal foil; the first coating layer is positioned on the upper surface of the metal foil; the second coating layer is positioned on the lower surface of the metal foil; and the first coating layer and the second coating layer are bonded with the metal foil through the micropores. According to the microporous base material, the micropores are formed in the metal foil, so that the coating layers can be bonded with the metal foil through the micropores, the strength of bonding between each coating layer and the metal foil is enhanced, active substances cannot be locally separated from a substrate after the coating layers are cycled for multiple times, and the battery life is prolonged; moreover, the formed micropores are three-dimensional micropores, so that the thickness of the base material is increased, the usage amount of the base material and an isolating membrane is correspondingly reduced, and the manufacturing cost of a battery is lowered; and meanwhile, the micropores in the base material form passages for facilitating liquid filling and electric liquid infiltration, so that the conductivity of the battery is improved.
