Abstract
A negative electrode comprises carbon particles which individually consist of a core of crystalline carbon and an amorphous carbon layer formed on at least a part of the surfaces of the core, and an amorphous carbon matrix dispersing the carbon particles therein. The carbon matrix is formed by thermal decomposition of a thermosetting resin. A non-aqueous electrolyte secondary cell which comprises an electrode of the type mentioned above as at least one of electrodes is also described.
