In a secondary cell which generates a direct current when the positive electrode complex and the negative electrode complex thereof conduct a reversible redox reaction in the presence of an electrolyte, the positive electrode complex and the negative electrode complex are in a combination (represented by positive electrode complex/negative electrode complex) selected from the group consisting of lead/chromium complex, chromium complex/aluminium complex, and manganese complex/zinc complex. The secondary cell has relatively high capacitance and can be manufactured at low cost. Moreover, it provides more stable chemical reactions and can therefore be stably charged/discharged with large current and without risk of explosion. |
