Electroceramics for High Performance Supercapicitors

The book describes the state-of-the-art analyses of high-density supercapacitors.

In the near future, high-energy density materials will be required to accommodate the increased demand for gadgets, hybrid cars, and massive electrical energy storage systems. Fuel cells, supercapacitors, and batteries have the highest energy densities, but traditional capacitors have gained attention for intermittent energy harvesting owing to their high energy transfer rate and quick charging/discharging capability. The large amount of electric breakdown strength and modest remnant polarization are keys to the high energy density in dielectric capacitors. Above 100??C or 212??F, polymer dielectric capacitors become unstable and begin to suffer a dielectric breakdown. Hence, dielectric ceramics are the sole viable option for high-temperature applications.

This book provides a basic understanding of dielectric-based energy harvesting. After a detailed analysis of the state-of-the-art, it proceeds to explain the specific strategies to enhance energy storage features, including managing the local structure and phases assembly, raising the dielectric width, and enhancing microstructure and electrical uniformity. Also discussed is the need for novel materials with applications in high-density supercapacitors.
