Abstract
A nonaqueous secondary battery includes a current cutoff mechanism that cuts off a current in a short period of time in response to a rise in pressure inside a battery outer body in at least one of a conductive path through which a current is taken out from a positive electrode plate to outside of the battery and a conductive path through which a current is taken out from a negative electrode plate to outside of the battery. At least one type selected from an oligomer containing a cyclohexyl group and a phenyl group, a modified product of the oligomer containing a cyclohexyl group and a phenyl group, a polymer containing a cyclohexyl group and a phenyl group, and a modified product of the polymer containing a cyclohexyl group and a phenyl group is present on the surface of the positive electrode plate.
