When a material is subjected to a force, F, it deforms. During this deformation, the force moves over a finite displacement, x, and thus does work, F x. This work can be stored as elastic potential energy (E elastic). A perfectly elastic material returns all the work done on it and thus acts

On the basis of results recently published, the present paper constitutes an overview on the application of solid elastic systems to mechanical energy storage and aims at assessing benefits and limits of this technology for what concerns energy density, power density, energy conversion and release.
The principal functions of elastic storage device using spiral spring are energy storage and transfer in space and time. Elastic energy storage using spiral spring can realize the balance between energy supply and demand in many applications.
Energy storage in elastic deformations in the mechanical domain offers an alternative to the electrical, electrochemical, chemical, and thermal energy storage approaches studied in the recent years. The present paper aims at giving an overview of mechanical spring systems’ potential for energy storage applications.
State of the art and discussion Elastic potential energy storage in components of mechanical systems occurs when they are deformed if forces are applied to the system. A well-known elastic component is a coiled spring. The elastic behavior of springs and elastic potential energy per unit volume can be found in literature [14-15].
The working principle is shown in Fig. 2. Thus, elastic energy storage via spiral springs can improve the stability and controllability of power grid for supply and demand, improving the quality of power grid. It realizes energy transfer in time to meet the balance of energy supply and demand.
Spiral spring is the most common elastic energy storage device in practical applications. Humanity has developed various types of elastic energy storage devices, such as helical springs, disc springs, leaf springs, and spiral springs, of which the spiral spring is the most frequently-used device. Spiral springs are wound from steel strips [19, 20].
