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： Disclosed are an all solid battery including a positive electrode layer including a positive electrode active material, a solid electrolyte and a conductive material coated with an insulator coating layer, an electrolyte layer, and a negative electrode layer and a method of manufacturing an all solid battery the same. In particular, the method includes: coating, by atomic layer deposition (ALD), a conductive material with an insulator by atomic layer deposition (ALD) to produce a conductive material surrounded by an insulator coating layer; producing a positive electrode layer including the conductive material coated with the insulator coating layer-formed conductive material, a positive electrode active material, and a solid electrolyte; and stacking and pressing the positive electrode layer produced above, an electrolyte layer and a negative electrode layer. The all solid battery can suppress side-reactions between the conductive material and the solid electrolyte, thereby advantageously maximizing energy density based on improved initial charge/discharge efficiency, and enhancing lifespan and power.

摘要： Disclosed is a side-assembly-type transmission mount, in which a powertrain-rotation-preventing unit is mounted to a case, which is coupled to the upper portion of a transmission bracket, thereby preventing a powertrain from falling when a bolt is fractured. The powertrain-rotation-preventing unit includes a rotation-preventing pipe configured to allow the bolt to be inserted therethrough and to have rotation-preventing protrusions protruding from the upper and lower portions thereof, first rotation-preventing recesses formed in a core so as to have shapes corresponding to the rotation-preventing protrusions on the rotation-preventing pipe, and second rotation-preventing recesses formed in a space formed in a transmission support bracket. The rotation-preventing protrusions on the rotation-preventing pipe are inserted into the first and second rotation-preventing recesses formed in the core and the transmission support bracket.
