a, c Schematic entropy versus temperature curve of NPG as well as KPF6 in the absence of pressure and under applied pressure. The arrows depict pressurization. b, d Temperature-pressure phase diagrams of NPG8 as well as KPF6. For the latter, each symbol represents an experiment. Except for neutron diffraction data labeled with ND, other all are from Raman scattering. “C”, “M-I”, “M-II”, and “R” are abbreviated for cubic, monoclinic I, monoclinic II, and rhombohedral phase. The meaning of the legends are specified in the text. e Comparison of the operating temperature range of the regular BCE materials with that of KPF67,10,13,14,20,21,22,23,24,25,26,27,28 .
