<p>The present invention provides a manufacturing method for a secondary battery electrode, the method enabling the temperature of hot air to be appropriately maintained whilst the air volume is reduced to a lower volume compared to prior art in order to reduce the cost of the secondary battery. Also provided is a hot air drying furnace used in the manufacturing method. The temperature (TA) of the hot air at the blowing position (point A) of a nozzle (4) is measured by a temperature sensor (7), the temperature (TB) of the hot air at a point B, which is downstream of the point A in the direction that the hot air flows, is measured by a temperature sensor (8), and the temperature (TC) of the hot air at a point C, which is downstream of the point B, is measured by a temperature sensor (9). A control device (5) uses the temperature (TB) and the temperature (TC) to calculate an amount (dT) by which the temperature of the hot air at the point A has decreased as a result of the latent heat of vaporization of an electrode paste. The control device (5) also adds the amount (dT) to a set temperature (TS) for the hot air at the point A so as to calculate a corrected set temperature (TSn) for the hot air, and adjusts the output to a heater (10) according to the difference (dTA) between the corrected set temperature (TSn) and the temperature (TA) measured by the temperature sensor (7).</p> |
