Abstract:
A method of manufacturing batteries for the production of cell preforms and then activating the preforms into cells, comprising the steps of:stacking layers of components into at least one set of laminated cell components; adding an auxiliary layer onto a first and second sides of each of said laminated cell component; fixing the temperature of at least two hot plates of a hot press; placing at least one set of said laminated cell components along with said auxiliary layers into at least one opening in which an opening is defined by said two hot plates of said hot press; pressing at least one set of said laminated cell components along with said auxiliary layers in at least one opening at said fixed temperature in order to form a cell preform from at least one set of said laminated cell component; activating said cell preform into a cell; and packaging said cells into a battery, wherein said auxiliary layers include one or more of each of a buffer, a release film and a thermally-conductive separating plate.
