STACK-FOLDING-TYPE ELECTRODE ASSEMBLY

摘要

The present invention can provide an electrode assembly having a structure in which multiple unit cells overlap one another, the respective overlapping parts having a continuous folding separator interposed therebetween, the stack-folding-type electrode assembly being characterized in that the continuous folding separator comprises: a continuous porous polymer substrate having pores; and organic-inorganic porous coating layers, which are formed of a mixture of an inorganic particle and a binder polymer, discontinuously at the overlapping parts, the stack-folding-type electrode assembly facilitating electrolyte impregnation and having a reduced volume in comparison with conventional electrode assemblies.
