An electrochromic device (10) of reversible light-transmissivity comprises a pair of spaced-apart window plate members (11, 13) bearing electrically-conductive surface layers (12, 14) and containing an electrochromotropic electrolyte solution in the intervening space (16). The electrolyte comprises an aqueous inorganic solution of a silver salt and may further comprise a salt of a transition metal. The electrolyte solutions are responsive to varying applied voltages by transitioning between solution phases of varying light-transmissivity which, depending upon solution composition, may be persistent or passively reversible.

Carbon nanostructures are used to prepare electrode compositions for lithium ion batteries. In one example, an anode for a Li ion battery includes three-dimensional carbon nanostructures made of highly entangled nanotubes, fragments of carbon nanostructures and/or fractured nanotubes, which are derived from the carbon nanostructures, are branched and share walls with one another. Amounts of carbon nanostructures employed can be less than or equal to 0.5 weight % relative to the weight of the electrode composition.
