Abstract: A hollow cathode system, a device and a method for the plasma-assisted treatment of substrates includes at least one hollow cathode, which can be connected to a power supply. The hollow cathode includes an electrically conducting main body with an opening which is bounded by ribs, follows a spiral or meandering path and allows a gas to pass through in a direction perpendicular to a surface of the main body. Connecting bridge elements are provided on the ribs. The bridge elements serve ensure mechanical stability of the hollow cathode and optimize potential distribution of the hollow cathode. With the hollow cathode system, high treatment rates are achieved for homogeneous treatment of substrates of a large surface area with high plasma stability.

Abstract: A crystalline, completely soluble lithium bis(oxalato)borate (LiBOB), to a method for producing the same and to the use of the lithium bis(oxalato)borate.
