METHOD FOR DRYING ELECTRODE PAIR, METHOD FOR MANUFACTURING LITHIUM-ION SECONDARY BATTERY, METHOD FOR MANUFACTURING ELECTRIC DOUBLE-LAYER CAPACITOR, AND METHOD FOR MANUFACTURING LITHIUM-ION CAPACITOR

摘要

This method for drying an electrode pair includes: a step in which a collector is coated with a positive-electrode material, yielding a positive electrode; a step in which a collector is coated with a negative-electrode material, yielding a negative electrode; a step in which an electrode pair (7) is produced, said electrode pair comprising one or more sets of the aforementioned positive electrode and negative electrode laminated together with a separator or separators interposed therebetween; and a step in which said electrode pair (7) is placed inside a container. Said method also includes at least one of the following drying steps: a step in which the positive electrode and/or the negative electrode is dried using a freeze-drying method; and a step in which the container containing the electrode pair is dried using a freeze-drying method. This makes it possible to provide a method for manufacturing a lithium-ion secondary battery, a method for manufacturing an electric double-layer capacitor, a method for manufacturing a lithium-ion capacitor, and a method for drying an electrode pair whereby the time it takes to dry said electrode pair can be reduced without causing defects such as wrinkles in the separator(s).
