Customer ServiceEnergy storage occurs in a variety of physical and chemical processes. In particular, defects in materials can be regarded as energy storage units since they are long-lived and require energy to be formed. Here, we investigate energy storage in non-equilibrium populations of materials defects, such as those generated by bombardment or irradiation.
Even a small and readily achievable defect concentration of 0.1 at.% can store energy densities of up to ~0.5 MJ/L and ~0.15 MJ/kg. Practical aspects, devices, and engineering challenges for storing and releasing energy using defects are discussed. The main challenges for defect energy storage appear to be practical rather than conceptual.
Generally speaking, according to the nature of crystal defect engineering, the main roles of defects in energy storage and conversion systems can be summarized as follows ( Fig. 12 ): (I) Crystal defects can be exploited as energy storage/adsorption/active/nucleation sites.
To alleviate volume variation resulting from changes in internal strain and stress, doping engineering and topochemical substitution can regulate crystal structures to reduce how much the volume changes. To date, many studies have been conducted to understand the relationship between defect engineering and energy storage.
