Electrochemical Properties and Valence Tuning of Li-Metal-Nitrides — •Elisa Thauer¹, Michael Richter¹, Alexander Ottmann¹, Christoph Neef¹, Manuel Fix², Anton Jesche², and Rüdiger Klingeler¹ — ¹Kirchhoff Institute for Physics, Heidelberg University, D-69120 Heidelberg, Germany. — ²Experimentalphysik VI, Institut für Physik, Universität Augsburg, D-86135 Augsburg, Germany.

Lithium nitrides Li₂(Li_1−xM_x)N with M = Fe or Ni are studied regarding their potential as anode materials in lithium-ion batteries by means of cyclic voltammetry and galvanostatic cycling. In addition, based on these results, the lithium content and thus the valence of the metal ions is altered electrochemically and the effect on the magnetic properties is studied by means of SQUID magnetometry.
