Planning to attend in person? Please note: There are three airports that service the Baltimore/Washington D.C. region (Dulles, Reagan National and BWI).
Parking on campus can be a bit tricky, however, policies are a bit more relaxed during the summer!
- Follow this link to the UMD DOTS website to learn more about parking, and how to avoid pesky citations.
- You may download a visitor parking map here. Note: The Xfinity visitor parking is the closest to A. James Clark Hall.

- Impact of Chemical Crossover in Lithium-ion Cells with Silicon Anode (Ram Manthiram, University of Texas at Austin)
Chemical crossover between electrodes plays a critical role in the performance of lithium-ion cells. While the detrimental impact of crossover from layered oxide cathodes to graphite anode is well known in the literature, the impact of such crossover in cells comprised of high-nickel cathodes and silicon anodes is not fully understood or established. Furthermore, the anode to cathode crossover in such cells needs to be understood as well. This presentation will focus on the understanding developed on such crossovers in cells with high-nickel cathodes and silicon anodes, employing in-depth electrochemical measurements and advanced characterization methodologies.
Oxide-based solid-state Li-batteries (SSLiBs) have the potential to be a transformational and intrinsically safe energy storage solution due to their non-flammable ceramic electrolyte that enables the use of high-capacity Li metal anodes and high voltage cathodes for higher energy density over a much wider operating temperature range. However, their progress has been limited due to electrode/electrolyte interfacial issues. In particular for Li-metal anodes concerns over dendrite formation/propagation and the requirement for elevated temperature and high stack pressure are still prevalent. To eliminate these concerns a rational design of tailored materials, structures, and interfaces in Li-metal anodes will be presented. In addition, demonstration of high-rate Li metal cycling, achieving 100 mA/cm 2 at room temperature with no applied pressure, and progress toward full cells using these tailored materials, structures, and interfaces will be presented.
- Low-Temperature Electrolytes for MicroSi-based Li-ion batteries (Chunsheng Wang)
Silicon anodes offer lower cost and higher capacity than graphite in Li-ion batteries. However, they suffer from fast capacity decay and low Coulombic efficiency in carbonate electrolytes. Using nano-sized alloying anodes can enhance the cell cycle life but also reduce the battery calendar life and increase manufacturing costs. We developed electrolytes that enable micro-sized Si anodes to achieve a long cycle life in a wide temperature range from -40oC to +40oC at lean electrolytes without electrode swelling due to the formation of LiF-rich inorganic SEI on Si. The electrolytes also enable the micro-Si||NMC811 full cells to achieve high performance in wide temperatures.
