Abstract: An electrolyte composition, quasi-solid-state electrolyte, and lithium-ion battery employing the same are provided. The electrolyte composition includes a component (A), component (B) and component (C). The component (A) is a combination of a first polymer (A1) and a second polymer (A2), or a third polymer (A3). The first polymer (A1) has a repeating unit of Formula (I), the second polymer (A2) has a repeating unit of Formula (II), and the third polymer (A3) has a repeating unit of Formula (I) and a repeating unit of Formula (II)










, wherein R1, R2, R3, R4, R5, Z1, and Z3 are as defined in the specification. The component (B) is a lithium salt and the component (C) is a solvent.
