Mechanical Energy: Storage of Mechanical Energy Based on Carbon Nanotubes with High Energy Density and Power Density (Adv. Mater. 9/2019)

Abstract

Ultralong carbon nanotubes (CNTs) exhibit extraordinary mechanical tensile strength of over 100 GPa, and a Young's modulus over 1 TPa. CNTs are considered to be one of the strongest materials ever found and exhibit overwhelming advantages for storing mechanical energy. In particular, CNTs exhibit great potential for fabricating flywheels to store kinetic energy with both high energy density and high power density, as discussed by Rufan Zhang, Fei Wei, and co‐workers in article number 1800680.
