Problems solved by technology

[0012] However, if a stacked electrode assembly is manufactured in this way, the electrodes and the separator need to be stacked one by one, so there is a problem that the time required for the work becomes longer and the productivity drops significantly.
Also, although the horizontal and vertical directions of the multilayer separator can be aligned, there is no material or jig for aligning the position of the electrodes mounted on the separator at an accurate position. neatly arranged and staggered problems
[0013] Furthermore, since the surfaces of the positive electrode and the negative electrode facing each other with the separator interposed therebetween are shifted, an electrochemical reaction does not occur in a part of the active material coated on the surface of the positive electrode and the negative electrode, thereby reducing the efficiency of the battery cell. The problem

Abstract

The present invention relates to a method for manufacturing an electrode assembly by a third process which is neither a stack folding process or a stack process. The method for manufacturing an electrode assembly in accordance with a preferred embodiment of the present invention comprises: a step (S10) of forming a unit structure comprising a structure stacked in the order of a first electrode, a first separation membrane, a second electrode, and a second separation membrane, or comprising a structure in which the structure is repeated multiple times; a step (S20) of forming an electrode assembly by stacking the unit structure in multiple layers; and a step (S30) of discharging a gas interposed between respective layers by pressurizing the electrode assembly.

Description

technical field [0001] The present invention relates to a method of manufacturing an electrode assembly by a third construction method of a stack-fold construction method or a non-stack construction method. Background technique [0002] Secondary battery Electric vehicle (EV), hybrid electric vehicle (HEV), plug-in hybrid electric vehicle proposed as a solution to the air pollution of existing gasoline vehicles and diesel vehicles using fossil fuels (PHEV) and other power sources are attracting attention, and large and medium-sized equipment such as automobiles require high output and large capacity, so large and medium-sized battery modules that electrically connect multiple battery cells are used. [0003] However, it is preferable that the large and medium-sized battery modules are made as small and light as possible, so that they can be stacked with a high degree of integration and are mainly used as large and medium-sized battery modules compared to square batteries and...
