Characterizing nanoscale energy carrier transport for renewable energy applications: lithium ion battery, microbial fuel cell, and thermoelectrics

 

  Renewable and clean energy generation and storage are one of society\'s greatest needs. In reality, many of renewable energy sources exist as different forms such as waste heat, sunlight, and wastewater, and thus require to develop a wide range of energy converting techniques. For example, solid-state thermoelectric modules can convert heat to electricity and bacteria in microbial fuel cells can directly convert chemical energy in organic matter to electricity while Li-ion batteries can reversely convert electricity to chemical energy. In particular, electrochemisty plays an important role in these techniques, such as batteries and microbial fuel cells. However, the complexity of electrochemically-driven reactions often made hard to improve the efficiency of these systems and warrants fundamental understanding. Here, we employ in-situ synchrotron-based spectro-microscopy to investigate the detailed kinetics and thermodynamics of electrochemical reactions while they take place. In this talk, I will present new insights on three important classes of renewable energy techniques : (1) lithium insertion in lithium iron phosphate olivine battery electrodes (2) single-bacterium level charge transfer in microbial fuel cell (3) electron and phonon transport in silicon thermoelectrics.
