PURPOSE:To lengthen the charge-discharge cycle life and to increase the overdischarge resistant performance by using a substance prepared by quickly cooling a molten mixture of vanadium pentoxide and ammonium phosphate trihydrate in a positive electrode and a molding of a specific carbon powder in a negative electrode. CONSTITUTION:A positve electrode 1 is a molding of amorphous material powder prepared by melting a mixture of V2O5 and (NH4)3PO44.3H2O, and quickly cooling the molten mixture. The mole ratio of (NH4)3PO4.3H2O to V2O5 is specified to 45% or less. A negative electrode is made of carbon having a hydrogen-to-carbon ratio of less than 0.15, an X-ray wide angle diffraction spacing of 3.37Angstrom or more, and a C-axis direction crystallite size of 150Angstrom or less. |
