If studying materials for electrochemical applications, similar opportunities and limitations exist as for other materials. However, some established paradigms for data analysis and interpretation need to be questioned for ion-conducting materials with stochastic occupancy. Since performance-limiting processes often occur at interfaces, one would like to study working cells, ideally during operation. In this case various additional challenges are introduced, such as electrically conducting components that cause losses in common MR setups, or changing impedances during cycling and aging that alter the Q of the resonator.In this talk, strategies will be discussed to identify and mitigate some of these challenges. For some questions, a compromise is offered by studying components of electrochemical systems, where interfaces are present yet losses can be minimised. NMR and EPR examples of battery applications will be presented where sample preparation and protocols are adapted to address specific questions. Laplace inversion without non-negativity constraint is demonstrated as a useful tool to analyse relaxation and diffusion data, and the importance of an integrated approach combining MR and theory for data interpretation is highlighted. 001037565 536__ $$0G:(DE-HGF)POF4-1223$$a1223 - Batteries in Application (POF4-122)$$cPOF4-122$$fPOF IV$$x0 001037565 536__ $$0G:(GEPRIS)422726248$$aDFG project G:(GEPRIS)422726248 - SPP 2248: Polymer-basierte Batterien (422726248)$$c422726248$$x1 001037565 536__ $$0G:(BMBF)13XP0352B$$aInOPlaBat - In-Situ und Operando Plating Detektion in Batterien (13XP0352B)$$c13XP0352B$$x2 001037565 909CO $$ooai:juser.fz-juelich.de:1037565$$pVDB 001037565 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162401$$aForschungszentrum Jülich$$b0$$kFZJ 001037565 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-Juel1)162401$$aRWTH Aachen$$b0$$kRWTH 001037565 9131_ $$0G:(DE-HGF)POF4-122$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1223$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vElektrochemische Energiespeicherung$$x0 001037565 9141_ $$y2025 001037565 920__ $$lyes 001037565 9201_ $$0I:(DE-Juel1)IET-1-20110218$$kIET-1$$lGrundlagen der Elektrochemie$$x0 001037565 980__ $$atalk 001037565 980__ $$aVDB 001037565 980__ $$aI:(DE-Juel1)IET-1-20110218 001037565 980__ $$aUNRESTRICTED
