1. A power system adapted for supplying power in a high temperature environment, the power system comprising:
a rechargeable energy storage that is configured to store between about one tenth (0.1) of a joule and about one hundred kilojoules of energy, and to provide peak power of between about one watt and about one hundred kilowatts, for at least two charge-discharge cycles; rechargeable energy storage being coupled to a circuit for at least one of supplying power from the energy storage and charging the energy storage; and
wherein the rechargeable energy storage comprises an ultracapacitor comprising an electrochemical double-layer capacitor comprising:
two electrodes wetted with an electrolyte, each electrode being attached to or in contact with or coated onto a current collector and separated from each other by a separator porous to the electrolyte, wherein the electrodes comprise activated carbon, carbon fibers, rayon, graphene, aerogel, carbon cloth, carbon nanotubes and another nano-form of carbon; wherein the electrolyte comprises a plurality of cations and a plurality of anions, the cations comprising at least one of 1-(3-cyanopropyl)-3-methylimidazolium, 1,2-dimethyl-3-propylimidazolium, 1,3-bis(3-cyanopropyl)imidazolium, 1,3-diethoxyimidazolium, 1-butyl-1-methylpiperidinium, 1-butyl-2,3-dimethylimidazolium, 1-butyl-3-methylpyrolidinium, 1-butyl-4-methylpyridinium, 1-butylpyridinium, 1-decyl-3-methylimidazolium, 1-ethyl-3-methylimidazolium and 3-methyl-1-propylpyridinium; the anions comprising at least one of bis(trifluoromethanesulfonate)imide, tris(trifluoromethanesulfonate)methide, dicyanamide, tetrafluoroborate, hexafluorophosphate, trifluoromethanesulfonate, bis(pentafluoroethanesulfonate)imide, thiocyanate, and trifluoro(trifluoromethyl)borate;
wherein the ultracapacitor exhibits a leakage current less than 1 amp per liter of volume over a range of operating temperatures and at a voltage up to a rated voltage; and
a power supply; where the power supply is configured to supply energy from an energy storage to a logging instrument.
