Lithium Secondary Battery And Manufacturing Method Therefor
Abstract: The present invention relates to a lithium secondary battery comprising: an anode comprising a silicon-based anode active material; a cathode; a separator interposed between the cathode and the anode; and an electrolyte, wherein the silicon-based anode active material comprises 30 parts by volume or less of crystalline silicon on the basis of 100 parts by volume of the total weight of the active material, and breakage of silicon-based anode active material particles is minimized such that side reactions with an electrolyte solution and electrode degradation are inhibited, and thus lifespan characteristics and resistance characteristics are improved.
