MSE Areas: Nanostructured materials for batteries, electrochromic devices, electrochemical supercapacitors, opto-electronic and sensor applications, thin film rechargeable lithium batteries, intercalation materials

The electrochemical energy laboratory is set up to design and develop high performance materials for sustainable energy applications (mainly electrochemical systems such as batteries, supercapacitors, fuel cells, electrochromic windows, and photoelectrochemical devices). In this respect, our research covers a broad range of activities: new materials design and development, chemical synthesis, materials characterization, property measurements, fabrication of prototype devices and their evaluation, and a fundamental understanding of structure-property-performance relationships of materials. Nanostructured materials including metal oxides and metal chalcogenides are being investigated.
