Schematic illustration of ferroelectrics enhanced electrochemical energy storage systems. 2. Fundamentals of ferroelectric materials. From the viewpoint of crystallography, a ferroelectric should adopt one of the following ten polar point groups—C 1, C s, C 2, C 2v, C 3, C 3v, C 4, C 4v, C 6 and C 6v, out of the 32 point groups.

Ferroelectric materials are substances with spontaneous electrical polarization. Polarization refers to the separation of the negative and positive charges within a material. For ferroelectric materials, this means the "memory" of the material''s prior state (referred to as hysteresis) can store information in a way similar to magnetic
