摘要： Disclosed is a method for producing a lithium secondary battery including forming an electrode assembly using a cathode, an anode and a separator, introducing the electrode assembly into a battery case, injecting an electrolyte into the battery case, and sealing the battery case, wherein, during assembly of the electrode assembly, insulating particles are dispersed on part of the surface of the separator, or at least one of the cathode and the anode contacting the separator. The step of dispersing insulating particles on the part of the surface of the separator or at least one of the cathode and the anode contacting the separator during battery assembly can considerably reduce short-circuits in a lithium secondary battery caused by intrinsic and extrinsic factors and thus low-voltage defects, and thereby significantly improve yield of a lithium secondary battery.

摘要： Provided is a cathode mix for lithium secondary batteries, comprising a cathode active material having a composition represented by the following Formula I: LiFe(P1-XO4) (I) wherein a molar fraction (1−x) of phosphorus (P) is in the range of 0.910 to 0.999, to allow operational efficiency of the cathode active material to be leveled to a lower operational efficiency of an anode active material and improve energy density of the cathode active material.The cathode mix maximizes operational efficiency of batteries, minimizes electrode waste and thus reduces manufacturing costs of batteries. Furthermore, The cathode active material, wherein a molar fraction (1−x) of phosphorus (P) is lower than 1, according to the present invention contains both Fe2+ and Fe3+, thus advantageously causing no structural deformation, improving ionic conductivity, exhibiting superior rate properties, inhibiting IR drop upon charge/discharge, thereby imparting high energy density to batteries.
