PURPOSE:To provide an electrode body excellent in conductivity in which the characteristic of carbon fiber electrode is efficiently used. CONSTITUTION:To 40g. of carbon fiber aggregate of a PAN 1500 deg.C sintered bobbin wound product about 7mum-8mum thick, 60g. of a commercially available lead fiber felt about 100mum thick and 50wt.% of lead sulfate as a positive electrode material or negative electrode material are mixed followed by pressure molding. Thus, conductivity is improved without losing the characteristic of carbon fiber electrode, and charge/discharge efficiency is remarkably improved. |
