PURPOSE:To reduce amount of binder and improve battery characeristic in nonaqueous electrolyte battery by utilizing an artificial graphite defining average interval of crystal layers and crystal particle diameter as the conductive agent of positive terminal where a metal oxide is used as the active substance. CONSTITUTION:For the positive terminal using a metal oxide such as manganese dioxide or metal sulfate and halogenide as the active substance, an artificial graphite in average interval of crystal layers of about 3.355Angstrom and crystal particle diameter of 1,000Angstrom or more is used as the conductive agent. A battery is assembled utilizing this positive terminal, negative terminal using a light metal (alloy) such as Li, Na and nonaqueous electrolyte. According to this battery, amount of binder used for the positive terminal can be reduced and amount of filler of positive terminal active substance can be increased. Thereby, liquid containing coefficient can be increased and battery performance can be as much improved. |
