a Schematic illustration of the internal structure of the full cells. b Typical voltage profiles of HPJH-AlSi/Na | | NVP cells at the specific current of 117.6 mA g−1. c Long-term cyclic stability of the different full cells and the corresponding Coulombic efficiency (Right panel). d In situ EIS results of the HPA-AlSi/Na | | NVP. e Corresponding contour plots of the calculated DRT results from HPJH-AlSi/Na | | NVP. f Rate capability of the different full cells and the corresponding Coulombic efficiency (Right panel). All full cells were tested under the cut-off voltage window of 2.5–3.8 V and NVP loadings of 5 mg cm−2. All the tests were measured at 25 °C. Source data for (b–f) are provided as a Source Data file.
