Outline of Final Research Achievements |
Rocking-chair-type photorechargeable battery was studied. Prior to this research, a n-type photorechargeable electrode, which can store electrochemical energy by anion dedoping under UV irradiation, was developed using porous TiO2-Polyaniline (TP) composite. In this research, a p-type photorechargeable electrode that can store energy by anion doping was investigated using a composite of a porous copper oxide and a polypyrrole (PPy). As a result, we successfully obtained homogeneous nano-porous CuO films. Composite films of the porous CuO and a PPy polymerized by electrochemical deposition showed p-type photorechargeablity, however, the photochareged quantity was lower than the target value of 20 mC/cm2. This is caused by inhomogeneous deposition of PPy on the surface of porous CuO. Through this research, the cell configuration for photorechargeable battery with high performance was suggested.
