| 20120021261 | ELECTROCHEMICAL CELL WITH A GAS PERMEABLE MEMBRANE - The present invention provides a means for minimizing and improving the reliability and safety of the electrochemical cells such as batteries, capacitors, or the like. The present invention involves forming one or more holes in an electrochemical cell such that the holes are connected to the outside, and attaching a gas permeable membrane around the hole such that the bonded surface of the gas permeable membrane is surface-treated in order to improve bonding properties. Thus, gas generated by the electrochemical cell is discharged to the outside to prevent the internal pressure of the electrochemical cell from rising, thereby reducing the weight and volume of the electrochemical cell and improving the reliability and safety thereof. | 01-26-2012 |
| 20110229753 | HIGH OUTPUT ELECTRICAL ENERGY STORAGE DEVICE - The present invention relates to an electric energy storage device such as a capacitor, a secondary battery, or the like, and more particularly, to an electric energy storage device capable of improving high output characteristics by using a voltage terminal. The electric energy storage device according to an exemplary embodiment of the present invention includes a positive electrode and a negative electrode storing electric energy and a positive current terminal and a negative current terminal connected to the positive electrode and the negative electrode to apply current; and a positive voltage terminal and a negative voltage terminal connected to the positive electrode and the negative electrode to detect voltage across the positive electrode and the negative electrode, wherein the charging or discharging operation is controlled by using the detected voltage across the positive electrode and the negative electrode as control voltage. | 09-22-2011 |
