INDUSTRIAL APPLICATION FIELD The present invention relates to a secondary battery using a polymer substance as an electrode material. Conventional configurations and their problems Recently, it has been known that doping polymers with certain substances improves their electrical conductivity, and that some polymers even exhibit metallic conductivity. It is called a synthetic metal. Representative examples include polyacetylene and polyphenylene. These are because the π electrons of carbon atoms in the polymer main chain are delocalized between the main chains due to conjugated double bonds.
By doping it with a certain type of substance, it exhibits high electrical conductivity. A new type of secondary battery using this type of polymer material as an electrode material is described in, for example, Japanese Patent Laid-Open No. 136469/1983. The charge/discharge reaction when a polymeric material is used as the positive electrode is a charging reaction due to the uptake of anions in the electrolyte of the polymeric material (doping), and a discharging reaction due to the release of anions (undoping). When used, a charging reaction occurs due to the uptake of cations, and a discharging reaction occurs due to the release of cations. Charging and discharging reactions using polyacetylene (CH) o as the polymer material and a solution of lithium perchlorate dissolved in, for example, propylene carbonate as the electrolyte are shown below. Positive electrode (CH) o +nx (ClO 4 - ) Charge-→ ←- Discharge [CH (ClO 4 ) x ] o +nxe (1) Negative electrode (CH) o +nxe+nxLi + Charge-→ ←- Discharge [(CH)Li x ] ( 2) Since the polymeric substance functions as a positive electrode or a negative electrode in this way, a secondary battery can be constructed not only by combining it with other negative electrodes or positive electrodes but also by combining polymeric substances with each other. In addition to the above, known polymeric substances of this type include polyphenylene sulfide, polypyrrole, and polyacetylene in which some of the hydrogen atoms are substituted with halogen atoms, alkyl groups, phenyl groups, alkylphenyl groups, halophenyl groups, etc. It is being On the other hand, when a polymer material is used as a negative electrode, the electrolyte used in combination with it is lithium such as lithium perchloride (LiClO 4 ), lithium borofluoride (LiBF 4 ), or lithium hexafluorophosphate (LiPF 6 ). Organic electrolytes are known that use salt as a solute and propylene carbonate or tetrahydrofuran as a solvent. However, when the above-mentioned polymeric substances were used for electrodes, there was a drawback that high rate charging and discharging was difficult. OBJECT OF THE INVENTION An object of the present invention is to provide a polymer material electrode that is capable of high rate charging and discharging. Structure of the Invention The present invention uses polynitrile as a positive electrode or a negative electrode, and uses an electrolytic solution containing a solute containing anions and cations that are incorporated into or released from the polynitrile during charging and discharging. It is a feature. The structure of polynitrile is shown below. (-CH=N)- (3) Description of Examples Examples as positive electrodes of secondary batteries are shown below. Example 1 Propylene carbonate in which 1 mol/l of lithium perchlorate was dissolved in an electrolytic solution was used. As a counter electrode or negative electrode, size 2 cm x 2 cm, thickness 1 mm
A lithium plate was used as the reference electrode. As a comparative example, polyacetylene and polynitrile were used as positive electrode materials. The polyacetylene used was a film having a size of 2 cm x 2 cm and a weight of 50 mg, and the polynitrile used was obtained by compressing 50 mg of powder into a sheet shape of 2 cm x 2 cm. As shown in FIG. 1, these positive electrode materials 1 were adhered to a titanium plate 3 as a current collector using carbon dye 2 to form an electrode. All charge/discharge tests were conducted at 20°C. Charge until the potential of the positive electrode reaches +4.2V with respect to the reference electrode.
Further, the discharge continued until the voltage reached +2.0V. After the first cycle of charging and discharging was performed at 0.12 mA, all subsequent charging and discharging cycles were performed continuously at 4 mA. FIG. 2 shows the charging curve and discharging curve of each positive electrode in the 10th cycle. In the figure, A is polyacetylene and B is polynitrile. Also the first
The table shows the charging capacity and discharging capacity in the 10th cycle. It can be seen that polynitrile is superior.

A zinc plate was used as the counter electrode, that is, the negative electrode, and a saturated acetate electrode was used as the reference electrode. Charging and discharging were performed until the positive electrode reached +0.16V with respect to the saturated electrode, and discharge was performed until the voltage reached -0.24V. The first cycle of charging and discharging was performed at 0.12 mA, and the second and subsequent cycles were all performed at 4 mA. Table 2 shows the charge capacity and discharge capacity of each positive electrode in the 10th cycle. Even when an aqueous solution is used as an electrolyte, the polynitrile of the present invention exhibits excellent properties.

It can be seen that it shows superior performance compared to conventional polyacetylene. Examples as a secondary battery negative electrode will be described below. Example 3 An electrode as shown in FIG. 1 was constructed as a negative electrode in the same manner as shown in Example 1. However, in the electrode configuration shown in FIG. 1, the carbon paint in 2 was platinum paint, and the current collector in 3 was a nickel plate instead of a titanium plate.

All charging and discharging were performed until the potential of the negative electrode reached +0.2V with respect to the lithium reference electrode, and discharged until the potential of the negative electrode reached +2.0V. The charging/discharging current in the first cycle was 0.12 mA, and charging/discharging was performed at 4 mA in the second and subsequent cycles. Figure 3 shows

せることができる。[Table] In this example, titanium disulfide was used as the counter electrode, that is, the positive electrode, and the characteristics of the negative electrode were evaluated using the change in potential with respect to the lithium reference electrode as a parameter. This is because this method allows the characteristics of the negative electrode to be clearly understood. Even when the same electrode as in Example 1, that is, a polymer material was used for the positive electrode, the characteristics of the negative electrode were the same. Furthermore, when the charge and discharge characteristics of a polymeric material as a negative electrode were examined using an aqueous solution containing dissolved zinc iodide as an electrolyte, the polynitrile of the present invention was superior to polyacetylene. From the above, even when polynitrile is used as a negative electrode, it is possible to take in and release cations such as lithium ions and zinc ions from organic electrolytes or aqueous solutions as a charge/discharge reaction, compared to conventional polyacetylene. , showed excellent performance. It has been shown that when polynitrile is used for the positive electrode or negative electrode, its charge-discharge characteristics are improved. From this, it is clear that the charge/discharge characteristics of the secondary battery are improved by using it for either or both of the positive electrode and the negative electrode of the secondary battery. Effects of the Invention According to the present invention, it is possible to improve the charging and discharging characteristics of a secondary battery using a polymeric substance as a positive electrode and/or a negative electrode.
