ABSTRACT:
An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive (20) and a negative (30) electrode and the electrolyte system (40) disposed there between. The electrolyte system includes a liquid electrolyte adapted to provide ion transport between the positive and negative electrodes and a segmented block copolymeric support structure for engaging the liquid electrolyte.
