Abstract
A method for simultaneously forming alkali metal layers includes heating a laminate structure including a top layer, a bottom layer, and an alkali metal layer sandwiched between opposing facing surfaces of the top layer and the bottom layer. The laminate structure is heated to a peel temperature to at least partially melt the alkali metal layer and form a volume of molten alkali metal at the location of a peel site within the alkali metal layer. The top layer and the bottom layer apart from each other such that the alkali metal layer splits internally at the location of the peel site and is divided between the top layer and the bottom layer.
