The present disclosure relates to a gel electrolyte composition including a fluorine-containing copolymer including repeating units represented by following Formula 1 and following Formula 2, lithium salt, and an organic solvent, and a secondary battery including the same.
Claims17
A gel electrolyte composition comprising:
- a fluorine-containing copolymer including repeating units represented by following Formula 1 and following Formula 2;
- lithium salt;
- and
- an organic solvent,
- in which, in Formula 1, A1 is *—C(═O)—*, *—C(═O)O—* or *—S(═O)2—*.
- each of R1, R2 and R3 is independently hydrogen or C1-C6 straight-chain or branched-chain alkyl, respectively,
- X is *—F,
- each of D1, D2, D3 and D4 is which is one independently selected from hydrogen, fluorine, C1-C6 straight-chain or branched-chain alkyl, and fluorinated C1-C6 straight-chain or branched-chain alkyl,
- D5 is one selected from fluorine, fluorinated C1-C12 straight-chain or branched-chain alkyl, and fluorinated C1-C12 straight-chain or branched-chain alkoxy,
- D6 is one selected from hydrogen, fluorine, fluorinated C1-C12 straight-chain or branched-chain alkyl, and fluorinated C1-C12 straight-chain or branched-chain alkoxy,
- ‘n’ is an integer ranging from 0 to 20, and
- ‘y’ is an integer ranging from 1 to 5,
- in which, in Formula 2,
- R4, R5 and R6 are each independently hydrogen or C1-C6 straight-chain or branched-chain alkyl, and
- A2 is C1-C6 straight-chain or branched-chain alkylene.
