Summary:

For development of effective future electrochemical energy storage systems it is essential to understand the basic science associated with the gap between their theoretical energy content and their functional capacity. For electrochemical energy storage in inorganic ionic matrices, resistance to ion transport or electron transfer can manifest over multiple length scales, from the atomic/molecular scale to the crystallite/particle scale to the mesoscale. Complementary insights gained from ex situ, in situ, and operando spectroscopy, diffraction and electrochemistry studies of inorganic materials for energy storage will be highlighted, including materials which undergo both insertion and conversion processes.
