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 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: An eddy current non-destructive evaluation system for an electrode film material includes: at least one control module configured to generate a transmission signal; and a first pair of coils. The first pair of coils includes: a first coil disposed adjacent the electrode film material and configured to operate in a transmit mode, and, based on the transmission signal, to generate an electromagnetic field that passes through the electrode film material; and a second coil disposed adjacent and on an opposite side of the electrode film material as the first coil and configured to operate in a receive mode. The second coil is configured to generate a electromagnetic field voltage based on the electromagnetic field. The at least one control module is configured, based on the electromagnetic field voltage, to at least one of determine a thickness of the electrode film material and detect a defect of the electrode film material.
