摘要： A method of manufacturing an all-solid-state battery electrode, an all-solid-state battery electrode manufactured by the method, and an all-solid-state battery including the electrode are disclosed. In the method, a specific type of binder included in the electrode is prepared in a fiber form by applying pressure to the binder under specific conditions, so that the fiber-form binder thus prepared has an average fineness that satisfies a specific range. Therefore, the all-solid-state battery including the electrode has an advantage of having high capacity even in the case of electrode thickening for high loading.

摘要： An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.

摘要： A cooling method can be used with an electric vehicle that comprises a vehicle charging connection unit connected to an external cable connected to a charger located outside the electric vehicle, a battery configured to be charged through the vehicle charging connection unit, and a pump configured to circulate cooling water to cool the vehicle charging connection unit. The cooling method includes determining whether an amount of cooling water is insufficient and, upon determining that the amount of cooling water is insufficient, restricting a charging rate of charging power supplied through the vehicle charging connection unit.

摘要： An eco-friendly vehicle and a transmission hydraulic pressure control method for the same are provided. The vehicle includes an oil pump that estimates an inner temperature without using a temperature sensor. The method includes determining a driver request output and determining a required hydraulic pressure corresponding to the request output. A temperature of an oil pump unit is estimated to operate an electric oil pump to supply a hydraulic pressure to a transmission, based on the required hydraulic pressure and driving status information. An output torque is then adjusted based on the estimated temperature.

摘要： A cooperative control method and apparatus for maintaining driving in response to engine clutch failure are provided. The cooperative control method includes monitoring refill temperature conditions of operating oil of an engine clutch and performing cooperative control between a radiator and an engine cooling water circulation pump based on change in temperature of the operating oil of the engine clutch. Additionally, the method includes determining whether the engine clutch is in a refill dangerous stage and turning off an engine to be turned off when the engine clutch is in the refill dangerous stage. Whether the temperature of the operating oil is mitigated is determined based on the refill temperature conditions, when the engine is turned off and oil refilling is performed when the temperature of the operating oil is not mitigated.

摘要： Disclosed is a method of manufacturing an all-solid state battery. The method includes coating a first slurry or composition having on a substrate to form a first electrolyte layer a predetermined thickness, coating a second slurry or composition on the first electrolyte layer to form a second electrolyte layer having a predetermined thickness, laminating an electrode layer on the second electrolyte layer, bonding the electrode layer to the second electrolyte layer through pressing, and removing the substrate from the first electrolyte layer. The first slurry or composition of the first electrolyte layer has content of a binder less than that of the second slurry or composition of the second electrolyte layer, and thus, the substrate may be easily removed from the first electrolyte layer.
