Improvements in or relating to batteries

摘要

A battery (100) is basically provided with an electricity generating element (160) and a discharging section. The electricity generating element (160) has a plurality of electric cells (150) connected in series. The discharging section comprises short circuit layers (270) disposed inside the electricity generating element (160) so that electricity is constantly discharged from each of the electric cells (150) at a prescribed discharge rate, each short circuit layer (270) having a resistance such that the prescribed discharge rate is set to a value equal to or less than 0.25C and greater than the rate of natural discharge that occurs when a load is not connected to the battery (100). The battery (100) is especially useful in a power supply component of a vehicle.
