COLLECTOR FOR BIPOLAR SECONDARY BATTERY, BIPOLAR SECONDARY BATTERY, BATTERY PACK, VEHICLE, CONTROLLER FOR BIPOLAR SECONDARY BATTERY, AND CONTROL METHOD FOR BIPOLAR SECONDARY BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide a collector for a bipolar secondary battery which suppresses extraction of currents from the bipolar secondary battery to reduce heat generation from the battery. PSOLUTION: The collector 11 is for use in the bipolar secondary battery 10 including a first electrode 13 on a first face and a second electrode 15 on a second face opposite to the first face, the second electrode being different in polarity from the first electrode 13. The collector 11 has a first conductive resin portion 71 whose electric resistance increases when a battery temperature rises to reach a given temperature, and a second conductive resin portion 72 whose electric resistance increases in increments less than that in the electric resistance increase at the first conductive resin portion 71 when the battery temperature rises to reach the given temperature.
