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.

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： An all-solid-state battery having an increased lifespan is equipped with a pressure pad layer. More particularly, the all-solid-state battery includes a unit cell and a pressuring pad layer. The unit cell is composed of a cathode, an anode, and a solid electrolyte layer positioned between the cathode and the anode. The pressurizing pad layer is positioned on each side of the unit cell and includes a non-porous upper layer, a non-porous lower layer, and a porous core layer positioned between the non-porous upper layer and the non-porous lower layer.
