NOVELTY - A nanoporous energy chip comprises a conductive material, where the conductive material is monolithic and contains an open network of pores having an average pore diameter of 0.3-30 nm, and where the conductive material forms a thin chip having a thickness of less than or equal to 300 microns, and where the thickness across different portions of the chip varies by less than 10% of the thickness of the chip. The energy chip also comprises an electrolyte in the open network of pores.    USE - As nanoporous energy chip which is useful in energy storage device, asymmetric ultracapacitor, capacitor, electric double layer capacitor, battery, and fuel cell (claimed).    ADVANTAGE - The energy chip has conductive surface area of at least 2000 m2/g; and has thickness across different portions of less than 5%.
