Why is there no spring based energy storage?
Jan 11, 2021 at 14:44. 1. In some sense, lithium-ion batteries and lithium-polymer batteries can be thought of as "spring-based" storage systems. They rely on intercalation of the lithium ions between the layers of some other substrate, which has the effect of pushing the substrate layers apart when the battery is charged.

China Coil Spring Energy Storage: A Sustainable Solution for Efficient Energy Storage
Coil spring energy storage is a method of storing mechanical energy using coiled springs. It works by converting electrical energy into potential energy, which is stored in the stretched springs. When the energy is needed, the springs release their stored energy, which can be converted back into electrical energy or used to power mechanical devices.
