Fig. 5: Temperature stability of energy storage performance of BSCNT0.30 ceramics.

a P-E loops with different temperatures at 500 kV cm−1. b Variation of recoverable energy density and efficiency with temperature. c XRD patterns of BSCNT0.30 ceramics at different temperature. d Raman spectra of BSCNT0.30 ceramics at different temperature. e Comparison of this work with other recently published TTBs ceramics for variable temperature energy storage performance.
