ELECTRODE MATERIAL AND METHOD FOR PRODUCING THE SAME
摘要
An electrode material suitable for high capacitance and large-current discharge and used for electric double layer capacitors and cells is characterized in that a very sharp pore size distribution is displayed in a mesopore region, and the volume of pores having pore sizes of X +/- alpha nm (3.0</=X<10, alpha = 1.0: the distribution range of pore size) accounts for more than 15 % of the total volume of mesopores having pore sizes ranging from 2.0 to 50 nm. The electrode material is produced by adding at least one kind of a transition metal and its compound to a carbonaceous material or a carbon precursor and heating the mixture to 600 DEG C or more.
