摘要： A high energy density flywheel has a central rotating axle for storing kinetic energy. The flywheel comprises a first member to be operatively mounted around the axle. The first member comprises a first material having a given high mass density enabling a given high kinetic energy storage capacity. The flywheel comprises a second member operatively attached to the first member. The second member surrounds an outside portion of the first member subject to radial forces generated by a rotation of the flywheel. The second member comprises a second material having a given high yield strength enabling a given high maximum rotational speed. The second member enables an operation of the flywheel at a given high flywheel rotational speed greater than the rotational speed that would be allowed by the maximal yield strength of the first material, to thereby provide the flywheel with a given high kinetic energy storage capacity.
