摘要： A lithium secondary battery includes two electrode plates having different polarities and has a ceramic film provided on one electrode plate of the two, wherein the electrode plate coated with the ceramic film has a front edge positioned ahead of a front edge of another electrode plate, and/or has a back edge positioned behind a back edge of the other electrode plate when the two electrode plates are laminated and/or spirally wound. Aspects of the present invention provide such a lithium secondary battery to prevent a short circuit between the ceramic film-employed electrode plates and the electrode collector of electrode plates having different polarities when the ceramic film-employed electrode plates are laminated or spirally wound, thereby improving stability and reliability of the battery.

摘要： A jelly roll electrode assembly, including a ceramic separator instead of a film separator and a secondary battery using the assembly, can be easily wound by forming a long non-coating portion of plate instead of the film separator to prevent cross-winding of the electrode assembly and the mandrel due to a friction by separating the wound electrode assembly from the mandrel, and to improve reliability. The jelly roll electrode assembly, including a positive electrode plate and an negative electrode plate, includes: a ceramic layer coated on at least one of the positive electrode plate or the negative electrode plate to prevent an electrical short between the positive electrode and negative electrode plates; a non-coating portion of the positive electrode and negative electrode plates, having no active material coated thereon, and an extended contact part, of the same electrode material as the non-coating portion, extending from one end of the non-coating portion of the positive electrode plate or the negative electrode plate to contact a mandrel during winding of the assembly.
