Towards optimized preparation of cathode materials: How can modeling and concepts be used in practice

A typical state-of-the-art Li cathode is a composite material consisting of many (nano) phases so its overall kinetics can be extremely sophisticated. In this paper we first show how one can identify selected important kinetic steps that may crucially affect the overall electrode performance. Based on relatively simple concepts supported with selected model experiments, we also give several practical recipes that might be helpful for designing of cathodes with improved overall kinetics.
