5 FAQs about [Bmt energy storage]
Why is BMT chosen as a base system for flexible energy storage thin film?
In view of its high spontaneous polarization and low leakage current, BMT is chosen as the base system for the flexible energy storage thin film in our previous work .
What is the energy storage density of bmt-0.3sto film capacitor?
A superior energy storage density of 109.7 J cm −3 and a pretty high efficiency of 80.6% are simultaneously achieved in the BMT-0.3STO film capacitor.

Is BMT A dopant?
BMT is widely employed as a dopant in many ferroelectric/dielectric materials for piezoelectric and energy storage applications, while ferroelectric thin films with BMT as a main constituent are rarely reported in the previous studies , , .
What is the ultrafast discharge rate of bmt-0.3sto film capacitor?
Finally, ultrafast discharge rate of τ 0.9 = 1.68 μs is obtained, which is comparable to the recent flexible film capacitors , , . The BMT-0.3STO film capacitor can exhibit excellent Wrec and η simultaneously, which is not common in other dielectric material systems.
How does BMT affect phase transition temperature?
With the increase of BMT, the phase transition temperature Tm of ceramics moves to low temperature. This is because the introduction of small-size ions Ti 4+ in BMT substitutes the Nb 5+ ions with a larger radius at the B site in KNN ceramics [37, 38, 39], which distorts the crystal lattice and leads to the decrease of Tm.
