Overview
Calcium copper titanate (CCTO) is a perovskite-related ceramic material renowned for its exceptionally high dielectric permittivity, which makes it one of the most promising materials for energy storage applications. Its unique grain-boundary response mechanism allows it to achieve colossal dielectric constants, making it ideal for next-generation capacitors and supercapacitors. The higher the dielectric permittivity, the more energy the capacitor can store.

Key Properties

• Extremely high dielectric constant – outstanding energy storage density.

• Good thermal stability – maintains performance at elevated temperatures.

• Stable crystal structure – reliable performance over extended use.

• Suitable for integration into electronic devices and systems.

Applications

• Capacitors and supercapacitors: High-capacitance devices for energy storage.
