The secondary battery realizes safety and further enhances energy density, cycle characteristics, and rate characteristics. The secondary battery can remarkably improve initial discharge capacity and capacity retention. A method for manufacturing the secondary battery is also disclosed. The method incudes preparing a negative electrode, interposing a separator between the negative electrode and a lithium metal plate to prepare a cell, electrochemically activating the cell to predope the negative electrode with lithium.

Abstract: A refrigerator having a carbonated water production module integrally provided with a carbon dioxide gas cylinder having carbon dioxide gas stored therein and a carbonated water tank to mix purified water with the carbon dioxide gas to produce carbonated water. The carbonated water production module is mounted to the rear surface of the door, and thus it may be cooled by cool air in the refrigeration compartment and be easy to access, and thereby repair and replacement thereof is facilitated. The dispenser includes a carbonated water discharge channel into which carbonated water from the carbonated water tank is discharged, and a purified water discharge channel into which purified water from the water tank is discharged. Since the purified water discharge channel does not pass through the carbonated water tank, a user is allowed to selectively dispense purified water or carbonated water anytime.

Abstract: A dishwasher including a washing chamber to wash dishes, a sump concavely formed at a lower portion of the washing chamber to collect water used in washing, a microfilter disposed at the sump to filter out dirt produced when the dishes are washed, and an ultrasonic generator to radiate ultrasonic waves toward the microfilter. Since the microfilter is automatically cleaned by the ultrasonic generator, a user may not need to manually clean the microfilter.
