Welcome to the Tang Lab at Drexel University!

The widespread transition from fossil fuels to renewable energy sources would have enormous environmental and economic benefits across the globe. By itself, the sun generates enough energy to power the world many times over. However, our current technology for storing this energy is inadequate. Developing efficient, scalable methods to store renewable energy is perhaps the greatest scientific and engineering challenge of the 21st century.

Electrochemistry yields direct, efficient transformations between electrical and chemical energy. By avoiding Carnot limitations, electrochemical systems can operate efficiently at ambient temperatures and pressures. Chemical bonds store far more energy than mechanical systems such as compressed air or pumped hydroelectricity, and the diversity of molecules that can be generated electrochemically promises tailored solutions for a given storage application. Electrochemical approaches are used in an incredible variety of systems, including batteries, fuel cells, supercapacitors,
and industrial synthesis.

Solutions for energy storage must have acceptable power, energy, lifetime, safety, and cost. Like the strands of a spiderweb, every aspect is necessary for the technology to succeed. Our research topics aim to improve these aspects from the device down to the nanoscale. We combine fundamental experimental and theoretical studies of chemical transport and kinetics with synthesis, characterization, and simulation of materials and architectures. The materials and methodologies developed by our lab strive to enable the rapid development and implementation of next-generation energy storage and conversion.
