Abstract: The thickness of a terminal connection portion of a positive electrode current collector is greater than that of a terminal connection portion of a negative electrode current collector. The terminal connection portion of the positive electrode current collector has a through-hole, and a positive electrode terminal is inserted into the through-hole and is upset on the terminal connection portion. The terminal connection portion of the negative electrode current collector has a through-hole, and a negative electrode terminal is inserted into the through-hole and is upset on the terminal connection portion. A recessed portion is formed in a lower surface of the positive electrode terminal connection portion around the through-hole, and a lower end portion of the positive electrode terminal is disposed in the recessed portion.

Abstract: A core prevents a battery separator wound therearound from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.

Abstract: Disclosed is a nanotubular intermetallic compound catalyst for a positive electrode of a lithium air battery and a method of preparing the same. In particular, a porous nanotubular intermetallic compound is simply prepared using electrospinning in which a dual nozzle is used, and, by using the same as a catalyst, a lithium air battery having enhanced discharge capacity, charge/discharge efficiency and lifespan is provided.

Abstract: A method for adjusting an output of a fuel cell system is capable of estimating a dry state of a fuel cell vehicle by comparing air flow rates, and adjusting a maximum output applicable to the fuel cell vehicle, thus enabling the fuel cell vehicle to be stably driven. The method for adjusting the output of the fuel cell system includes comparing an air flow rate required for driving and an actually introduced air flow rate to calculate an average air flow rate, and calculating an available output of the vehicle using preset mapping data with respect to the average air flow rate.

Abstract: A molten salt battery includes an electrode group which includes a first electrode, a second electrode, and a separator electrically insulating the first electrode and the second electrode; a molten salt electrolyte; a bottomed case which houses the electrode group and the molten salt electrolyte, the bottomed case having an opening; a cover plate which seals the opening of the case; a first external terminal of the first electrode and a second external terminal of the second electrode which are provided on the cover plate; a bus bar component fixed to the first external terminal; a first insulating part which is interposed between the first external terminal and the bus bar component so as to electrically insulate the bus bar component and the first external terminal; a thermal fuse component which is electrically connected to the bus bar component and the first external terminal and provides electrical continuity between the bus bar component and the first external terminal when the ambient temperature is l

Abstract: A method and apparatus for treating wastes by gasification recovers useful resources including energy, valuables such as metals, and gases for use as synthesis gas for chemical industries or fuel. The wastes are gasified in a fluidized-bed reactor at a relatively low temperature. Gaseous material and char produced in the fluidized-bed reactor are introduced into a high-temperature combustor, and low calorific gas or medium calorific gas is produced in the high-temperature combustor at a relatively high temperature. The fluidized-bed reactor preferably is a revolving flow-type fluidized-bed reactor. The high-temperature combustor preferably is a swirling-type high-temperature combustor.
