Energy Storage and Electrochemistry Lab

Welcome to Energy Storage and Electrochemistry Lab 

About us

Electrochemistry is a branch of chemistry concerned with the interrelation of electrical and chemical effects. Our research focuses on the reactions resulting from the transport of charge carriers (electrons or ions) across the material interfaces in electrochemical systems. Recently, with the increasing demand for energy and intermittent features of sustainable energy systems, e.g., solar and wind power, energy storage via electrochemical reactions has attracted a lot of attention.

 Research at the ESE laboratory aims at applying fundamental electrochemical understanding gained from laboratory-scale study, combining with diverse material analyses, to develop high-performance energy-storage devices, such as lithium-ion batteries, sodium-ion batteries, solid-state batteries, supercapacitors, etc. Also, the synthesis techniques, cell assembling skills, and material characterizations are emphasized in the scope of our study. We also pursue the utilization of ionic liquid as battery/supercapacitor electrolytes, aiming to achieve high safety and high cycling stability. To dive deep into the energy-storage mechanism National Synchrotron Radiation Research facility (In-situ XRD, XAS, etc.) is employed to examine the electrochemical reactions between the electrodes and electrolytes.

 Besides academic performance, Chang’s group has strong bonding with industries and has devoted much effort to practical complications. Our research programs are funded by the National Science and Technology Council (NSTC), Ministry of Education, China Steel Corporation, Industrial Technology Research Institute (ITRI), National Chung-Shan Institute of Science and Technology (NCSIST), and several private energy-related firms.
