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： A center pin and a lithium ion secondary battery are provided. The center pin has a hollow body and a solid extinguishant is disposed inside the hollow body. The solid extinguishant has a certain shape that can fit into the hollow body, and can be made by compressing a powder extinguishing substance. Top and bottom of the center pin are initially closed by blocking members to reduce a dead volume in a battery. The top and bottom of the center pin open at high temperature so that the solid extinguishant is liquefied and flows out of the center pin. The liquefied extinguishant at the high temperature prevent the battery from igniting.
