Membrane film for batteries, having a shut-off function |
| abstract |
The present invention relates to a biaxially oriented microporous film composed of at least two co-extruded layers comprising an outer cut-off layer and another layer, both of the layers comprising a propylene homopolymer and a propylene block A mixture of a copolymer and a beta-neutralizing agent. Propylene block copolymer I of the other layer has a melting point in excess of 140 DEG C and the propylene block copolymer II of the external shutoff layer has a melting range beginning at a temperature of 50 to 120 DEG C and the melting point of the propylene block copolymer I Is higher than the melting point of propylene block copolymer II. |
