Abstract: A control system for a secondary battery that effectively performs temperature control of the secondary battery before getting to a charging station, thereby enabling high speed charging, is provided. It relates to a vehicle including a first secondary battery, a second secondary battery, a first temperature control unit, a secondary battery monitoring unit, and an arithmetic unit. The secondary battery monitoring unit acquires remaining amount data of the first secondary battery. The arithmetic unit compares the remaining amount data and a set value. In the case where the remaining amount data is smaller than the set value, the secondary battery monitoring unit acquires the temperature of the first secondary battery. The arithmetic unit calculates an adjustment term required to adjust the temperature of the first secondary battery to a set temperature. The arithmetic unit calculates an arrival term required to get to a set charging station. The first temperature control unit starts adjusting the temperature of the first secondary battery to the set temperature, with electric power fed from the second secondary battery, in the case where the adjustment term is shorter than or equal to the arrival term.

Abstract: A positive electrode for a secondary battery having excellent cycle performance is provided. The positive electrode for a secondary battery includes a positive electrode current collector layer, a base film, a positive electrode active material layer, and a cap layer; the base film contains titanium nitride; the positive electrode active material layer contains lithium cobalt oxide; and the cap layer contains titanium oxide. The use of titanium nitride for the base film can inhibit oxidation of the positive electrode current collector and diffusion of metal atoms while ensuring an adequate conductivity. The use of titanium oxide for the cap layer can inhibit a side reaction between the positive electrode active material layer and an electrolyte and collapse of a crystal structure of the electrode active material, improving the cycle performance.
