Abstract
Abstract A battery, more specifically a battery cell for a lithium polymer battery, is made using a method that includes the lamination step of applying isostatic pressure to battery cell components. The method further includes the step of heating the components of the battery cell at least prior to the step of applying isostatic pressure. The components of the battery cell should also include a binder material that includes a polymer that softens when heated, thus allowing the components named above to laminate.
