摘要： Disclosed is a lithium secondary battery comprising a cathode (C), an anode (A), a separator and an electrolyte, wherein the battery has a weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode of between 0.44 and 0.70, and shows a charge cut-off voltage of between 4.35V and 4.6V. The high-voltage lithium secondary battery satisfies capacity balance by controlling the weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode. Therefore, it is possible to significantly increase the available capacity and average discharge voltage of a battery using a lithium/cobalt-based cathode active material, which shows an available capacity of about 50% in a conventional 4.2V-battery. Additionally, it is possible to significantly improve battery safety under overcharge conditions, and thus to provide a high-voltage and high-capacity lithium secondary battery having excellent safety and long service life.

The sliding means including a rotatable lever, a lower clamp operative in conjunction with the rotatable lever, and a pad on which the side rail sits. The side rails disposed at the left side and right side of the roof panel of a vehicle have different bottom surfaces. Moreover, the pads of the sliding means, which directly contact the bottom surfaces of the side rails, have different sitting surfaces in order to tightly contact with the side rails. Accordingly, it is possible to effectively prevent the crossbar from being installed to the side rails in a reverse direction.
