Among the many available options, electrochemical energy storage systems with high power and energy densities have offered tremendous opportunities for clean, flexible, efficient, and reliable energy storage deployment on a large scale. They thus are attracting unprecedented interest from governments, utilities, and transmission operators.
High energy storage density is required for the need of devices’ miniaturization and lightweight, since more energy can be stored when the volume is the same. An ideal energy storage dielectric should have large dielectric constant and high breakdown strength at the same time.
Storage energy density is the energy accumulated per unit volume or mass, and power density is the energy transfer rate per unit volume or mass. When generated energy is not available for a long duration, a high energy density device that can store large amounts of energy is required.
Composite materials and special structures are usually used to increase the energy storage density. At present, the maximum energy storage density of the organic–inorganic composites is above 30 J/cm 3, which is highly potential for practical applications [14, 15].
Element doping is the simplest way to increase the energy storage density of inorganic materials. It is greatly effective to increase the relaxation and reduce the remanent polarization by doping (La, Sm, Zr, etc.), which is beneficial for the energy storage density and efficiency [83, 84, 85].
The dielectric constant and energy storage density of pure organic materials are relatively low. For example, the εr of polypropylene (PP) is 2.2 and the energy storage density is 1.2 J/cm 3, while 12 and 2.4 J/cm 3 for polyvinylidene fluoride (PVDF) .
Electrochemical energy storage materials dominate the performance of various energy storage devices. For metal-ion batteries, the electronic conductivities and ionic diffusivities in the anode and cathode are the most important issues for better performance.
