Anti-ferroelectric ceramics in their innate state are characterized by the presence of anti-parallel dipolar alignment [37, 44, 45]. This arrangement of polar moment in the material creates a complete absence of any observable ferroelectric, piezoelectric, and pyroelectric properties.
From the literature it is evident that a compressive stress can be utilized to greatly improve the performance of AFE based capacitors [37, 43, 58, 76, 78, 89]. Thus, in order to overcome the limitation of applying pre-stresses an alternative method has been proposed, known as self-confinement, using patterned electrodes.
Discussion has been provided for the origin of anti-ferroelectricity in bulk materials and how this is best employed for energy storage applications. This was followed by discussion of various physical and chemical parameters that can be used for enhancing and tuning the energy storage density in bulk and thick film AFE materials.
