NOVELTY - A negative electrode comprises a current collector and a negative-electrode active material layer bonded to the current collector. The negative-electrode active material layer comprises negative-electrode active material particles containing silicon oxide (I), bonding portion for bonding the negative-electrode active material particles with each other and bonding the negative-electrode active material particles with the current collector, and polymer coating layer for coating at least portion of surfaces of negative-electrode active material particles.    USE - Negative electrode is used for nonaqueous secondary battery (claimed)e.g. lithium-ion secondary battery. Uses include but are not limited to drive motors of electric vehicles and hybrid vehicles, personal computer, mobile communication equipment, domestic electrical appliances, office equipment and industrial equipment.    ADVANTAGE - The nonaqueous secondary battery provided with the negative electrode has high capacity and battery characteristics even after repeated charge and discharge, and suppressed reductive decomposition of electrolyte or electrolytic solution and increase in resistance.    DETAILED DESCRIPTION - A negative electrode comprises a current collector and a negative-electrode active material layer bonded to the current collector. The negative-electrode active material layer comprises negative-electrode active material particles containing silicon oxide of formula: SiOx (I) (where x is 0.5-1.6), bonding portion for bonding the negative-electrode active material particles with each other and bonding the negative-electrode active material particles with the current collector, and polymer coating layer for coating at least portion of surfaces of negative-electrode active material particles. The polymer coating layer contains cationic polymer having positive zeta potential under neutral conditions. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of negative electrode; and    (2) nonaqueous secondary battery.
