Provided are a polymer electrolyte and a lithium-ion battery including the polymer electrolyte. A preparation method of a polymer electrolyte includes: (1) dissolving a functional polymer with an organic solvent, and uniformly mixing to obtain a system A, where the functional polymer has a mass ratio of 0.2%-30% in the system A; (2) uniformly mixing the A system, a lithium salt, and a functional additive to obtain a mixed solution; (3) subjecting the mixed solution to in-situ polymerizing to obtain the polymer electrolyte. The polymer electrolyte has better affinity with anions of the lithium salt and relatively high electrical conductivity, and greatly improves the performance of the semi-solid state battery. The semi-solid state battery prepared is based on the existing lithium-ion battery processing technology, has good processing performance and electrochemical performance, and has certain application prospects.
