摘要： Provided are a method for forming a cathode active material powder for a lithium secondary cell, and a cathode active material powder prepared using the method. According to the method, a coating layer consisting of a combination of a water-soluble polymer and a metal oxide may be formed on the particle surface of the cathode active material, thereby forming a uniform thickness of the coating layer. Thus, the elution of manganese may be prevented, thereby improving the capacity of the cathode active material and providing excellent cycle characteristics.

摘要： Provided are a composite polymer electrolyte for a lithium secondary battery in which a composite polymer matrix multi-layer structure composed of a plurality of polymer matrices with different pore sizes is impregnated with an electrolyte solution, and a method of manufacturing the same. Among the polymer matrices, a microporous polymer matrix with a smaller pore size contains a lithium cationic single-ion conducting inorganic filler, thereby enhancing ionic conductivity, the distribution uniformity of the impregnated electrolyte solution, and maintenance characteristics. The microporous polymer matrix containing the lithium cationic single-ion conducting inorganic filler is coated on a surface of a porous polymer matrix to form the composite polymer matrix multi-layer structure, which is then impregnated with the electrolyte solution, to manufacture the composite polymer electrolyte. The composite polymer electrolyte is used in a unit battery. The composite polymer matrix structure can increase mechanical properties. The introduction of the lithium cationic single-ion conducting inorganic filler can provide excellent ionic conductivity and high rate discharge characteristics.
