“…1 is non-trivial. Defects with a wide range of concentrations can be prepared experimentally, including FP concentrations of 0.2–0.6 at.% in most metals at low temperature 31 and up to 3 at.% in graphite at room temperature 27 . Our choice of 1 at.% represents a practically achievable limit in most materials.…”

Energy 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. We first estimate upper limits and trends for energy storage using defects. First-principles calculations are then employed to compute the stored energy in the most promising elemental materials, including tungsten, silicon, graphite, diamond and graphene, for point defects such as vacancies, interstitials and Frenkel pairs. We find that defect concentrations achievable experimentally (~0.1–1 at.%) can store large energies per volume and weight, up to ~5 MJ/L and 1.5 MJ/kg for covalent materials. Engineering challenges and proof-of-concept devices for storing and releasing energy with defects are discussed. Our work demonstrates the potential of storing energy using defects in materials.

“…Saturation resistivities for neutronirradiated Zr have been reported previously from four experiments: kosenbaum et al 1 give ap s » 24 nn.m for Zr irradiated at 77 K, Vialaret et al 2 report ap s * 100 nn.iu for irradiation at 24 K, while Nakagawa et al 3 and Klabunde and Coltman give values of zoo n .ai and 47 nfl.m, respectively, for irradiation at 4.5 K. It has been suggested that the large range of £p s measured (and thus of V r calculated) may originate from differences in irradiation temperature. Other possible sources for the discrepancy could be trace impurities, spectrum effects, or simply the difficulty in extrapolating the damage-rate curves.…”
