Three properties determine the ability of these springs to act as elastic energy stores: their stiffness, which determines the magnitude of the energy that can be stored; their resilience, which determines the fraction of the invested energy that is returned; and their resonant frequency, which determines the temporal characteristics of the .

Continued pressure in the supply chain for storage components, including battery metals, has sustained increased prices and led to production and delivery delays. For example, more than 1,100 MW of utility-scale storage capacity originally scheduled to come online in the second quarter of 2022 was delayed or canceled.

At a very low frequency, the rate of shear is very low, hence for low frequency the capacity of retaining the original strength of media is high. As the frequency increases the rate of shear also increases, which also increases the amount of energy input to the polymer chains. Therefore storage modulus increases with frequency.
