Freestanding, heat resistant microporous film for use in energy storage devices |
| abstract |
In a preferred embodiment of a free-supported heat-resistant microporous polymer film 10 that is intended for use in energy storage devices 70, 100 to allow one or more of the following approaches to provide mechanical and dimensional stability at high temperatures, ) Into a porous polyolefin film which is an inorganic or ceramic filler material 16 having a sufficiently high load level to obtain low heat shrinkage; Using crosslinkable polyethylene to crosslink the polymer matrix (14) in a highly filled polyolefin film with an inorganic material; The polyolefin film, which is highly charged with the inorganic material biaxially stretched above the melting point temperature, is heat treated or annealed to maintain the high porosity while keeping the residual stress low. The embodiment of this free-supporting heat-resistant microporous polymer film exhibits a fairly low resistance, which is demonstrated by the number of muscular fibers below 4.5. |
