Abstract
An activated carbon powder comprising activated carbon particles that comprise D-band carbon corresponding to a sphybridized disordered carbon phase and G-band carbon corresponding to a sphybridized graphitic phase at a controlled proportion. Additionally, the activated carbon particles comprise nitrogen at an amount that is in a range of about 0.3 atomic % to about 1.8 atomic % of the activated carbon particles, wherein at least some of the nitrogen atoms are substituted for carbon atoms in the crystal lattice structure of the G-band carbon. Also, the carbon particles have a surface area that is in a range of about 900 m/g to about 2,500 m/g, an average pore width in a range of about 1 nm to about 4 nm, a microporous surface area in a range of about 300 m/g to about 1,350 m/g, and a cumulative surface area of pores with a hydraulic radius in a range of 0.285 nm to 1.30 nm that is in a range of about 1,000 m/g to about 3,000 m/g.
