The core activities of our research group are development of sustainable/alternative systems for energy conversion and storage, which are vital for the Canadian economy. Development of materials and components play a central role in technological breakthroughs, efficiency improvements, and overall cost reduction of these processes. The current thrust of our activities includes development of materials and catalysts for large-scale rechargeable MnO2/Zn batteries, advanced Li-ion batteries, hydrogen fuel cells, conversion of CO2 and waster water to valued-added chemicals, advanced electrolysis, water treatment, hydrogen fuel cells, and hydrogen storage. Researchers in our lab routinely prepare materials by a variety of methods such as high energy ball milling, wet chemical methods, electro- and electroless deposition, and solid state reactions. X-ray diffraction (XRD) is an indispensable tool for proper characterization of the materials as-prepared, during and after operation in the reactors and cells. XRD allows us to determine the crystallographic phases present, perform quantitative structure analysis, and measure crystallite sizes accurately. Our current XRD equipment requires urgent replacement to maintain research continuity, and software upgrade for advanced phase analysis which is not possible at present. In addition, to learn about the mechanism of failure modes of the materials and electrodes, X-ray analysis is required while the specimen in operation (e.g., X-ray analysis of a working battery). The requested funding will allow our researchers to perform these critical in-situ measurements using a number of techniques including X-ray, Raman and optical microscopy. Without the requested equipment we can not perform our research effectively. Hence, urgent funding is required to purchase a bench-top and economical (but powerful) diffractometer to meet our growing research needs.
