In this research, we aim to realize a maintenance-free on-board device by solidifying the electrolyte in the photorechargeable battery, which is a combination of a solar cell and a storage battery into one device. However, solid electrolytes have problems such as poor connection with electrodes and low ionic conductivity. Therefore, the electrodes were made into nanofibers and their effects were investigated. When LiMn₂O₄ was made into nanofibers, an increase in the diffusion coefficient of Li ions was confirmed by preliminary measurements using a liquid electrolyte.
