Document Type and Number:
Japanese Patent JP2007188777
Kind Code:
A
Abstract:
To provide a separator which prevents battery property deterioration, and a nonaqueous electrolytic solution battery.
A separator 4 has a structure where a resin layer 4a is provided on a principal surface of a base material layer 4b. The resin layer 4a is a matrix resin layer which contains supported inorganic materials and is rich in porosity. This resin layer 4a with inorganic materials supported in the matrix resin gives oxidation resistance to prevent the deterioration of the separator 4.
