  • Lithium rechargeable battery having functional center pin
    Patent number: 7785732
    Abstract: 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.
    Type: Grant

  • Lithium rechargeable battery with functional center pin
    Patent number: 7749642
    Abstract: 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.
