摘要： Provided is an electrode assembly manufacturing process comprising the following steps. First, wrapping a second separator around a laminate structure having alternating layers of positive electrodes, first separators, and negative electrodes. Second, simultaneously pressing the upper end and the lower end of the laminate structure including the second separator-3-2 to strengthen the adhesive strength between each layer of the laminate structure. Third, bonding the excess portions of the second separator-3-2 surrounding the structure, thereby adjusting to meet the standard requirements of the laminate structure. And fourth, bonding each of the bonded portions of the second separator to a respective adjacent portion of the second separator in the lateral dimension. The electrode assembly manufacturing process minimizes damage to the initial structure and allows the wrapping to suit the size of the structure, thereby increasing the utilization value of the electrode assembly.
