How a Flywheel Battery Stores and Delivers Energy
Because energy storage relies on a physical process rather than a chemical reaction, flywheels can endure over 100,000 charge and discharge cycles, lasting for decades

And because they avoid chemical reactions, they do not suffer from typical battery issues like capacity loss or thermal runaway. Many flywheel systems are rated for more than
In electromechanical systems, the kinetic energy of a moving mass stores electrical energy. The most prevalent type of mass in an
Unlike traditional batteries that use chemical reactions for energy storage and release, flywheels turn kinetic energy into power. Picture a spinning top;
The extended lifespan of FESS, with minimal degradation over time, stems from the absence of chemical reactions, reducing wear and tear, and ensuring consistent
When a flywheel is used entirely for its effects on the attitude of a vehicle, rather than for energy storage, it is called a reaction wheel or a control moment gyroscope.

Compared 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 specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 13
Unlike chemical batteries, flywheels do not rely on chemical reactions to store and release energy, reducing energy loss. This mechanical storage method ensures a high round
