<P>PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery and a control method thereof which can effectively improve durability against high rate discharges. <P>SOLUTION: A nonaqueous secondary battery according to the present invention comprises: a wound body 20 with a first electrolyte impregnated therein; resistance measurement means 16 which measures the internal resistance value of the wound body; and a microcapsule 26 which, when the resistance value exceeds a prescribed threshold, supplies a second electrolyte having higher concentration than the first electrode to the inside of the wound body 20. The threshold is a resistance value at such a point that, when a cycle test consisting of repeated charges and discharges is executed in the nonaqueous secondary battery using the first and the second electrolytes respectively as electrolytes, the relative magnitude of resistance values is reversed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
