A method of manufacturing a cathode for an all-solid-state battery includes: stacking a protective member on a cathode current collector, the protective member including a protective layer and a mask layer disposed on the protective layer and having a central portion which is an empty space; coating the protective member with a cathode material so that the central portion of the protective member is filled with the cathode material; and removing the mask layer to form a cathode coating layer.

Cathode for all-solid-state battery for preventing short-circuiting between electrodes and method of manufacturing the same

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 LiLaZrO(LLZ) garnet powder including preparing a mixture by first dry mixing LiCO, LaO, ZrO, and AlO. The mixture is first calcinated for 5 to 7 hours in a temperature range of 800 to 1000&#xb0; C. The calcinated mixture is ground to a powder with an average particle size of 1 to 4 &#x3bc;m 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&#xb0; C.

Garnet powder, manufacturing method thereof, solid electrolyte sheet using hot press and manufacturing method thereof

Disclosed are a garnet-type solid electrolyte and a method for preparing the same. The garnet-based solid electrolyte of the present invention is prepared by adding AlOto a precursor containing hydroxide, thereby enhancing sintered density and ionic conductivity while having a pure cubic phase crystal structure without including impurities.
