Batteries and Other Energy Storage Devices

The range and diversity of batteries used as a source of electrical power is truly enormous, reflecting the immense range of uses of electrical power. They range in size from tiny button cells storing milliwatthours of energy and delivering microwatts of power to giant load levelling batteries, the size of buildings, storing megawatthours and delivering megawatts. The diverse range of applications has spawned a multitude of specialist batteries, each optimised for a particular use. Some of the applications for which unique batteries have been designed are outlined below.
