      abstract     = {Electron Paramagentic resonance (EPR) spectroscopy is a
                      sensitive tool to probe structural and electronic properties
                      of paramagnetic centers. Focusing on the study of
                      Lithium-ion batteries, this involves the monitoring of
                      changes in oxidation states of transition-metal ions upon
                      Lithium (de)intercalation, as well as the anti-site
                      diffusion of these centers as a function of extended cycling
                      and the formation of radical centers in the
                      solid-electrolyte interphase layer. In the case of metal-air
                      batteries, also the oxygen reduction / evolution catalyst
                      can be monitored during operation. The information obtained,
                      typically extends over the complete volume of a sample. In
                      certain cases, however, also interphase-sensitive
                      experiments can be performed. Temperature-dependent EPR
                      experiments typically allow to asses also dynamic
                      properties, by exploiting the variation of the EPR
                      susceptibility that can be used to estimate activation
                      barriers for ionic motion. Information on electronic
                      conductivities can be gathered by analyzing anisotropic
                      line-shape functions, such as the Dysonian line shape for
                      instance. References [1] P. Jakes, G. Cohn, Y. Ein-Eli, F.
