Abstract
For us in nonaqueous electrolyte secondary cells, the invention provides an electrode which comprises a first carbon material serving as a core material, and a second carbon material coating the first carbon material over the surface thereof and containing boron. When used as an active substance for negative electrode to provide a nonaqueous electrolyte secondary cell, the electrode diminishes the reduction of the cell capacity that would result if the cell is allowed to store, giving improved storage characteristics to the cell.
