Structure evolution, ferroelectric properties, and energy storage performance of CaSnO3 modified BaTiO3-based Pb-free ceramics

Enhanced electrocaloric effect, energy storage density and pyroelectric response from a domain-engineered lead-free BaTi0.91Sn0.08Zr0.01O3 ferroelectric ceramic

“…Therefore, the substitution of BT can significantly increase their energy storage density. 19 Bi, Zn, and Sn doping were used by M. Zhou et al 20 to create a BT-based ceramic with an energy storage density of 2.21 J cm −3 , while Gang Liu et al 21 used Ca and Sn to produce a ceramic with an energy storage density of 1.57 J cm −3 . As a result, co-doping in one or both sites can cause the morphotropic phase boundary (MPB) to occur at room temperature (RT), resulting in improved piezoelectric, dielectric and electrocaloric characteristics.…”

Design of lead-free BCZT-based ceramics with enhanced piezoelectric energy harvesting performances

“…Accordingly, the introduction of the BTSn compound enhances the relaxor behaviour of the sample by forming polar nanoregions (PNRs). 48,49 Furthermore, the low E c value facilitates domain switching and saturation of P–E loops. 50 The small E c values might be related to the coexistence of the O–T phase, which leads to an instability of the polarization state compared to the sole presence of the T-phase.…”

Enhanced Energy Storage Characteristics in PVDF-Based Nanodielectrics With Core-Shell Structured and Optimized Shape Fillers

“…where U d and U c are the energy density during the discharging and charging processes, respectively [33], [34]. The calculated energy storage densities and efficiencies of the composite dielectrics are presented in Fig.…”
