Abstract: Provided are a solid polymeric electrolyte and a lithium battery with the same. The electrolyte paste may be formed by controlling composition ratio, dispersion, and thickness of the electrolyte paste to have physical properties suitable for the printing process. The use of the printing process enables to simplify a process of fabricating the lithium battery. In addition, the lithium battery provided with the solid polymeric electrolyte can exhibit improved performance (for example, in electrode-electrolyte interface stability and an internal short property), regardless of the shape of the solid polymeric electrolyte. For example, the lithium battery may exhibit improvement in interface stability between the electrode and the electrolyte and be configured to suppress an internal short therein.
