Rechargeable lithium battery construction

A rechargeable battery construction comprising a plurality of electrolytic cells of which each cell comprises a positive electrode member, a negative electrode member, and a separator member disposed therebetween, said members having flexible, self-supporting, polymeric matrix film composition and being bonded to contiguous members at respective interfaces to form a unitary flexible laminate cell,

• characterized in that
• a) the respective like-polarity electrodes of at least two of said cells are disposed contiguously within said construction;
• and
• b) the members of said two cells are arranged in continuous concentrically overlapping layers.

• characterized in that
• a) each of said electrode members comprises an electrolytically active composition element and an electrically conductive collector element;
• b) at least one of said collector elements of each cell is permeable to a fluid electrolyte;
• c) the respective like-polarity collector elements of at least two of said cells are disposed contiguously within said construction;
• d) the members of said two cells are formed into a structure having a continuous concentrically overlapping layer arrangement;
• e) said permeable collector elements comprise the cell layers disposed closest to the interior of said overlapping arrangement structure;
• and
• f) a respective one of opposite-polarity collector elements of said cells is disposed at the outer surface of said structure.
