1. A nanoporous carbon material comprising:
a plurality of interconnected carbonized struts having a strut width of from 2 nm to 10 nm;
a plurality of pores defined by the plurality of interconnected carbonized struts, wherein:
the plurality of pores is characterized by a pore size distribution, the pore size distribution having a full width at half max of from 5 nm to 50 nm; and
the plurality of pores is characterized by a pore size of 70 nm or less at a maximum peak of the pore size distribution.
