NOVELTY - Manufacture of batteries for the production of cell preforms comprises pressing on two hot plates of a hot press at fixed temperature to form a cell preform from at least one set of laminated cell component. Prior to pressing, the laminated cell component along with an auxiliary layer is placed into the two hot plates of the press.    USE - For manufacturing lithium polymer secondary battery (claimed).    ADVANTAGE - Under proper pressure, temperature and press time, the method can rapidly make large-area cells with stable quality. The method achieves mass production of batteries with stable quality at low production costs. The longer-duration, lower stress pressing process is easily controlled to obtain the perfect adhesion between cell components (e.g., anode, separator, and cathode) and eliminate short. It increases yield rate. Single cell and cells in series and in parallel can be formed by designed combination, and thus reduce the time required for manufacture. Pressing method can press the battery with multi-layer and multi-opening in one time by the multi-opening hot press, which will achieve mass production, extensive increase in production efficiency, and reduction of investment in equipment. The use of the press with large area can produce a single large-area cell (in series and/or parallel). The area of the cell is determined by the size of the press, such as 8.5x11 i nches for electrical mobiles. After pressing, the cells can be cut into desirable size to make smaller batteries (suitable for cellular phones or palm-size computer), thus the size and shape of the produced battery are extremely flexible. During pressing, the temperature and stress of the pressed materials are constant and stable and extensively improve the stability and yield of the production, either for the pressing of single cells or the multi-layers/multi-opening mass pressing.    DETAILED DESCRIPTION - Manufacture of batteries for the production of cell preforms, which are then activated into cells comprises:    (a) stacking layers of components into at least one set of laminated cell component;    (b) adding an auxiliary layers onto the first and second sides of each laminated cell component;    (c) fixing the temperature of at least two hot plates of a hot press;    (d) placing at least one set of laminated cell component along with an auxiliary layer into the two hot plates of the hot press;    (e) pressing on the two hot plates at the fixed temperature to form a cell preform from the set of laminated cell component;    (f) activating the cell preform into a cell; and    (g) packaging the cells into a battery.    An INDEPENDENT CLAIM is also included for a separator for insulating the anode and cathode in a cell comprising a woven glass fabric, where two surfaces of which are coated with silicone.
