摘要： Lithium rechargeable batteries having functional center pins are provided. A lithium rechargeable battery has a center pin whose top and bottom ends are blocked by a thermal cut-off composition to reduce the void volume inside a bare cell during initial overcharge. The thermal cut-off composition melts at a temperature within a specific temperature range, e.g. between about 80 and about 250° C. This prevents the battery from exploding and igniting. Thus, the inventive lithium rechargeable batteries have improved thermal stability.

摘要： Lithium rechargeable batteries having functional center pins are provided. A lithium rechargeable battery has a center pin having a compressed compression spring positioned within a thermal cut-off composition to reduce the void volume inside a bare cell during initial overcharge. The thermal cut-off composition melts at a temperature within a specific temperature range, e.g. between about 80° C. and about 250° C. This prevents the battery from exploding and igniting. Thus, the inventive lithium rechargeable batteries have improved thermal stability.

摘要： A cylinder type lithium ion secondary battery has a center pin that is inserted into an electrode assembly after the injection of electrolyte to increase impregnation of the electrolyte. The battery includes an electrode assembly, a case to accommodate the electrode assembly, a center pin inserted into the center of the electrode assembly, a cap assembly to seal an upper end opening of the electrode assembly, and an upper insulating plate disposed between the electrode assembly and the cap assembly. The upper insulating plate has a hollow formed in the center through which the center pin can penetrate, and the hollow has a center pin separation preventing unit bendable only toward the electrode assembly when the center pin penetrates through the hollow.
