  • Patent number: 10727471
    Abstract: A method for manufacturing a lithium ion polymer battery is provided in which in injecting electrolyte into a lithium ion polymer battery, the battery cell is immersed in an electrolyte impregnation bath to allow the electrolyte to be impregnated into the cell. The electrolyte can be impregnated simultaneously, and as the battery cell is activated, the electrolyte is settled down in the interior of the battery cell. Thus, when the battery cell is sealed, a phenomenon that the electrolyte is present at the sealed portion can be prevented.

  • Patent number: 8043743
    Abstract: Provided is a pouch-type secondary battery including an electrode assembly, electrode tabs extending outward from the electrode assembly, a pouch-type battery case for housing the electrode assembly, first sealing portions for sealing the pouch-type battery case and the electrode tabs, and second sealing portions formed at positions with the exception of electrode tab-positioned sites between the first sealing portions and the electrode assembly. The secondary battery is configured to have a structure such that a channel is formed with electrode tab portions by further sealing inside portions of the electrode tabs with the exception of electrode tab-occupied portions. Such a structure allows for easy unidirectional discharge of gases even when the battery inside reaches a certain level of internal pressure due to evolution of gases and enables previous expectation of the gas discharge direction. Therefore, it is possible to provide a secondary battery with improved safety.

  • Patent number: 6838206
    Abstract: In a battery in which a separator is disposed between a cathode and an anode, a jelly roll is wound with the separator. The cathode, the anode and the separator are received in a battery case and surrounded with an electrolyte, and an opening of the battery case is sealed by a top cap assembly connected to the cathode. A curved groove is formed on the battery case as a safety element for preventing the explosion of the battery due to an increase of internal pressure, the groove being formed along a line of equal stress on the surface of the battery case.
