- Material science, including polymer materials (ionogel and hydrogel electrolytes, binder for lithium batteries), exfoliated 2D materials (TMD and MXene) and nanofiber composite materials

- DTV diagnose method and modelling for lithium-ion batteries

- Supercapacitors and actuators


Research Highlights

1. Self-recovering Tough Gel Electrolyte with Adjustable Supercapacitor Performance

GPE

A self-recovering gel with integrated functions synthesized via self-initiated UV poly­merization is described. It offers an effective platform for a gel electrolyte to attain adjustable supercapacitor performances for energy-storage devices.

2. 3D-Printed Structural Pseudocapacitors 

XCT

Direct metal laser sintering is used to create 3D hierarchical porous metallic scaffolds which are then functionalized with a co-electrodeposition of MnO2, Mn2O3, and doped conducting polymer. This approach of functionalizing metal 3D printed scaffolds thus opens new possibilities for structural energy storage devices with enhanced performance and lifetime characteristics.

Structural energy storage devices have the potential to transform products such as aerial vehicles, cars and consumer electronics. In article number 1600167, Xinhua Liu, Billy Wu, and co-workers use direct metal laser sintering to create 3D hierarchical scaffolds with high mechanical strength. Functionalisation with MnOx-PEDOT:PSS imparts the structure with pseduocapacitive properties and multi-scale x-ray tomography highlights how this approach improves device performance and lifetime.
