Chemical transformations provide energy, fuel and chemicals for today’s society. Electrochemistry offers the possibility to drive chemical transformations under ambient temperature and ambient pressure. More importantly, the interconversion of chemical and electrical energy by electrochemical means (e.g., electrocatalysis) of using the electron potential to control the directions and rates of chemical processes provides a flexible and scalable solution to store energy in chemical bonds and retrieve this energy wherever and whenever needed. On the other hand, chemical transformation reactions have the potential to store more energy in rechargeable batteries than traditional intercalation reactions; examples include lithium sulfur, lithium air batteries. In this presentation, we will discuss our recent understanding and progress on materials electrochemistry of chemical transformation based energy storage/conversion and tool development for energy materials study. We will touch basic materials and reactions in Li-S batteries, environmental TEM study of catalytic materials and electrocatalyst investigation using earth abundant materials.
