摘要： A solid polymeric electrolyte having a pattern, and a lithium battery including the same, includes a polymer matrix having a mesh structure and being formed of a cured photo-crosslinking agent; inorganic particles substantially uniformly distributed in the polymer matrix; and a liquid electrolyte comprised of a lithium salt and an organic solvent impregnated between the polymer matrix and the inorganic particles. The liquid electrolyte and the cured photo-crosslinking agent are present in a weight ratio ranging from 50:50 to 99:1. The liquid electrolyte containing the cured photo-crosslinking agent and the inorganic particle are present in a weight ratio ranging from 10:90 to 90:10. The solid polymeric electrolyte has properties suitable for a printing process to provide the pattern including a thickness ranging from about 10 nm to about 500 μm and, prior to curing the photo-crosslinking agent, a viscosity ranging from 100-10,000 poise under a shear rate condition of 1 sec−1.

摘要： 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.
