1. Electrochemical Energy Storage Device

Lithium-ion batteries have become the most promising energy storage source for several applications such as intensely pursued for hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) because they are able to provide higher energy density than other rechargeable systems. However, the disadvantages of current materials have problems with high costs, safety concerns and lower power densities which have to be improved. In the future, the study would be focused on developing: (1) low-cost, high energy and power cathode materials such as lithium-riched, spinel and olivine type lithium-ion battery by variety synthetic methods, morphology controlled and modification of the material (2) nanostructured anode materials, Besides, the relationship between the structures and performance would also be investigated. 

2. Solar to Fuel Conversion 

Hydrogen is very promising and clean renewable energy. It can be produced by a so-called "green process" which only requires solar, photocatalyst and harmful chemicals. However, solar-to-hydrogen efficiency is still too low. The study include (1) design and synthesis of materials that can utilize the solar spectrum effectively. (2) modification of the material by deposition and incorporation of cation or anion.

3. Atomic Layer Deposition (ALD)

Atomic layer deposition (ALD) plays a critical role in the electronics industry since the uniform, conformal and high-aspect-ratio coating is difficult to be achieved by traditional techniques such as sputter and CVD as the dimension is going to nano. However, the technique in catalyst and energy fields is less used. The research would be focused on (1) fabrication of energy nanomaterials (alloy, composite oxide) (2) Using ALD to modify the material.
