Who we are

The Nanoionic Materials Group is focusing on design, synthesis and printing of metal oxides and sulfides-based nanoionic materials for wearable electronics (including sensors, memories and transistors), as well as energy storage and conversion materials (including Li-ion batteries, Zn-ion batteries, supercapacitor electrodes, solid-state electrolytes and electro-catalysts).


Research program

This group focuses on developing solution-processed, printable and flexible nanoionic materials for cost-effective and energy-efficient wearable electronics, including artificial synaptic devices, self-powered battery and strain sensors.

Bioinspired flexible haptic memory materials for artificial sensory nerves

This project aims to develop next-generation haptic memory materials for the applications of artificial sensory nerves, which can precisely detect, process and respond to mechanical stimuli. The project expects to achieve this aim by mimicking the functions of biological haptic memory system and integrating highly sensitive tactile sensors and synaptic devices into artificial sensory nerves.


Engineering nanoionic interfaces towards high-performance cathode coatings

This project aims to develop novel cathode coating materials towards more durable and powerful energy storage devices. Lithium ion battery will be constructed based on perovskite oxides to provide high capacity and stability for potential applications in electric cars, mobile phones and the internet of things.


High-performance metal oxide inks for printable memory arrays

This project aims to develop next-generation printable memory devices with low cost and excellent stability. The goal will be achieved by developing a new class of metal oxide nanomaterials-based inks and large-scale printing technology, through optimising the synthesis, printing process and electrode configuration. 


Phase and defect engineering of high-performance catalysts for solar energy conversion

This project aims to explore innovative concepts to engineer the phase and defects in metal sulfide nanomaterials for highly efficient electrochemical water splitting. A scalable hydrothermal method will be applied for high-yield production based on our unique thermal-decomposition facility. The phase and defects of sulfide materials will be engineered through tuning the reaction solvents and temperature, which is critical for controlling the active sites.
