A solid polymer electrolyte according to the present invention can have a pattern and various shapes. The solid polymer electrolyte can be made to control the properties of electrolyte paste by controlling the composition ratio of liquid electrolyte, a photo-crosslinking agent and inorganic particles, dispersion and thickness thereof. The solid polymer electrolyte having a pattern can be manufactured from the electrolyte paste through a printing process which can simplify a method for manufacturing a lithium battery. The solid polymer electrolyte can improve, despite the shape thereof, the performance of a lithium battery such as improved interfacial stability between an electrode and the electrolyte, and the inhibited internal short circuit of the lithium battery.
