Supercapacitors are fourth-generation energy storage devices that have evolved from dielectric capacitors (first generation) and electrolytic capacitors (second generation) to electric double-layer capacitors (third generation). They are gaining attention for their ability to deliver rapid energy discharge while maintaining a high energy storage capacity, effectively bridging the gap between capacitors and batteries. They use a composite of carbonaceous materials in order to greatly improve the electrochemical performance leading to high energy density. The enhanced performance comes from the combined effect of the double layer charge storage mechanism of carbonaceous materials and the pseudocapacitive nature of the transition metal oxides. The incorporation of pseudocapacitive material such as MnO2 and the electric double layer capacitor (EDLC)–type material such as carbon nanotubes (CNTs) holds great potential for the development of high-capacity, fast-charging, and reliable supercapacitors suitable for various applications. With these advancements, the hybrid MnO2–CNT supercapacitors have significant potential in electric vehicles, complementing batteries by enabling fast discharge for quick acceleration.

This talk will discuss the fabrication and performance of MnO2–CNT supercapacitors and their relationship with batteries.
