An objective of the present invention is to provide a secondary battery and a battery module, each of which is suppressed in unintended battery deterioration by adequately controlling the electric current flowing through a diode portion. Another objective of the present invention is to provide a nonaqueous secondary battery and a battery module, in each of which the positive electrode and/or the negative electrode is held in a desirably charged state by the above-described electric current control. A nonaqueous secondary battery of the present invention comprises a positive electrode (200), a negative electrode (300) and an electrolyte solution, and is charged and discharged by repeating a reaction wherein ions are desorbed from the positive electrode (200) or the negative electrode (300) into the electrolyte solution or absorbed from the electrolyte solution. This nonaqueous secondary battery is characterized by being provided with an ion supply source (401) which dissolves ions of the same kind as the above-described ions into the electrolyte solution, and a first mesh electrode (400) which is in contact with a part of the surface of the negative electrode (300). This nonaqueous secondary battery is also characterized in that a first diode (402) and a first resistor (403) are provided between the ion supply source (401) and the first mesh electrode (400). |
