    摘要: Provided are a method and system for rapidly cooling a lithium secondary battery. A conductive connector is connected to at least one of positive and negative electrode terminals of a lithium secondary battery, and the conductive connector is brought into contact with a coolant to cool battery cells. The coolant may be water or air and may flow a coolant tube formed of a synthetic resin. An end of the coolant tube is fixed to at least one of the positive and negative electrode terminals. Therefore, owing to a cooling means disposed at a side of the lithium secondary battery, the temperature of the lithium secondary battery can be prevented from increasing to a preset value due to abnormal heating, and thermal stability of the lithium secondary battery can be improved by rapid cooling.

    摘要: 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.

    摘要: A pouch type lithium secondary battery 100 including a medium- or large-sized battery module includes: a jelly-roll type electrode assembly; a resin-type first packing material 30 that is formed of a two-layer structure having an inner resin layer 30a and an outer resin layer 30b, and for packing the jelly-roll type electrode assembly in the form of a unit cell; and a metal-type second packing material 40 that integrally packs and contains two or more unit cells 20 packed in the first packing material 30 in the form of a module, and prevents moisture and gas penetration by a sealed structure. The pouch type lithium secondary battery 100 is applicable particularly to medium-and large-sized batteries for EVs, p-HEVs, HEVs, and so on.

    摘要: The present invention relates to a pouch type secondary cell with high water-resistance. The pouch type secondary cell comprises a positive electrode, a separation layer, and a negative electrode. Here, the sealing unit of the secondary cell includes steps so that the sealing unit has an outer side thinner than an inner side in thickness. The present invention is advantageous in that the manufacture process can be simplified, the water-resistance and sealing property of sealing portions can be further improved, and the manufacture costs can be reduced.

    摘要: Provided is a secondary battery including an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. The positive electrode includes a positive electrode non-coating portion that is not coated with an active material in a portion of a positive electrode collector. The negative electrode includes a negative electrode non-coating portion that is not coated with an active material in a portion of a negative electrode collector. The non-coating portions are disposed in at least one of upper and lower portions of the electrode assembly in a longitudinal direction of the electrodes. A positive electrode tab and a negative electrode tab are connected to the non-coating portions. The separator is a complex porous separator including a substrate coated with a binder polymer or an organic/inorganic mixture formed of a binder polymer and inorganic particles.
