Professor Chunyu Zhu's research lab specializes in the design and synthesis of advanced functional materials, particularly biomass-derived carbon and metal oxide nanostructures, for sustainable energy storage and conversion applications. The lab focuses on developing green, scalable synthetic methods to create hierarchical porous carbons, nanostructured anodes and cathodes for lithium-ion and other rechargeable batteries, as well as thermally conductive and shape-stabilized phase change materials for thermal management. A key research direction involves using natural templates and sustainable precursors—such as starch, calcium carbonate, and magnesium compounds—to engineer materials with controlled porosity, morphology, and enhanced electrochemical performance. The lab also investigates dendrite suppression in zinc-based batteries through tailored hydrogel electrolytes, advancing the safety and efficiency of next-generation aqueous batteries.

The development of green and clean synthetic techniques to produce carbon materials for energy storage and conversion applications has motivated researchers to use sustainable biomass. In this study, hierarchical porous carbon (HPC) with very high specific surface area and controlled porosity is synthesized by a novel and facile method, which employs an exothermic pyrolysis process of starch–magnesium nitrate raw materials with subsequent high temperature thermal treatment and acid washing. The
This paper presents a biomass-derived porous carbon containing macro/mesopores for high-performance LIB anodes.
Anisotropic thermally conductive and shape-stabilized phase change composites were prepared with vertically aligned carbon fibers as supporting scaffolds.
This paper presents a new CaCO3-template synthesis of highly nanoporous manganese oxide hollow structures and their transformation to high-performance LiMn2O4 cathodes for lithium-ion batteries via the facile coprecipitation of Mn–Ca-carbonates and temperature-controlled decomposition of MnCO3 and CaCO3, followed by the selective removal of the carbonates by washing with HCl. The as-prepared Mn2O3 nanostructures showed very high specific surface area with their subunit particle size of <30 nm, a
