"The development of innovative technologies often requires fundamental new materials properties of individual components. In the present work, metastable metal fibers with unique mechanical and thermodynamic properties as well as crystallographic characteristics were linked to form mechanically stable, elastic 3-dimensional networks without changing the geometry, physical and thermodynamic properties of the fibers. The metal fiber networks have been used in lithium-ion battery technology as 3-dimensional current collectors, fundamentally improving battery technology. Worldwide there is an urgent need for improved battery technologies which are more ecological and economical. \r\nThe metal fibers produced by a Melt spinning process are based on a copper silicon alloy. The basic physical and thermodynamic properties as well as the crystallographic state of the metal fibers were first quantified. The metal fibers had a length of several centimeters, a width of 10-100 micrometers, and a thickness of 2-10 micrometers. The mechanical properties were quantified as a function of metal fiber dimension, crystallographic and thermodynamic state. In particular, the thermodynamic metastable phase was shown to be instrumental for linking the metal fibers. During the metal fiber fabrication process, the molten metal is cooled and solidified within a few milliseconds. As a result, the crystalline structure at room temperature is not in a thermodynamic equilibrium, the stored energy of which was determined. \r\nA permanent linkage of the metal fibers was successfully implemented by cold and warm sintering of the fibers without affecting the basic geometry and partly the physical as well as thermodynamic properties of the fibers. Low activation of atomic diffusion by means of mechanically built-up pressure or temperature resulted in a linkage preferentially at the contact points between fibers. The reason for this is the crystallographic energy stored in the fibers during quenching of the molten metal. \r\nThe 3-dimensional metal fiber networks were investigated in terms of their suitability as electrical current conductors in lithium-ion batteries. In particular, this work focused on improving the mechanical and electrical properties of lithium-ion batteries, which are the basis for a variety of processes in batteries. In principle, the 3-dimensional metal fiber networks enabled the fabrication of functional super-thick battery electrodes, which have a significantly increased surface capacitance of greater than 8 mAh cm-1."^^ .
