The anatomy of a flywheel energy storage device. Image used courtesy of Sino Voltaics . A major benefit of a flywheel as opposed to a conventional battery is that their expected service life is not dependent on the number of charging cycles or age. The more one charges and discharges the device in a standard battery, the more it degrades.
