Research Vision

Xu Lab lead research that fundamentally redefining our understanding of energy materials and driving innovation in new energy technologies. The lab also serves as a platform to transform how we educate the next generation of energy materials scientists by directly linking fundamental discoveries to educational programs—spanning K–12 outreach, undergraduate courses, and graduate training—and fostering the next generation of innovators.

Who we are

We are an interdisciplinary research team led by Professor Xin Xu at Arizona State University’s Polytechnic Campus. We bring together interests in materials science, chemistry, physics, and engineering, guided by curiosity and a shared commitment to discovery. Through hands-on research and collaborative learning, we help students develop independent ideas, experimental skills, and confidence in tackling challenging scientific questions.

What we do

Our research focuses on charge transport in ceramic and metallic materials for solid-state batteries, fuel cells, and next-generation energy technologies, using multimodal characterization to uncover how charge, structure, and extreme fields interact at material interfaces.
