NOVELTY - The apparatus e.g. supercapacitor has first electrode (503) and second electrode (502) separated by a polymer electrolyte (517,518). One or both of the first and second electrodes has actuating substrate (519,520) configured to undergo reversible deformation during actuation and that contains and elastomer. The electrode has active material on or within actuating substrate. The reversible deformation of actuating substrate causes a decrease in internal resistance of the apparatus by increasing the area of contact between active material of electrode and electrolyte.    USE - Apparatus e.g. battery, supercapacitor, or battery-capacitor hybrid for electronic device (claimed) e.g. personal digital assistant (PDA).    ADVANTAGE - The deformation of electrical storage apparatus is used to recover the sub-threshold energy and provide additional power to the device when open circuit voltage of the electrical storage apparatus drops below the threshold potential of device since reduction in the internal resistance increases the open circuit voltage of the battery. The reversible deformation allows recover of the sub-threshold energy after each discharge if need be. The risk of breakage is minimizes as a result of inherent flexibility since membrane is made from the same elastomer as the bulk of the actuating substrate. Allows heating element to be pulsed rapidly for expanding and contracting the actuating substrate while minimizing the overall power consumption since temperature is dropped back down to predetermined value once the flow of current was stopped. Ensures reduced requirement to download data when further functionality is required for the device since device is pre-programmed with appropriate software enabled for use by user downloading a key to unlock/enable the software and its associated functionality.    DETAILED DESCRIPTION - The active material includes at least one of graphene, graphene platelets, silver nanowire mesh, silicon nanowires, carbon nanotubes, and a metal oxide slurry. INDEPENDENT CLAIMS are included for the following:    (1) a method for making a reversibly deformable electrical storage apparatus; and    (2) a method for controlling the making and/or use of reversibly deformable electrical storage apparatus.
