Abstract:
1. A battery cell, comprising: a first electrode layer having a composition comprising a first polymer; a second electrode layer, having a composition comprising a third polymer, wherein said first polymer and said third polymer are different; a separator layer having a composition comprising a second polymer that has a melting point below tax of the first polymer and below that of the third polymer, the separator layer between the first and second electrode layers and having a first electrode-contacting surface and a second electrode-contacting surface; and a first current collector layer adjacent the first electrode layer at a surface opposite its separator-contacting surface, and a second current collector layer adjacent the second electrode layer at a surface opposite its separator-contacting surface; wherein the first and second electrode layers are each adhered to the separator layer at their respective first and second electrode-contacting surfaces, and the first and second current collector layers are each adhered to their respective first and second electrodes at the surfaces opposite their respective separator-contacting surfaces.
