| 摘要 |
The present invention relates to a lithium secondary battery, including a positive electrode, a negative electrode, a separation layer inserted between the positive electrode and the negative electrode and a non-aqueous electrolyte solution where the provided lithium secondary battery includes an ionomer denoted by chemical formula 1 among at least one component selected from a group consisting of the positive electrode, the negative electrode, the separation layer and the non-aqueous electrolyte solution. In chemical formula 1, A and B are separately H,F, CH_3 or CF_2 wherein the mole ratio of -CF-O-(CF_2)_2-SO_3^-Li^+and -CF_2- is between 0 to 90 and 10 to 100, and k is at least one integer. |
