PURPOSE: An electrode assembly is provided to prepare a secondary battery with excellent internal short circuit and capability by limiting the content of a binder of a porous membrane formed by bonding a ceramic material and a binder. CONSTITUTION: An electrode assembly comprises a positive electrode containing a positive electrode active material layer, a negative electrode containing a negative electrode active material layer, and a separator separating the positive electrode and negative electrode. The negative electrode active material layer comprises a metal material capable of alloying lithium or lithuim vanadium oxide(LiV3O5). The separator comprises a porous film formed by the ceramic material and binder. |
