Walter Zeltner, Ph.D. (Water Chemistry) is a physical chemist with some 20 years of experience in synthesizing suspensions of nanoparticulate oxides and in studying the electrochemical properties of these materials. He gained this experience while working as an Associate Scientist at the University of Wisconsin - Madison (UW) until 2007, during which time he authored or co-authored over 30 peer-reviewed publications. Since then, he has worked in a variety of capacities for several companies that have been spun off from the UW, including SolRayo, in efforts to commercialize different aspects of the nanoparticle technology. He served as the Principal Investigator (PI) for SolRayo's Phase II Small Business Technology Transfer Research project that was funded by the National Science Foundation. The project involved developing coatings of nanoparticle ceramic oxides that increase the cycle life of commercial cathode materials used in lithium-ion batteries when operated at relatively high temperatures (~55C). As the PI, he was responsible for directing all aspects of the project, including fabricating candidate coated materials for testing, coordinating testing and data analysis, preparing required reports, and tracking project expenditures. He served as PI on three previous Phase I SBIR studies for different start-up companies.
