Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy. .
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. .
TransportationAutomotiveIn the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that. .

GeneralCompared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high .
Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical . They are also less potentially damaging to the environment, being. .

[pdf] Typically, in LIBs, anodes are graphite-based materials because of the low cost and wide availability of carbon. Moreover, graphite is common in commercial LIBs because of its stability to accommodate the lithium insertion. The low thermal expansion of LIBs contributes to their stability to maintain their discharge/charge. .
The name of current commercial LIBs originated from the lithium-ion donator in the cathode, which is the major determinant of battery performance. Generally, cathodes consist of a complex lithiated compound. .
The electrolytes in LIBs are mainly divided into two categories, namely liquid electrolytes and semisolid/solid-state electrolytes. Usually, liquid electrolytes consist of lithium salts. .
As aforementioned, in the electrical energy transformation process, grid-level energy storage systems convert electricity from a grid-scale power network into a storable form and convert it back.
