摘要：

In　this　work,　an　outstanding　recoverable　energy　density　(2.88　J/cm(3))　was　achieved　under　a　low　field　of　150　kV/　cm　by　introducing　4.0　mol.%　NaTaO3(NT)　into　0.76　K0.5Bi0.5TiO3-0.24BiFeO(3)　(abbreviating　as　4NT),　which　is　fabricated　by　the　conventional　solid　oxide　reaction　route.　Introduction　of　NT　enhances　the　relaxor　behavior,　and　favors　the　temperature　insensitivity　of　energy　storage　performance.　Furthermore,　the　polarization　contribution　coming　from　the　remanent　ferroelectric　order　makes　the　4NT　sample　show　excellent　recoverable　energy　density.　Our　findings　provide　the　promising　perspective　of　K0.5Bi0.5TiO3-based　ceramics　in　dielectric　energy　storage　application.
