| 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. Such a lithium secondary battery may prevent a short circuit between the ceramic film-coated electrode plates and the electrode collector of electrode plates having different polarities, when the ceramic film-coated electrode plates are laminated or spirally wound, thereby improving stability and reliability of the battery. |
