Abstract
Stone Wales defect pairs in a carbon nanostructure are used to store energy. Energy is released by a chain reaction of phonons disrupting the defect pairs to generate more phonons until the lattice returns to its original hexagonal form and the energy is released in the form of lattice vibrations. Devices may be configured as a battery to release electrical energy in a controlled manner or as an explosive to release energy in an uncontrolled manner.
