Claims16
A polymer electrolyte for a secondary battery, the polymer electrolyte comprising:
- a lithium salt;
- and
- unit A derived from polymer (a) represented by Formula 1:
- wherein, in Formula 1,
- R1, R2, and R3 are each independently hydrogen or —CH2—CH═CH2,
- at least one of R1, R2, and R3 is —CH2—CH═CH2,
- each of a, b, and c is the number of repeating units, and
- a, b, and c are each independently an integer of any one of 1 to 10,000, and
- wherein a weight ratio of the lithium salt to the unit A derived from the polymer (a) represented by Formula 1 is in a range of 1:1 to 1:9.
