Abstract: Provided are a vehicle sensor cleaning apparatus and a control method thereof. The vehicle sensor cleaning apparatus includes a liquid sprayer configured to spray washer fluid on at least one sensor arranged in a vehicle, an air sprayer configured to spray air on the at least one sensor, a liquid controller configured to control washer fluid spraying of the liquid sprayer, and an air controller configured to control air spraying of the air sprayer.

Abstract: An apparatus for controlling a discharge pressure of a fluid includes: a pump configured to suck the fluid through an inlet or to discharge the sucked fluid through an outlet; a distributor connected to the pump and to an injection nozzle provided by a sensor and configured to distribute the fluid discharged from the pump to the sensor; and a controller. The controller is configured to control the pump to operate selectively in accordance with detection of contamination of the sensor and to control operation of the distributor to be forcibly delayed during operation of the pump such that the fluid distributed to the sensor, when detected as being contaminated, is controlled to reach a selected required discharge pressure of different required discharge pressures selected in accordance with water amount information and a degree of contamination of the sensor.

Abstract: The present invention relates to a method for preparing a sulfide-based solid electrolyte, a sulfide-based solid electrolyte prepared by the method, and an all-solid-state lithium secondary battery including the sulfide-based solid electrolyte. The method of the present invention includes a) mixing Li2S with P2S5 to prepare a mixed powder, b) placing the mixed powder, an ether, and stirring balls in a container, sealing the container, followed by stirring to prepare a suspension, and c) stirring the suspension under high-temperature and high-pressure conditions to prepare sulfide-based solid particles.

Abstract: The present invention relates to an electrode and a secondary battery including the same, the electrode including an electrode active material layer, the electrode active material layer including an electrode active material and a conductive agent, the conductive agent including: a multi-walled carbon nanotube unit; and a carbon nanotube structure in which 2 to 5,000 single-walled carbon nanotube units are bonded to each other, wherein the carbon nanotube structure is contained in the electrode active material layer in an amount of 0.01 wt % to 0.5 wt %.

Abstract: A negative electrode includes a negative electrode active material layer, wherein the negative electrode active material layer includes a negative electrode active material and a conductive agent, wherein the negative electrode active material includes a silicon-based active material, the silicon-based active material includes SiOx(0?x<2), the conductive agent includes a carbon nanotube structure in which 2 to 5,000 single-walled carbon nanotube units are bonded side by side, and the carbon nanotube structure is included in an amount of 0.01 wt % to 1.0 wt % in the negative electrode active material layer. A secondary battery including the negative electrode, and a method of preparing same are also provided.

Abstract: A contamination control apparatus includes at least two pipes connected by a joint portion and configured to allow a processing fluid to flow therethrough, and a cover configured to enclose the joint portion and to provide an enclosed cavity between the cover and the joint portion. An inlet port is connected to the cover and configured to supply a gas to the cavity. An outlet port is connected to the cover and configured to exhaust the gas and a contaminant from the cavity.

Abstract: An apparatus for cleaning air, and a method for cleaning air using the apparatus, includes a housing including an air inlet through which air to be cleaned flows into the housing and an air outlet through which air that has been cleaned is exhausted from the housing, the housing isolating an interior thereof from external surroundings. A first filtering unit is disposed adjacent to the air inlet and includes a plurality of first filters for removing a first group of contaminants from the air to be cleaned. Each of the plurality of first filters is disposed substantially parallel to each other. A fan for drawing the air to be cleaned into the housing from the external surroundings is disposed in the housing.
