Obtaining high energy storage performance and thermal stability simultaneously in BiFeO3–BaTiO3–Bi2LaTiNbO9 lead-free relaxor ferroelectric ceramics

Achieving outstanding temperature and frequency stability in NaNbO3-modified (Ba0.94Li0.02La0.04)(Mg0.04Ti0.96)O3 pulse energy storage ceramics

“…Therefore, the t 0.9 value decreases on increasing the electric eld. 3,11,13,29,32,34,[36][37][38][39][40][41][42][43][44] The W d value is slightly less than the W rec value due to the different test systems. 1,2 On the other hand, the rapid switching of the dipole moment during the pulse test system than that of the ferroelectric test system results in an inevitable loss of the energy, causing a W d less than W rec .…”
