Relaxor ferroelectrics are ferroelectric materials that exhibit high electrostriction. As of 2015[update], although they have been studied for over fifty years,[1] the mechanism for this effect is still not completely understood, and is the subject of continuing research.[2][3][4]
Relaxor Ferroelectric materials find application in high efficiency energy storage and conversion as they have high dielectric constants, orders-of-magnitude higher than those of conventional ferroelectric materials. Like conventional ferroelectrics, Relaxor Ferroelectrics show permanent dipole moment in domains. However, these domains are on the nano-length scale, unlike conventional ferroelectrics domains that are generally on the micro-length scale, and take less energy to align. Consequently, Relaxor Ferroelectrics have very high specific capacitance and have thus generated interest in the fields of energy storage.[9] Furthermore, due to their slim hysteresis curve with high saturated polarization and low remnant polarization, Relaxor ferroelectrics have high discharge energy density and high discharge rates. BT-BZNT Multilayer Energy Storage Ceramic Capacitors (MLESCC) were experimentally determined to have very high efficiency(>80%) and stable thermal properties over a wide temperature range.[11]
