摘要： Provided is a lithium secondary battery with enhanced energy density including a cathode using a cathode active material containing lithium mixed transition metal oxide absorbing and discharging lithium ions, wherein a final discharge voltage is in the range of about 1.5 V to about 2.75 V. A final discharge voltage can be reduced to 1.5 V to 2.75 V from 3.0 V by using various lithium mixed transition metal oxides as a cathode active material, or by using the various lithium mixed transition metal oxides with the LCO-based cathode material mixed. Compared to typical LCO-based cathode materials of which capacity and energy density do not change even if a final discharge voltage is decreased, a cathode material of the present invention results in further improving capacity by 10-20% as the final discharge voltage is decreased.

摘要： The present invention relates to a cap assembly and a battery including the same. More particularly, the present invention relates to a cap assembly for a cylindrical secondary battery, in which the support unit of a current interrupt device (CID) is seated in the inclined portion or the terraced portion of a gasket and thus the battery is dually sealed, thereby preventing the leakage of an electrolyte, and a cylindrical secondary battery including the cylindrical secondary battery. The cap assembly of the present invention is dually sealed for the leakage of an electrolyte. Accordingly, there is an advantage in that the safety of the battery can be greatly improved because the electrolyte is rarely leaked although the battery is shocked because of dropping.

摘要： A cap assembly of a cylindrical rechargeable battery includes an integrated gasket obtained by integrating a first gasket covering a top cap, a PTC element, and a safety vent and a second gasket covering a CID. The rechargeable battery including the cap assembly has the advantages of increasing a contact area between a safety vent and a gasket by integrating the existing dual-gasket structure to thereby increase a sealing effect, increasing a short circuit reactivity of the CID by freely changing the gasket structure according to the diameter of the current interrupting member to thereby improve stability, simplify components, and reduce a production unit cost.
