考えられる。With respect to the electrode subjected to the heat treatment as described in the examples and the electrode of the comparative example, the leakage current and the self-discharge characteristic when a voltage was applied were measured. FIG. 2 shows a capacitor assembly diagram at the time of measurement. An electrode (25 × 25 × 1 mmt) 1 previously impregnated with a sulfuric acid electrolyte under reduced pressure was opposed to each other with a separator 2 interposed therebetween, and the current collector was pressed and held by a Teflon plate (not shown) using a platinum plate 3. This was immersed in a 5-70 wt% sulfuric acid electrolytic solution to obtain a test cell. Leakage current is equal to charging voltage 0.
8 V, charging current density is 2 mA / c with respect to the projected area of the electrode.
constant current charged at m 2, 15 from the time of charging voltage 0.8V reached
The value after time was taken. The self-discharge characteristics were determined by charging the battery in a 35 wt% sulfuric acid electrolyte under the same conditions as above, then opening the terminal and measuring the change in the terminal voltage. Fig. 3 shows the measurement result of leakage current.
FIG. 4 shows the measurement results of the self-discharge characteristics. The leakage current of the electrode 41 of the example is smaller than that of the electrode 42 of the comparative example, and it can be seen that the leakage current of the electrode of the example is reduced. In addition, the self-discharge characteristics when the sulfuric acid concentration was set to a typical 35 wt% were such that the electrode 51 of the example had a smaller terminal voltage drop than the electrode 52 of the comparative example, and the self-discharge characteristics were good. It can be seen that the leakage current has been reduced. It is considered that the reason why an electrode having such excellent characteristics can be obtained is that, since the depth of the pores is large, the area where ions are stably adsorbed near the electrode surface increases.
