UNIFICATION-TYPED ELECTRODE ASSEMBLY AND SECONDARY BATTERY USING THE SAME

摘要

PURPOSE: A one-body type electrode assembly is provided to prevent short due to contraction of a separator, and to impregnated electrolyte into an electrode, thereby capable of solving problems of poor electrode uniformity, and process time increase. CONSTITUTION: A one-body type electrolyte(100) comprises a positive electrode(110), a negative electrode(120), and a three-phase separator layer(130). The tree-phase separator layer is between the positive electrode and the negative electrode, and consists of a liquid component comprising an ionic salt, a solid component supporting the separator layer between the positive electrode and the negative electrode, and a polymer matrix in which a linear polymer and a crosslinkable polymer form a viscoelastic structure in state the liquid component and the sold component are mounted. The polymer matrix is respectively combined with the positive electrode and the negative electrode.
