PPROBLEM TO BE SOLVED: To provide a lithium secondary battery using a lithium based composite oxide as a positive electrode active material or a negative electrode active material, and having excellent cycle characteristics, quick charge and discharge characteristics, and preservation stability. PSOLUTION: This lithium-ion secondary battery uses the lithium based oxide subjected to surface treatment with a surface treating agent expressed by a general formula (1): MSP1/SPSB(a)/SBXSB(b)/SB(1) (in the formula, MSP1/SPis a polyvalent cation of one or more than two kinds among Mg, Ca, Sr, Ba, Zn, Al, Ge, Ti, and Zr. X is an anion of lithium salt for electrolyte of a lithium secondary battery. a0, and b0 ). PCOPYRIGHT: (C)2010,JPO&INPIT
