From: Using defects to store energy in materials – a computational study
The energy density and specific energy stored in materials defects, shown here for a 1 at.% concentration of FPs in bulk materials and SW defects in graphene. The inset zooms into the gray shaded region. The FP (or SW) formation energies computed here (red circles) are taken from Table S1 and those obtained from the literature (blue squares) are given in Table S3 (see Supplementary Information). The experimental27,28,29 (green triangle) and computed stored energy for a 3 at.% concentration of FPs in irradiated graphite are also shown. For comparison, we plot the range of stored energies in Li-ion and Ni-MH batteries20.
