The flywheels made of composite materials permit high density, unlike the typical steel-based flywheels with low density . Two materials are mainly used to construct flywheel energy storage systems: they are composite materials made up of carbon fiber or graphite and metal materials.
A flywheel operates on the principle of storing energy through its rotating mass. Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy.
From a cost perspective, flywheel energy storage systems made with high-strength steels are ideal for maximizing energy per dollar spent. High-strength steel flywheels offer high energy density (energy per volume) because of their high mass density. Additionally, they outperform composite materials in terms of thermal conductivity and availability.
Choosing appropriate flywheel body materials and structural shapes can improve the storage capacity and reliability of the flywheel. At present, there are two main types of flywheel materials: metal materials and composite materials. The design and processing technology of metal materials is relatively mature.
S. Kitade, K. Pullen, in Comprehensive Composite Materials II, 2018 Composite flywheels began to be actively investigated for application in energy storage in the era of the oil crises in the 1970s. This was shortly after the development of this lightweight but strong material which offers a lighter solution as compared to metallic flywheels.
The metal flywheel is easy to process and has mature technology. Although the strength of metal materials is not as strong as composite materials and cannot reach the limit rotational speed of composite flywheel, the metal density is high, and it mainly relies on large mass and large rotational inertia for energy storage.
