Discharge until the voltage reaches 5V, and calculate from the amount of electricity obtained during this time. In the case of the plastic battery produced under the conditions (B) above, the energy density was 154.4QAh/on average.
kg, and the current during charging was stable. On the other hand, a plasti/electrode made using a conventional electrode (see Figure 3), which uses an ordinary nickel plate not coated with polymer as the positive electrode terminal, and combines a positive electrode and a negative electrode in a layered manner.
In addition to having a low energy density of 104.6 Ah/kg, batteries often have a large and unstable current flowing during charging, in which case they cannot be charged or discharged and do not function as a battery. Next, an example of a plastic battery electrode according to claim 2 and a manufacturing method thereof according to claim 4, which is a polymer composite membrane A1 obtained in the explanation (B) of the above example.
In No. 2, the nickel foil was not removed from the polymer composite film AI2, and was used as a metal foil current collector CA13 coated with the polymer composite film, and the Niacel terminal B was closely attached to the end of the nickel foil. Similar to the above example, the effect of the plastic battery constructed using the electrodes of this example is that the current during charging is stable compared to the conventional plastic battery manufactured using the 1-electrode (see Figure 4). .
