Two-stage lamination process |
摘要 |
Blisters or air bubbles between battery layers can be a problem with the lamination of battery layers. The blistering can be reduced by a two-step pressure-applying method. In the first step, a relatively small first pressure is applied to the battery layers. The relatively small first pressure is done such that air bubbles between the battery layers are not formed. Next, a second larger pressure is applied to the battery layers to laminate the battery layers together. In an alternate embodiment, the pressure applied to the battery layers is changed from a low pressure to laminating pressures in one step.
