To develop a low-temperature sintering process for BTO-based relaxor ferroelectric thick films with a multi-layered structure.
Fabricated screen-printed BTO-based thick films with lead-free glass.
Employed low-temperature sintering at 900 ℃.
Utilized a sandwich structure for enhanced performance.
Achieved an energy density of 1.65 J cm−3.
Demonstrated an efficiency of 74.3% in the thick films.
Resumen
A screen‑printed BTO-based thick film with lead-free glass and sandwich structure enables low-temperature sintering (900 ℃). It achieves a high energy density of 1.65 J cm −3 , efficiency of 74.3%.
