Seminar Title: Using Nanoscale Structure to Improve Energy Materials – From Batteries to Conducting Polymers
Control of nanoscale structure is crucial for enhancing functionality in many emerging materials. This talk will begin with nanostructured battery materials that enable fast charging, and in the process, we will attempt to help refine our understanding of a phenomenon called pseudocapacitive charge storage. We will specifically examine how a combination of short ionic diffusion lengths in nanoporous electrode materials and a lack of first-order phase transitions can work together to reduce the diffusion constraints that limit charge/discharge speed. Next, we consider high-capacity anode materials that suffer from mechanical failure due to large volume changes. We will show how nanoporous architecture can stabilize these materials against capacity fade. Here, operando transmission X-ray microscopy (TXM) allows us to directly image volume change at the nanoscale during battery cycling,providing key…
