Abstract (en)

[origin: DE19802839A1] A pattern is formed on a thin metal foil by filling a solution into apertures (2) in a mask film (1) of thickness corresponding to the height of solution to be introduced, followed by drying the solution and removing the mask film to leave a pattern of a dry substance. Independent claims are also included for the following: (i) a method of forming a cell with a non-aqueous electrolyte by carrying out the above process, using a solution of lithium ions in a n-methyl-2-pyrrolidone solvent and preferably a thin metal foil of aluminum or copper; (ii) apparatus for carrying out the above process; and (iii) a cell with a non-aqueous electrolyte, formed by the above process and method.
