Application of disc springs in battery energy storage

Can mechanical spring systems provide energy storage in elastic deformations?

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.

What types of springs are used in energy storage & harvesting applications?

In energy storage and harvesting applications, two key types of technical springs stand out: mechanical batteries (also known as mechanical capacitors), which use mechanical deformation to store electrical charge; piezoelectric transducers that convert mechanical stress into electrical charge through the process known as the piezoelectric effect.

Can mechanical springs be used for energy storage?

As far as mechanical energy storage is concerned, in addition to pumped hydroelectric power plants, compressed air energy storage and flywheels which are suitable for large-size and medium-size applications, the latest research has demonstrated that also mechanical springs have potential for energy storage application .

What is a mechanical energy storage system?

These springs are a mechanical energy storage system that can store potential energy through the deformation of a solid material. This stored energy can be released when needed, making it an attractive option for many applications. One common use of technical springs for energy storage is in mechanical batteries.
