NEGATIVE ELECTRODE FOR LITHIUM SECONDARY CELL AND METHOD FOR PRODUCING THE SAME

摘要

A negative electrode for a lithium secondary cell, characterized in that it is prepared by a method comprising providing a conductive metal foil having a surface roughness of 0.2 ñm or more as a collector and a mixture of active material particles containing silicon and/or a silicon alloy with a conductive metal powder and sintering the mixture on the surface of the collector; and a a lithium secondary cell comprising the negative electrode.
