Claim 21:
22. An electrode for an electrochemical cell formed by exposing a substrate to a flux of at least 1012 carbon ions per cm2 of substrate per 1 ms, a majority of the carbon ions having a kinetic energy of at least 20 eV to provide a carbon material comprising sp2 and sp3 hybridized carbon having a plurality of differentially sized pores to provide a specific lithium storage capacity of at least 1700 mAh/g, the carbon material comprising at least one area with a plurality of regularly arranged, graphene-like layers of carbon, the at least one area being embedded in amorphous carbon, the percentage of sp2 type carbon is at least 25 weight % based on the total weight of the carbon material, the percentage of sp3 type carbon is at least 20 weight % based on the total weight of the carbon material, the flux being provided in a plurality of pulses such that the carbon ions contact the substrate in less than 50 μs, a relaxation time between each of the plurality of pulses being at least 100 μs, and the temperature of the substrate being less than 60° Celsius.
