  • Packing structure for lithium ion polymer battery
    Patent number: 8980466
    Abstract: Disclosed is a packing structure for a lithium ion polymer battery, which includes: a battery casing including a lower multilayer polymer and an upper multilayer polymer, wherein the lower multilayer polymer has an inner space of a predetermined size for housing at least one electrode assembly and an electrolyte and is provided with an extension portion extending radially and outwardly from a top edge of each vertical portion of the lower multilayer polymer, a part of the upper multilayer polymer is coupled rotatably to a part of the extension portion of the lower multilayer polymer and remaining parts of the upper multilayer polymer are sealed to remaining parts of the extension portion of the lower multilayer polymer; and a battery protection member, which wraps the outer circumference of the battery casing so that the battery contained in the battery casing can be protected from external impact, and is fixed integrally by a part of the sealed extension portions.
