A method for pre-treating lithium metal for a lithium secondary battery including stripping a surface oxide film formed on a surface of the lithium metal by discharging the battery, and a plating lithium metal on the surface of the lithium metal, from which the surface oxide film has been stripped, by charging the battery.

In a method and a device for electrolytically polishing inner surfaces of a recess in a workpiece made of metal, in particular a workpiece printed in three dimensions, provision is made that a cathode is introduced into the recess and polishes the inner surface of the recess using an electrolyte having a slow diffusion rate.
