Nanochargers: Energetic materials for energy storage

Nanochargers are energetic materials consisting of fuel metal particles and metallic oxide particles that absorb and store energy up to an ignition threshold. Once ignited a controlled exothermic reaction ensues producing energy. Nanotechnology has spurred the understanding of unique nanoparticle combustion behaviors that enable creation of nanochargers with optimized heat capacity for storing energy. Although in the initial stages, these experiments demonstrate evidence of the nanocharger's potential for energy storage and transfer. (C) 2009 American Institute of Physics. [doi:10.1063/1.3263721]
