PURPOSE: A block copolymer is provided to be manufactured through a relatively simple synthetic process, and to provide a polymer electrolyte capable of simultaneously ensuring mechanical stability and high ion conductivity. CONSTITUTION: A block copolymer(A-B) comprises: a first block(A) which comprises a polyalkylene oxide-grafted vinyl polymer, and a vinyl aromatic hydrocarbon polymer substituted by a hydroxy group; a second block(B) which is a vinyl aromatic hydrocarbon polymer substituted by hydroxy group. The vinyl polymer is substituted by one or more functional group selected from an imide group and amide group, and a carboxy group. The electrolyte composition comprises the block copolymer. A semi-solid electrolyte is formed by hardening an electrolyte composition comprising the block copolymer through an UV-irradiation. |
