摘要： The present disclosure relates to an ion gel having superior ion conductivity and mechanical strength, a polymer electrolyte including the same, and a manufacturing method thereof. The method of manufacturing the ion gel is capable of simply and effectively manufacturing a polymer matrix through a one-pot reaction, thus exhibiting simple processing steps to thereby manifest excellent processing efficiency and generate economic benefits. Moreover, the polymer electrolyte including the ion gel can exhibit superior ion conductivity and mechanical strength despite the low glass transition temperature (Tg) of the monomer contained in the polymer matrix.

摘要： A battery case includes an upper plate portion and a lower plate portion that are spaced apart from each other in vertical direction to form an inner space therebetween. Battery cells are stacked in the inner space in the vertical direction and a pressing portion is disposed in a first space between the upper plate portion and an uppermost one of the battery cells. The pressing portion presses the stacked battery cells downwards from above due to gravity. A damping portion is disposed in a second space between the upper plate portion and the upper surface of the pressing portion. The upper end of the damping portion is supported by the upper plate portion and the lower end of the damping portion supports the pressing portion.

摘要： The present disclosure relates to garnet powder, a manufacturing method thereof, a solid electrolyte sheet using a hot press, and a manufacturing method thereof. In particular, the present disclosure provides a method for manufacturing Li7La3Zr2O12 (LLZ) garnet powder including preparing a mixture by first dry mixing Li2CO3, La2O3, ZrO2, and Al2O3. The mixture is first calcinated for 5 to 7 hours in a temperature range of 800 to 1000° C. The calcinated mixture is ground to a powder with an average particle size of 1 to 4 μm through dry grinding. A cubic-phased LLZ garnet powder is prepared by second calcinating the ground mixture for 10 to 30 hours in a temperature range of 1100 to 1300° C.
