What are the advantages and disadvantages of elastic energy storage technology?

Harvesting and storing energy is key problem in some applications. Elastic energy storage technology, especially the using of energy storage with spiral spring has many advantages in practical applications. The advantages include simple structure, high reliability, high storage density of energy, convenience to use, and technological maturity.

What is the most common elastic energy storage device?

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].

What is elastic energy storage?

Compared with the traditional chemical battery, elastic energy storage does not automatically release energy due to self-discharge, therefore the energy can be stored for a much longer time and can be repeatedly stored and released.

What are the functions of elastic storage device using spiral spring?

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.

What is elastic energy storage – electric power generation system?

With the elastic energy storage–electric power generation system, grid electrical energy can drive electric motors to wind up a spiral spring group to store energy when power grid is adequate, and the stored energy can drive electric generators to generate electrical energy when power grid is insufficient. The working principle is shown in Fig. 2.

Can elastic energy storage technology be combined with other energy conversion approaches?

Elastic energy storage technology could also be combined with other energy conversion approaches based on the electromagnetic, piezoelectric principle which can present unique advantages and realize the multidisciplinary integration , , .
