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.

Abstract: A method for coating a web with a metal layer includes heating a metal in a container to create molten metal. The metal is selected from a group consisting of lithium (Li), sodium (Na), potassium (K), indium (In), tin (Sn), cadmium (Cd), zinc (Zn), and lead (Pb). The method includes coating at least one surface of a web with a metal layer using the molten metal. The web is made of a material selected from a group consisting of copper (Cu), nickel (Ni), titanium (Ti), stainless steel, polymer, and carbon.

Abstract: A method for fabricating an electrode for a battery cell includes supplying a first electrode film from a first roll. The first electrode film comprises an active material for exchanging lithium ions and a binder. The method includes treating a first side of the first electrode film using a first plasma treatment system; supplying a current collector, and heating and pressing the first side of the first electrode film to a first side of the current collector together using first and second rollers.
