Abstract:
A supercapacitor structure formed as a unitary flexible laminate structure comprising:a) a first electrode member of first polarity, comprising a flexible polymeric matrix membrane having an activated carbon powder uniformly distributed therein and an electrically conductive current collector element;b) a first separator member, comprising a flexible, polymeric matrix membrane, said first separator member bonded to said first electrode member;c) a second electrode member of second polarity opposite said first polarity, comprising a flexible polymeric matrix membrane having an activated carbon powder uniformly distributed therein and an electrically conductive current collector element, said second electrode member bonded to said first separator member opposite said first electrode member;d) a second separator member, comprising a flexible, polymeric matrix membrane, said second separator member bonded to said second electrode member opposite said first separator member; ande) a third electrode member of said first polarity, comprising a flexible polymeric matrix membrane having an activated carbon powder uniformly distributed therein and an electrically conductive current collector element, said third electrode member bonded to said second separator member opposite said second electrode member.
