Microporous membrane and battery separator |
| abstract |
(57) [Abstract] [Problem] A microporous membrane whose electric resistance changes with temperature, As a use thereof, in particular, a separator for a secondary battery that exhibits a shutdown function in which the electric resistance rises from a relatively low temperature to two stages in response to a rise in temperature, and thus has improved safety compared to conventional separators Is to provide. A microporous membrane according to the present invention is obtained by impregnating the membrane with an electrolytic solution and measuring the electrical resistance while increasing the temperature at a rate of 10 ° C./min. It is characterized in that a temperature rise of 10 ° C. or more is required until the electric resistance reaches 1.5R to 10R, and then the electric resistance reaches 10R to 100R within a temperature rise of 5 ° C. or less. |
