An energy storage device comprises a first porous semiconducting structure ( 510 ) comprising a first plurality of channels ( 511 ) that contain a first electrolyte ( 514 ) and a second porous semiconducting structure ( 520 ) comprising a second plurality of channels ( 521 ) that contain a second electrolyte ( 524 ). In one embodiment, the energy storage device further comprises a film ( 535 ) on at least one of the first and second porous semiconducting structures, the film comprising a material capable of exhibiting reversible electron transfer reactions. In another embodiment, at least one of the first and second electrolytes contains a plurality of metal ions. In another embodiment, the first and second electrolytes, taken together, comprise a redox system. |
