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][5] Examples of relaxor ferroelectrics include: 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.
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.
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.
