ABSTRACT:
A nonaqueous secondary cell comprises at least one pair of electrodes, and a separator provided between the at least one paired electrodes and impregnated with a nonaqueous electrolyte containing a mixed solvent of propylene carbonate and ethylene carbonate. At least one electrode of the at least one paired electrodes has, at least on surfaces thereof, an active substance layer made of composite carbon particles, which individually comprise a core of crystalline carbon and a low crystallinity or amorphous carbon layer formed on at least a part of the surfaces of the core, and a carbon matrix covering at least a part of the composite carbon particles and uniformly dispersing and holding the composite carbon particles therein.
