The development of materials for energy application requires mastery of material chemistry as well as in depth knowledge of the system requirements. Materials and assembly for the Lithium-ion chemistry has been a practical and intriguing field to study. The main focus of my research is to synthesize new materials and develop new assembly approaches to improve the energy density, increase life, and lower cost of the lithium-ion battery for the vehicular applications. I lead the conductive polymer binder for Si electrode project within the BATT program. I am also part of the team developing the Lithium-ion Cell Fabrication and Testing Procedures at LBNL. I co-developed triethyleneoxide based solid-polymer electrolyte during my Postdoctoral training period, and worked on polyethyleneoxide based polymer electrolyte in my Ph.D. research. Aside from lithium-ion battery research, I also collaborate with researchers in the field of Organic Light Emitting Diodes (OLED), biocompatible materials and biological inspired systems.
- Lithium-ion rechargeable battery: advanced electrode design and formulation, silicon based anode materials, electrode binder design and synthesis, electrolyte and additives.
- Organic light emitting diode (OLED): Light emitting polymer design and synthesis, device assembly and testing, layer and interface diagnostics with FIB and TEM techniques.
- Bio-compatible materials and biological inspired materials
- Expertise in organic and polymer synthesis, and polymer composite technology for advanced energy systems. Develop new polymers, composite materials and structures, and perform structure-function relationship study of the materials and interfaces to understand their fundamental properties in the energy conversion systems. Apply this broad based knowledge of the composite system to improve the performance of energy conversion systems.
