Research Focus
Materials and architectures for energy conversion and storage; solid-state actuation; nanomaterials synthesis and reaction mechanism in batteries; energy storage device architecture design.

Research Summary

Professor Liu’s research focuses on designing materials and architectures for electrochemical energy conversion and storage applications. One area of interest is studying the mechanical behavior of rechargeable batteries in the context of optimization as either solid-state actuators or as long- life electrochemical energy storage devices. A second area is synthesizing nanostructured materials and probing the effect of composition and size on the thermodynamics and kinetics when they are used as battery materials. A third area is designing new architectures for energy storage devices with enhanced energy density while maintain long service life. Diverse approaches including new electrolyte development, interfacial structure design, and battery cell configuration engineering are employed.
