ABSTRACT:
The present invention relates to lignocellulosic-based carbon-containing double layer energy storage devices having improved electrical energy densities. In particular, the invention provides a double layer energy storage cell comprising a pair of electrodes, at least one of which is a carbon paste electrode, a porous ionically conductive separator, and an ion insulating collector, the improvement wherein said carbon paste electrode includes an activated lignocellulosic-based carbon having a pore volume of greater than about 0.45 cc/g, a median pore width of less than 2.0 nm, a specific surface area of greater than about 500 m.sup.2 /g, and a micropore content, based on the total particle volume of the activated carbon, of greater than about 75%.
