However, low energy-storage density limits the evolution of capacitors toward lightweight, miniaturization, and integration. Here, an effective strategy of constructing highly dynamic polarization heterogeneous nanoregions is proposed in lead-free relaxors to realize an ultrahigh energy-storage density of ≈8.

In this study, OVs modified P/Ag/AgO/AgPO/TiO (PAgT) composite was successfully fabricated via a photoreduction process by controlling the ratio of PAgT to ethanol (16, 12, 8, 6 and 4 g·L) under simulated solar light irradiation for the first time. Characterization methods confirmed the presence of OVs in the modified catalysts.
