An apparatus for manufacturing an all-solid-state battery includes: a mold unit which includes a first hole extending vertically so as to have a shape and a width identical with a shape and a width of the all-solid-state battery, and a second hole extending horizontally so as to horizontally communicate with the first hole; a first pressing unit which includes a first protrusion member corresponding to the first hole, which is coupled with an upper part of the mold unit, and which presses downwards raw materials of the all-solid-state battery filling the first hole, and a second pressing unit which includes a second protrusion member corresponding to the first hole, which is coupled with a lower part of the mold unit, and which presses upwards the raw materials of the all-solid-state battery filling the first hole.

Apparatus for manufacturing all-solid-state battery comprising reference electrode and manufacturing method using same

A method of manufacturing a negative electrode for a secondary battery includes a first step of preparing a lithium metal sheet coated with a lithium metal or to which the lithium metal is adhered in a form of a thin film on a release film and wound into a roll, a second step of laminating the lithium metal sheet to allow the lithium metal to be adjacent to a negative electrode material mixture, to thereby manufacture a negative electrode in which lithium metal is laminated and a third step of applying pressure to the negative electrode. The release film is coated with silicon. The negative electrode manufacturing method uniformly laminates or bonds lithium metal which is difficult to handle on the negative electrode material mixture of the secondary battery and advantageously enhances the speed of the pre-lithiation by using the patterned lithium metal.
