Flexible and conformable energy sources with high energy storage capability and fast charge/discharge rate are needed for emerging applications including wearables, robots and electric vehicles. The power requirements for the operation of various components in these different devices are in different capacity ranges. So far, the developed energy storage devices are in various stages of their technological status. However, the above-mentioned applications require new features and designs that traditional battery or energy storage technologies simply cannot provide. This could be either due to (i) toxicity of material (ii) rigid packaging and high weight (iii) low energy density of flexible batteries and (iv) low lifecycle. This PhD project will develop new flexible and wearable battery based on new nanocomposite-based anode and cathode electrodes. The surface reactions of the electrode with electrolyte will be investigated. The ionic/electron transfer reactions, redox reactions, ionic diffusions, and capacitive performance will be analyzed by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and charging/discharging methods.
The anticipated major activities:
- Formulate and synthesize nanocomposites for anode and cathode electrodes.
- Characterize the atomic- and molecular-level reactions, structural properties, and electrochemical properties of various materials to be used in the new flexible battery.
- Fabricate and characterize the flexible and wearable battery for healthcare applications.
Candidates should have a first class Honours degree or Masters degree at first class/Distinction level in material science, physics, chemistry, electronic/electrical engineering, with a good fundamental knowledge of material preparation.
