ELECTRODE ASSEMBLY MANUFACTURING METHOD INCLUDING SEPARATOR CUTTING PROCESS |
摘要 |
Provided is an electrode assembly manufacturing method including a process of cutting a separator included in an electrode assembly to have a margin protruding from an electrode plate. The method includes a first process of manufacturing one type of basic unit sheets having a structure in which electrode materials and separator materials, which are the same in number, are alternately stacked, or two or more types of basic unit sheets having a structure in which electrode materials and separator materials, which are the same in number, are alternately stacked, and a second-A process of cutting a portion of a margin area of the separator materials, which are not covered with the electrode materials, such that the separator materials of the basic unit sheets protrude over a specific distance from edges of the electrode materials. |

1. An electrode assembly manufacturing method comprising:
a first process of manufacturing one type of basic unit sheets having a structure in which electrode materials and separator materials, which are the same in number, are alternately stacked, or two or more types of basic unit sheets having a structure in which electrode materials and separator materials, which are the same in number, are alternately stacked; and a second-A process of cutting a portion of a margin area of the separator materials, which are not covered with the electrode materials, such that the separator materials of the basic unit sheets protrude over a specific distance from edges of the electrode materials, wherein the one type of the basic unit sheets have a four-layer structure formed by sequentially stacking a first electrode material, a first separator material, a second electrode material, and a second separator material, or a structure formed by repeatedly stacking the four-layer structure, and the two or more types of the basic unit sheets are stacked one by one in a predetermined order to form the four-layer structure or a structure formed by repeatedly stacking the four-layer structure. |
