Materials Development
Synthesis, chemical and electrochemical characterization of novel electrode materials for batteries and fuel cells. Understanding the mechanisms and structural by chemical, electrochemical, and spectroscopic techniques. Morphological characterization by BET area, particle-size distribution, porosimetry, X-ray diffraction, SIMS, SEM, EDS techniques.
Batteries
Rechargeable battery systems such as nickel-metal hydride, Li-ion, and Li-polymer. Diagnostic studies of rechargeable batteries AC impedance, area-specific impedance analysis, CV, pressure-heat measurements during cell cycling and correlation with calorimetric studies. Performance evaluation under constant current, dynamic stress tests (DST) and pulse discharge. Failure mechanisms using XRD, SEM, EDS, and electrochemical techniques.
Supercapacitors
Development of aqueous and nonaqueous electrochemical double layer and galvanic capacitors for high power applications.
Electrochemical Kinetics
Kinetics of oxygen reduction and generation on electrode surface by AC impedance, rotating disk and rotating ring disk methods. |
