Japanese Patent JP7041426
Kind Code:
B2
Abstract:
To increase the safety and endurance of a nonaqueous secondary battery.SOLUTION: Provided is a nonaqueous secondary battery separator which comprises: a polyolefin porous base material; and a thermally resistant porous layer laminated on one or each face of the porous base material. In the nonaqueous secondary battery separator, the thermally resistant porous layer contains a thermally resistant resin, and a fluorine-containing magnesium hydroxide represented by the formula below (Formula 1) and satisfying the items (A) and (B) below. MgF(OH)(Formula 1) (where x falls in a range given by 1
