Abstract |
The function of most energy devices such as lithium ion battery (LIB), metal-air battery, fuel cell and DSSC is based on the electrochemical redox reactions of electrode materials, which is accompanied by phase transition of electrode materials or catalytic reactions on the surface of electrode materials. Compared to the importance of phase transition on LIB between lithiated and delithiated phases, catalytic redox reactions play a very important role on metal-air battery and fuel cell devices because catalytic oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are involved in those devices. In addition, hydrogen evolution reaction (HER) and I3-/I- redox coupled reaction are key issues on hydrogen-based fuel cell and DSSC devices.
Here, we would like to introduce the theoretical overpotential calculated by applying standard density functional theory in combination with the computational standard hydrogen electrode (SHE) model to HER/OER/ORR and IRR of energy storage and harvesting devices.
