Also described is a method of manufacturing a charge storage device, the method comprising the steps of: providing a first electrode; disposing a second electrode in opposition to and spaced apart from the first electrode; disposing a porous separator between the electrodes; containing within a sealed package the electrodes, the separator and an electrolyte, wherein the electrodes are immersed in the electrolyte; and electrically connecting a first terminal and a second terminal to the first electrode and the second electrode respectively such that the terminals extending from the package to allow external electrical connection to the respective electrodes, wherein the gravimetric FOM of the device is greater than about 2.1 Watts/gram.

Charge storage device

A power supply is for an electrical load in the form of a Notebook computer. The power supply includes first terminals which extend from the computer for releasably electrically connecting with a first energy storage device in the form of a battery during a first interval. A second energy storage device, in the form a second battery, releasably electrically connects with terminals during a second interval spaced apart from the first interval. This allows power to be supplied to the load during those intervals. A capacitive energy storage device supplies power to the load during a third interval that spans the spacing between the first and the second intervals.

A power supply () for a pulsed load () includes a first energy storage device in the form of a battery () which is in parallel with a second energy storage device in the form of a supercapacitor (). Battery () and supercapacitor () are respectively modelled as: an ideal battery () in series with an internal resistance (); and an ideal capacitor () in series with an equivalent series resistance (ESR) (). Through use of a supercapacitor () having a low ESR with respect to the resistance (), the power supply () facilitates continuity of supply to load (). That is, during peak demand more of the load current will be supplied by supercapacitor () due to the lower ESR. Moreover, during times of lower load current demands the battery recharges the supercapacitor. This reduces the peak current needed to be provided by the battery and thereby improves battery longevity.

A charge storage device () includes a sealed prismatic housing (). Two opposed folded rectangular aluminium electrodes () are disposed within housing () and connected to respective metal terminals () for allowing external electrical connection to the electrodes. A porous, electronically insulating separator material, e.g. Solupor&#x2122;, sheet separator () is disposed intermediate electrodes () for maintaining those electrodes in a fixed spaced apart configuration. An electrolyte (not shown) is also disposed intermediate the electrodes. Collecting means in the form of a scavenging agent is grafted to separator () for sequestering one or more predetermined contaminants from the housing.

A charge storage device includes a layered strip which is folded lengthways along fold lines ( ) in the directions indicated by arrows ( ) to form a folded layered strip ( ). Strip ( ) is then cut to a predetermined length ( ). After the proportions of activated and conductive carbon, and the thickness of the paste, have been settled the length to which strip ( ) is cut is the final determining factor for the capacitance, time constant, power density and energy density of the charge storage device. The cut length ( ) is then folded crossways along fold lines ( ) in the directions indicated by respective arrows ( ) to form a twice folded structure ( ).
