Abstract
Electrochemical cells and batteries including a polymeric support system in lieu of a conventional, metal-based structures. The polymer support system provides mechanical strength and mechanical flexibility to the electrochemical cells in a manner that is advantageously greater than what is provided by conventional structures, in spite of the fact that the polymer support system contributes far less to the overall weight of the electrochemical cells. The polymer support system may be present in an interior volume of an electrochemical cell, e.g., in the form of a continuous polymeric network penetrating various components of the electrochemical cell. The penetrating structures may include the anode and cathode current collectors, and any/all components therebetween. Additionally or alternatively, the polymer support system may include various forms of external support structures, chemical anchors, coatings and/or casings of the electrochemical cell. Additional advantageous characteristics include improved recyclability and increased longevity of the electrochemical cells.
