Abstract: A polymer solid electrolyte having high ion conductivity and interfacial stability. By the polymer solid electrolyte comprising an additive having excellent reachability to a positive electrode surface, and properties of facilitating film formation in a positive electrode due to low oxidation potential, a film is readily formed on the positive electrode surface, and as a result, a lithium secondary battery having enhanced performance may be provided.
