Abstract: The present disclosure relates to an electrode stack for a lithium secondary battery, in which one or more positive electrodes and one or more negative electrodes are alternatingly stacked with a separator therebetween and insulation layers are formed on the outermost positive electrodes of the electrode stack. The insulation layers have an average thickness of 1 ?m to 8 ?m. The positive electrodes include a positive electrode collector; a positive electrode active material layer; and a protective layer including an inorganic compound. The protective layer is disposed between the positive electrode collector and the positive electrode active material layer. Additionally, an electrode assembly and a lithium secondary battery which include the electrode stack are also disclosed.

Abstract: A fuel system is disclosed which is adapted to improve engine ignition properties by ensuring that, when the engine ignition is turned off, residual fuel left over in the engine area after use is not returned to the fuel tank but instead remains in a common rail injector area.

Abstract: Disclosed is a structure for preventing the heat of a muffler from being diffused, which prevents the heat generated by the muffler from being diffused into the peripheral components in the engine room and discharges the heat through the engine hood to the outside. The structure for preventing the heat of the muffler for a construction machine includes a plurality of frames mounted on the bottom of the engine room outside the muffler, a shield supported by the frames so as to surround the outside of the muffler to form a shielding area, and a detachment means formed on one side of the shield.

Abstract: Heavy equipment having a tool box opening in forward direction of the equipment is provided, in which a tool box door mounted on an upper frame of an excavator can be simply opened and closed through pressing of a button, an auxiliary structure, such as a handrail that is used when an operator ascent toward an engine room, is not required, and the shape of the tool box door can be freely designed to sufficiently secure storage space.

Abstract: Construction equipment having a side mirror fixing means is provided, in which a ball of a ball joint for rotatably fixing a side mirror to a structure of the equipment and its supporting parts are mounted on the outside of the side mirror, so that an operator can confirm with the naked eye and manage on the occurrence of release or gap of a fastening bolt.
