NOVELTY - The lithium rechargeable battery comprises an electrode assembly (200) having a center pin (120). The center pin comprises a compression spring positioned within a thermal cut-off composition, a body surrounding the compression spring, a top lid blocking a top end of the body, and a bottom lid blocking a bottom end of the body. The thermal cut-off composition melts or explodes at 80-150 degrees C, and comprises a combination of two organic compounds. The top and bottom lids are opened or broken by a restoration force of the compression spring and comprise a polymer resin.    USE - The lithium rechargeable battery is useful for notebook personal computers, digital cameras and camcorders.    ADVANTAGE - The lithium rechargeable battery has improved thermal stability, high capacity and improved safety using the thermal cut-off composition, which can melt at a temperature of 80-250?0 C thus preventing the exploding and igniting of the battery.    DETAILED DESCRIPTION - The lithium rechargeable battery comprises an electrode assembly (200) having a center pin (120). The center pin comprises a compression spring positioned within a thermal cut-off composition, a body surrounding the compression spring, a top lid blocking a top end of the body, and a bottom lid blocking a bottom end of the body. The thermal cut-off composition melts or explodes at 80-150 degrees C, and comprises a combination of two organic compounds. The top and bottom lids are opened or broken by a restoration force of the compression spring and comprise a polymer resin. The body comprises a gasifier and a flame retardant. The gasifier decomposes at a predetermined voltage range to generate gas. The compression spring is inserted into the thermal cut-off composition by insert injection molding. The surface of the thermal cut-off composition is coated with a material.    DESCRIPTION OF DRAWING(S) - The diagram shows a sectional view of a battery.
