| Research Abstract |
We have developed a novel photo-rechargeable battery using quasi-one-dimensional compound KFeS2. As results, i) the photo-charged quantity, Qph,was increased in proportion to irradiation time, ii) the electromotive force was increased with the photo-irradiation time, but maintained almost the constant value under irradiation stop. From the results, it was confirmed that the cell was charged by photo-induced copper intercalation into KFeS2.To improve the Qphof photo-rechargeable battery, we evaluated four electrolytes.As a result, a pressed electrode using potassium-iodide methanol solution showed higher Qphthan the others.
