Abstract:
(EN) The present invention relates to a silicon-carbon-based composite anode active material, an anode for a secondary battery comprising the same, and a lithium secondary battery and, more specifically, to a silicon-carbon-based composite anode active material which comprises: a carbon-based core capable of absorbing and emitting lithium ions; and at least one silicon particle contained in the carbon-based core and arranged to be distributed in the outer periphery of the carbon-based core, and which thereby has improved physical stability, and to a cathode for a secondary battery, and a lithium secondary battery having improved lifespan characteristics by including the anode active material.
(FR) La présente invention porte sur un matériau actif d'anode composite à base de silicium-carbone, une anode pour accumulateur le comprenant, et un accumulateur au lithium, et plus précisément sur un matériau actif d'anode composite à base de silicium-carbone qui comprend : un cœur à base de carbone susceptible d'absorber et de désorber des ions lithium ; et au moins une particule de silicium contenue dans le cœur à base de carbone et agencée pour être distribuée dans la périphérie extérieure du cœur à base de carbone, et qui présente de ce fait une stabilité physique améliorée, et sur une cathode pour accumulateur et un accumulateur au lithium ayant des caractéristiques de durée de vie améliorées par inclusion du matériau actif d'anode.
