abstract = {The ability to work at ultralow (−90 °C) or ultrahigh
(200 °C) temperature with superior energy storage
properties is essential for dielectric capacitors to operate
in harsh environments. Here, we realized an ultrahigh
recoverable energy density (Wrec) (78.7 J cm−3) and
efficiency (η) $(80.5\%)$ in BaZr0.35Ti0.65O3 film
capacitors through enhancing the breakdown electric field
strength at room temperature. Moreover, the BaZr0.35Ti0.65O3
film capacitor exhibits great energy storage properties when
measured from −150 °C to 200 °C. Wrec and η can reach
the value of 41.9 J cm−3 and $66.4\%$ under an electric
strength of 4.0 MV cm−1 even at 200 °C, respectively.
Especially, the variation of both Wrec and η at 200 °C
during 1 × 106 cycles (ferroelectric fatigue tests) is less
than $3\%.$ All these reveal that the BZT film capacitor is
a commendable material for application in equipment working
in harsh environments.},
