| 20090176153 | THREE-DIMENSIONAL ELECTRODE TERMINAL FOR POUCH-TYPED BATTERY - Disclosed herein is a three-dimensional electrode terminal of a battery having an electrode assembly mounted in a pouch-shaped case, wherein a part of the electrode terminal, which is exposed from the battery case, has a predetermined thickness, and has a perpendicular surface (a perpendicular end surface) formed on the end thereof. According to the present invention, it is possible to easily accomplish the connection between the electrode terminal and the electrically connecting member without modifying the shape of the electrode terminal, and it is possible to easily accomplish the connection for detecting the voltage, the current, and the temperature of the battery. Furthermore, the mechanical strength of the three-dimensional electrode terminal according to the present invention is higher than that of the conventional plate-shaped electrode terminal. Consequently, the stability of the three-dimensional electrode terminal is high in the state that the electrode terminal is electrically connected with the electrically connecting member, and the electrical connection is easily accomplished even in a small space, especially when batteries are stacked one on another with high density so as to manufacture a medium- or large-sized battery module. | 07-09-2009 |
| 20090211082 | SECONDARY BATTERY FOR MEDIUM AND LARGE SIZE BATTERY MODULE - Disclosed herein is a secondary battery for medium-sized or large-sized battery modules. The secondary battery is assembled while an electrically connecting member used at the time of manufacturing a battery module is previously welded to at least one of electrode terminals of the secondary battery. | 08-27-2009 |
| 20090305126 | SECONDARY BATTERY HAVING ELECTRODE WITH SELF CUTTING PART TO BE DESTRUCTED ON APPLICATION OF OVER-CURRENT - Disclosed herein is a plate-shaped secondary battery used as a unit cell for middle- or large-sized battery pack, the secondary battery having an electrode assembly, which can be charged and discharged, mounted in a sheet-shaped battery case including a metal layer and a resin layer in a sealed state, the electrode assembly having electrode terminals protruding outside a sealing part of the battery case, wherein at least one of the electrode terminals is provided at a position spaced a predetermined distance from the sealing part with a self cutting part having a vertical sectional area less than that of the remaining part of the at least one electrode terminal such that the self cutting part can break first when overcurrent flows in the secondary battery. | 12-10-2009 |
| 20100021821 | Secondary Battery Having Electrode for Improvement of Stability During Overcharge - Disclosed herein is a secondary battery including an electrode assembly that can be charged and discharged, wherein the electrode assembly includes an electrode (‘safety electrode’) composed of a material that effects an electrochemical reaction when the secondary battery is overcharged (Overcharge reaction material’). The safety electrode according to the present invention is not directly added to components related to the operation of the secondary battery. Consequently, the safety electrode does not deteriorate the performance of the battery during the normal operation of the battery, and the safety electrode consumes the overcharge current through the electrochemical reaction, when the battery is overcharged, whereby the safety of the battery is fundamentally secured. | 01-28-2010 |
| 20100055575 | LITHIUM SECONDARY BATTERY OF ELECTROLYTE CONTAINING AMMONIUM COMPOUNDS - Disclosed is a lithium secondary battery using a cathode containing a lithium-containing transition metal oxide and an anode containing graphitized carbon, characterized in that an ammonium compound capable of providing ammonium ions is added to a non-aqueous electrolyte. Therefore, the present invention provides a lithium secondary battery having improved high-temperature performance by reducing decreases of residual capacity and recovery capacity resulting from high-temperature storage of the battery, via addition of such an ammonium compound. | 03-04-2010 |
| 20100190081 | STACKING-TYPED SECONDARY BATTERY PROVIDING TWO OR MORE OPERATION VOLTAGES - Provided is a stacked-type secondary battery comprising a battery cell formed by stacking a plurality of full cells having a structure of cathode/separator/anode or bicells having a structure of cathode(anode)/separator/anode(cathode)/separator/cathode(anode), as a unit electrode assembly, wherein a cathode active material and/or an anode active material in two or more unit electrode assemblies are configured to have a different composition to induce a voltage difference and separate electrode terminals are installed in a battery case according to the voltage difference to thereby simultaneously provide two or more voltages by a single battery. | 07-29-2010 |
| 20100209781 | LITHIUM SECONDARY BATTERY OF IMPROVED HIGH-TEMPERATURE CYCLE LIFE CHARACTERISTICS - Disclosed is a lithium secondary battery comprising a cathode including a lithium-containing transition metal oxide, an anode including a carbon-based material, and a non-aqueous electrolyte with addition of a compound of formula (1). Incorporation of the compound (1) into the electrolyte significantly improves the high-temperature performance and cycle life characteristics of the battery. | 08-19-2010 |
| 20110165472 | LITHIUM SECONDARY BATTERY OF IMPROVED HIGH-TEMPERATURE CYCLE LIFE CHARACTERISTICS - Disclosed is a lithium secondary battery comprising a cathode including a lithium-containing transition metal oxide, an anode including a carbon-based material, and a non-aqueous electrolyte with addition of a compound of formula (1). Incorporation of the compound (1) into the electrolyte significantly improves the high-temperature performance and cycle life characteristics of the battery. | 07-07-2011 |
