About Carbon nanotube springs energy storage

Carbon nanotube springs are springs made of carbon nanotubes (CNTs). They are an alternate form of high-density, lightweight, reversible energy storage based on the elastic deformations of CNTs. Many previous studies on the mechanical properties of CNTs have revealed that they possess high stiffness, strength.

Springs for energy storage can be made of SWCNTs or MWCNTs arranged in dense bundles of long, aligned tubes called "forests" of CNTs that are grown by(CVD). The "forests" can grow.

A CNT spring made of bundles of densely packed 1 nm diameter SWCNTs stretched to a 10% strain is predicted to have an energy density of 3.4×10kJ/m . The energy density of.
