<P>PROBLEM TO BE SOLVED: To provide an electrode sheet having a heat-resistant layer integrated therewith for a nonaqueous secondary battery, which has excellent heat resistance and exoergic control function and further can improve durability of a battery. <P>SOLUTION: The electrode sheet for the nonaqueous secondary battery is provided with an active material layer containing a positive electrode active material or a negative electrode active material, and a heat-resistant porous layer which is laminated on the active material layer and contains a heat-resistant resin. In the heat-resistant porous layer, an inorganic filler consisting of a magnesium hydroxide powder with an average particle size of 0.01-3.0 μm and a specific surface area of 1.0-100 m<SP>2</SP>/g is contained. <P>COPYRIGHT: (C)2011,JPO&INPIT |
