Macroreticular carbonaceous material useful in energy storing devices
First Claim
1. An energy storage device comprising a macroreticular carbonaceous material having a distribution of micropores, mesopores and macropores wherein the macroreticular carbonaceous material has a total porosity of at least 1.0 cm3/g, a total surface area of from greater than 500 m2/g to 2500 m2/g and wherein 20% to 80% of the total surface area is due to pores with diameters of from 17 angstroms to 100,000 angstroms;
- wherein the distribution of micropores, mesopores and macropores is bimodal;
wherein measurement of pore size distribution of the macroreticular carbonaceous material yields a first distinct peak representing a pore size of less than or equal to 20 angstroms when measured utilizing H-K dv/dlog(W) pore size distribution and a second distinct peak representing a pore size greater than 100 angstroms when measured utilizing BJH dv/dlog(D) pore size distribution;
wherein micropores have diameters less than 20 angstroms, mesopores have diameters from 20 to 500 angstroms and macropores have diameters greater than 500 angstroms.
