Our advances in cryogenic electron microscopy have enabled us to image highly beam-sensitive materials at unprecedented resolution. For batteries involving liquid electrolytes, for example, the ability to structurally and chemically characterize buried liquid-solid interfaces have provided new insight into the underlying processes that dictate the performance and durability of a battery. In Fuel cells it is the soft polymer electrolyte and interfaces between soft ionomers and solid catalysts that are critical. Our work demonstrates the impact novel characterization methods can have on our understanding of energy storage and conversion system.
