3.2eVの材料に限られるのが現状である。Conventional technology Attempts to develop secondary batteries that can be charged with light include, for example, Masao Kaneko, Electronics, P97-104 (S59, 10).
As shown in the review paper, many studies have been done,
The one currently in use uses solar cells to charge ordinary secondary batteries. In addition to the two-stage type, which stores power generated by solar cells in a secondary battery, electrodes made of a semiconductor such as n-type TiO2 ,
The semiconductor electrode is immersed in an electrolyte with an electrode made of a metal such as platinum or a semiconductor such as p-type GaP, and the semiconductor electrode is irradiated with light to cause charge separation (creating holes in the valence band and electrons in the conduction band). ), attempts have been made to oxidize and reduce substances in the electrolyte with photo-induced charges, store them as active materials, and use them during discharge, but this has not yet reached the level of practical use. In order for the photo-excited charges to carry out the subsequent oxidation and reduction reactions, the oxidation and reduction potentials of the substances in the electrolyte must be above the top of the valence band of the semiconductor electrode, and the reduction potential must be below the bottom of the conduction band. In particular, in order to perform as much charge separation as possible by photoexcitation, it is necessary that the band gap of the semiconductor electrode be small, but if the band gap is too small, the condition cannot be satisfied, and the subsequent electrochemical reaction will not proceed. Therefore, the bandgap of a semiconductor that satisfies the conditions of and is desirable for absorbing sunlight or fluorescent light and efficiently proceeding with the reaction is 1 to 1.
Semiconductors with such a band gap (n-type Si ~ 1.1 eV, n-type GaAs ~
1.35eV, CdS to 2.4eV) have the problem that they themselves participate in the reaction and corrode.
Stable materials in aqueous electrolytes include TiO 2 and ZnO, which can only be used with ultraviolet light, and have a band gap of 3.0 or more.
Currently, it is limited to materials with a voltage of 3.2eV.

~166´82) summarizes the research of his own and others and discusses the possibility of batteries that can be charged with light. Considering the use of sunlight, batteries with Li as the negative electrode require too much energy to charge efficiently, making it impossible to charge them efficiently. From the viewpoint of efficiency, it is predicted that it would be better to replace the negative electrode with something like Cu, which has a noble oxidation and reduction potential. This can be easily considered from the above conditions. In addition, it is necessary for the electrode to maintain semiconductivity during the photocharging process, and B.G. , Jacob et al.

的としたものである。Problems to be Solved by the Invention The inventors have previously provided a secondary battery that uses n-type ZrS 2 and HfS 2 and can be charged with light. However, batteries using the above-mentioned materials as positive electrodes have the drawback of large polarization during discharge. The present invention aims to solve such problems.

活性化エネルギーが低下し、結果的に分極が小さ
くなつた。Function A major cause of battery polarization is the activation energy of charge transfer at the interface between the electrolyte and the positive electrode material. This means that it has passed through the electrolyte.
Cu + receives electrons from the positive electrode material, becomes Cu, and is stored in the positive electrode material. This flow of electrons is the function of the battery, but it is consumed during the exchange of electrons between Cu + and the positive electrode material. The energy that occurs is called the activation energy of charge transfer. Of course, the lower the activation energy, the more sensitive the transfer of electrons, and the smaller the polarization of the battery. Doping Zr sulfide with Mo lowered the activation energy mentioned above, resulting in smaller polarization.

る事がわかる。 FIG. 2 shows the change in battery voltage over time when discharging and photocharging were repeated in the above battery. Discharge is 1MΩ constant resistance load discharge.
After a certain period of time, light irradiation was performed at the same time as the discharge was stopped. In the figure, the ○ mark indicates an example of the present invention, and the □ mark indicates a comparative example in which ZrS 2 is the main material of the positive electrode.

It was irradiated with The discharge characteristics of this battery are shown in FIG. The discharge current was 200 μA, and the ○ and □ marks are the same as those in FIG. 2. Looking at this, it can be seen that the discharge characteristics of the product of this example are significantly improved compared to the comparative example.

冷却したものにRbCu4I1．5Cl3．5を混合した。Example 2 As a positive electrode, 60 mg of a mixture of MoS 2 powder, ZrS 2 powder, and RbCu 4 I 1.5 Cl 3.5 powder in a weight ratio of 1:1:3 was used, and the rest was the same as in Example 1 above. The same 1MΩ battery as above was prepared under the same conditions.
FIG. 4 shows the change in battery voltage over time when constant resistance load discharge and photocharging were repeated. In this case as well, as in Example 1, a remarkable improvement in discharge characteristics is observed. However, the positive electrode is first made of MoS 2
and ZrS 2 were mixed, pressed under a pressure of about 3 tons, held at 800°C for 72 hours, cooled to room temperature, and mixed with RbCu 4 I 1.5 Cl 3.5 .
なお、上記正極材料のMoS2及びZrS2は不定比
化合物であり、これがMoSY、ZrSy（1.8≦Ｙ≦
2.1）であつても、同様の結果を得る事は言うま
でもない。 In addition, MoS 2 and ZrS 2 of the above-mentioned positive electrode materials are non-stoichiometric compounds, which are MoS Y and ZrS y (1.8≦Y≦
2.1), it goes without saying that similar results can be obtained.

Cu+のみであり、正極材料の腐食はおこらない点
にある。 In addition, the reason for using a solid electrolyte is that when the electrolyte is a liquid, when light is irradiated on the bonding surface with the positive electrode,
Both cations and anions participate in the reaction, which causes corrosion of the positive electrode material, but in the case of the solid electrolyte used in the photosecondary battery in this example, it is only the cations and anions that react.
Since it is only Cu + , corrosion of the positive electrode material does not occur.
