Charge storage device

A charge storage device including:

• a charge storage cell including:
• (a) a first electrode having a first layer including a carbon having a surface area greater than 400 m2/gram;
• (b) a second electrode having a second layer including a carbon having a surface area greater than 400 m2/gram;
• and
• (c) a porous separator disposed between the electrodes;
• a sealed package for containing the cell and an organic electrolyte in which the cell is immersed, wherein the first and second layers are opposed and spaced apart;
• and
• at least two terminals that extend from the package to allow external electrical connection to the cell, wherein the volumetric FOM (Figure of Merit) of the device is greater than about 1.1 Watts/cm3 and the device has a maximum thickness of less than about 7 mm.
