Abstract: By utilizing cylindrical helical springs which were compressed then rotated, a new energy storage method which integrated elastic potential energy and rotational kinetic energy was mentioned and the equipment model was preliminarily built. Energy-density ratios of various common spring materials were contrastively calculated to get the optimal material in energy storage ability. The rotational kinetic energy and elastic potential energy of springs at a range of parameters were contrastively analyzed. The stored energy values of integration energy storage method and corresponding flywheel method were compared.The results show that the integration energy storage method is feasible.

Key words: cylindrical helical spring, elastic potential energy, rotational kinetic energy, integration energy storage method, energy-density ratio
