Spiral spring energy storage harvests and stores random mechanical energy. Harvesting and storing energy is a key problem in some applications. Elastic energy storage technology has the advantages of wide-sources, simple structural principle, renewability, high effectiveness and environmental-friendliness.
Based on 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, such as energy adjustment of power grid. Continuous input–spontaneous output working style.
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].
Lifting machinery. An elastic energy storage device using a spiral spring has been designed for lifting machinery. The gravitational potential energy of the load weight can be converted into elastic potential energy within the spiral spring during the descending process.
This work proposes a spiral-based mechanical energy storage scheme utilizing the newly synthesized 2D diamane. Atomistic simulations show that diamane spiral can achieve a high theoretical gravimetric energy density of about 564 Wh kg −1, about 14 500 times the steel spring.
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.
