| 摘要 |
The present invention is directed toward a laminated electrode and porous separator film combination including a solid electrolyte salt within the porous separator film, the combination comprising layer of powdered cathode material adhering to a surface of a separator film with a solid electrolyte therebetween; the separator film comprising 50% to 95% by weight of electrically non-conductive ceramic fibers having a coating of magnesium oxide on the surface of the fibers in an amount in the range of 5% to 50% by weight; wherein the ceramic fibers comprise Al2O3, AlSiO2, BN, AlN, or a mixture of two or more of the foregoing; and the magnesium oxide coating interconnects the ceramic fibers providing a porous network of magnesium oxide-coated fibers having a porosity of not less than 50% by volume; the pores of the network containing a solid electrolyte salt in an amount of up to 95% by volume based on pore volume of the network.
