A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large flywheel rotating on mechanical bearings. Newer systems use composite

Most of the BESS systems are composed of securely sealed , which are electronically monitored and replaced once their performance falls below a given threshold. Batteries suffer from cycle ageing, or deterioration caused by charge–discharge cycles. This deterioration is generally higher at and higher . This aging causes a loss of performance (capacity or voltage decrease), overheating, and may eventually l.

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable which employs ions as . The battery uses vanadium's ability to exist in a solution in four different to make a battery with a single electroactive element instead of two.
