Functions of portable electronic equipments, such as portable telephones, lap-top computers and digital cameras, have diversified and the power consumption of such portable electronic equipments has increased considerably due to their diversified functions. The batteries presently used in portable electronic equipments are lithium-ion secondary batteries. They do not always satisfy the userpsilas needs, because the time per charge is relatively short and the charging time is relatively long. Since it is expected that the energy density required by portable electronic equipments will become several times that presently required, there are demands to realize a power supply that may replace lithium-ion secondary battery.
