摘要： An electrical energy power source comprises a casing made by micro-bonding an upper ceramic wafer and a lower ceramic wafer to the opposed surfaces of a ceramic ring. The upper and lower ceramic wafers have respective first and second conductive pathways extends therethrough. A first current collector supporting a first active material layer contacts the upper ceramic wafer and the first conductive pathway, and a second current collector supporting a second, opposite polarity active material layer contacts the lower ceramic wafer and the second conductive pathway. A separator resides between the first and second active materials, and an electrolyte filled into the casing through a fill port activates the active materials. The first and second conductive pathways serve as opposite polarity terminals for the power source.

摘要： The present disclosure relates to a method for manufacturing a secondary battery including a gel polymer electrolyte and a secondary battery obtained thereby. The method can inhibit thermal crosslinking of a gel polymer electrolyte during the wetting with an electrolyte, and facilitate thermal crosslinking after the wetting with an electrolyte is finished. In addition, the method can increase uniformity of thermal crosslinking by controlling the oxygen content in a cell.
