| 520 | _ | _ | |a Electrode materials for batteries and electrolysers are optimized and analyzed regarding their application, which has led to modern high-performance materials. Until now, it is spectroscopically challenging to observe the intrinsic chemical equilibria between electrode material and electrolyte that may influence more than just the interface. Monitoring changes in the bulk electrode material without external potential would contribute to the understanding of the overall system.Here we use lithium titanate as inorganic material [1-2] and a nitrogen containing organic carbon material to show how the pure contact of the electrolyte influences the electronic structure/dynamics of such solid materials. In case of the Lithium titanate an electrolyte dependent change of the bulk could be detected by NMR (Nuclear Magnetic Resonance), which allows e.g. conclusions on the two-phase equilibrium of lithium ions. In the case of the diamagnetic carbon material, radical centres could reversibly be induced and observed by EPR (Electron Paramagnetic Resonance), supporting an electrolyte dependent reactivity in catalytic applications. Overall, the observations allow aspects of the intrinsic activity of the materials to be better understood and thus indicate additional starting points for improving the electrochemical systems.
