PURPOSE: To obtain a battery excellent in discharge capacity and in discharge efficiency when discharging a big current as well as in dimensional stability by using a porous carbon substance mainly composed of a mixture of carbon black and acetylene black having chain structure in which a graphite crystal thin film is formed around particles.
CONSTITUTION: The negative pole 2 made of any one light metal of lithium, natrium and alminium as well as the positive pole 3 composed of a porous carbon substance 7 and a metal collector 6 are provided in a can 1 through a separator 4, while housing an electrolyte having oxyhalogenated sulphur as the main positive pole active substance in the can 1. The substance mainly composed of carbon black having chain structure, in which a graphite crystal thin film is formed around particles, is used as the porous carbon substance 7 in said nonaqueous solvent battery. A blending ratio of said carbon black and acetylene black is desirable 20∼80wt% of carbon black and 80∼20wt% of acetylene black.
