20110308727 | Partially Crosslinked Adhesive-Supported Porous Film for Battery Separator and its Use - A partially crosslinked adhesive-supported porous film for battery separator, which in producing a battery, can effectively produce a battery as an electrode/separator laminate in which an electrode and a separator are temporarily bonded to each other without causing mutual slip movement between the electrode and the separator and which after producing a battery, functions itself as a separator having a small heat shrinkage factor even at high temperatures, and a process of producing a battery using such a partially crosslinked adhesive-supported porous film. The partially crosslinked adhesive-supported porous film for battery separator, includes a porous film substrate having supported thereon a partially crosslinked adhesive that is partially crosslinked by preparing a reactive polymer having a functional group in the molecule and capable of being crosslinked upon reaction with a polyfunctional compound having reactivity with the functional group and then reacting the reactive polymer with a polyfunctional compound. | 12-22-2011 |
20130004654 | REACTIVE POLYMER-SUPPORTED POROUS FILM FOR FOR BATTERY SEPARATOR, METHOD FOR PRODUCING THE POROUS FILM, METHOD FOR PRODUCING BATTERY USING THE POROUS FILM, AND ELECTRODE/POROUS FILM ASSEMBLY - A reactive polymer-supported porous film for separator, that has sufficient adhesiveness between electrodes and separator and can suitably be used to produce a battery having low internal resistance and high rate performance, a method for producing the porous film, a method for producing a battery using the porous film, and an electrode/porous film assembly are disclosed. The reactive polymer-supported porous film for battery separator includes a porous film substrate having supported thereon a reactive polymer obtained by reacting a crosslinkable polymer having at least one reactive group selected from the group consisting of 3-oxetanyl group and epoxy group in the molecule, with an acid anhydride, thereby partially crosslinking the polymer. | 01-03-2013 |
