限されることになる。As a battery system, ■ polyacetylene is used for the positive and negative electrodes, and ion doping is a charging reaction, and undoping is a discharging reaction; ■ polyacetylene is used for the positive electrode, and Li is used for the negative electrode.
Doping and precipitation of alkali metals are carried out using alkali metals such as photoelectric reactions. For example, in the case of ■ battery, L I
A solution of Clch in a mixed solvent of propylene carbonate and dimethoxyethane is used. Although the liquid 4 electrolyte has a high conductivity and can provide good battery performance, there is a problem with the reliability of the battery due to leakage due to the sealing properties. In order to solve these problems, secondary batteries that use a solid electrolyte as one solution are being considered [Polymer

The negative electrode consists of a negative electrode made of polyacetylene and a solid electrolyte made of a mixture of polyethylene oxide and NaI. Although this battery does not have the above-mentioned concern about liquid leakage, a new problem arises in that the charging pH and discharging current density cannot be maintained high, and as a result, the application range of this battery is limited to 1UIJ.

る。As shown in Fig. 41, in a conventional solid electrolyte secondary battery, the polyacetylene J electrode and the solid electrolyte are each independent, and they are brought into close contact with each other when the battery is constructed. Therefore, when looking at the contact surface between the electrode and the solid electrolyte, the solid electrolyte is in contact only with the surface of the polyacetylene membrane, and the transfer of doped ions from the solid electrolyte to the polyacetylene takes place in a very narrow area. In other words, there are fewer active sites for electrode reactions, and current density cannot be maintained.

とれるという結論に至った。The present inventors focused on the fact that the bulk density of the polyacetylene film used as the electrode active material ranges from 0.15 to 0.9, and the specific surface area ranges from 50 to xoom"/g. That is,
For these reasons, there are micropores in the polyacetylene model.
It is necessary to have a solid electrolyte in this part as well.
They concluded that this increases the number of active sites for the stain electrode reaction and allows for higher current densities.
