Advanced hybrid nano materials for energy storage devices

Preferred major field of study or minimum required skills

Any major in science or engineering, prefer with wet lab skills but not mandatory.

Scholarly significance/intellectual merit

This project aims at synthesis, characterization, fabrication and testing of modified graphene based electrode materials for high energy density lithium ion battery for energy storage. A low temperature hydrothermal method will be utilized for growing metal oxide nanowires on graphene surface resulting higher surface area for electrode electrolyte interaction which improves the lithium ion diffusion rate. Therefore, this new nanowire/graphene hybrid anode material could enhance the specific capacity and charge–discharge rate of lithium ion battery.

Research question(s)

    1. What is the optimized hybrid material geometry for maximum energy density?
    2. How does the inorganic vs organic materials interface affect charging/discharging rate?
    3. Whether there is any feasibility of integrate energy storage devices in structural materials without sacrificing structural integrity.

Methods/techniques/instruments to be learned/utilized

Wet lab nano mateirals synthesis, hydrothermal, centrifuging, filtering.
