The Technology Development group combines capabilities in advanced battery materials synthesis, battery testing, electrochemical characterization, and spectroscopy on advanced electrode materials to solve energy storage problems. Our group maintains strong connections with industry and the academic research community that allows us to maintain a leadership role in developing functional materials for electrochemical energy storage.
The key capabilities of this group include:
- Full Cell Development based on combinations of cell components to create high-energy-density lithium-ion batteries. We are focused on
- Synthesis of Ni-rich LIB cathodes; performance optimization using various coatings and construction of cation concentration gradients with the particles.
- Evaluation of carbon-based anode materials, lithium metal systems, and Li4Ti5O12-based (LTO) technology. LTO systems are being investigated as a component of full cells for fast charging applications.
- Various liquid electrolyte systems that contain new solvents, salts, and functional additives. Investigation of the role of sintering in solid state oxide systems.
- Mixed chalcogenide [SxSey] cathodes have been developed to work in lithium-ion cells. The mixed chalcogenide active species help mitigate performance degradation issues through advanced encapsulation strategies while investigating novel electrolytes that can suppress polysulfide/polyselendie diffusion
- Li-air (Li-O2) battery systems: enable high energy density, energy efficiency, and highly reversibility approaches for Li-Air systems that combine innovation in electrolytes and catalysis, with extensive computer modeling and use of advanced characterization techniques.
- Hybrid Li-ion / Li-air (Li-O2) systems: development of electrochemical processes in mixed electrode well-defined systems
- Lithium Superoxide (LiO2) battery: Exploration of a new concept using a lithium-oxygen conversion reactions with extensive computer modeling and use of advanced characterization techniques to guide the effort.
- Na-ion, Na-air, K-ion, K-air battery systems represent emerging cathode and anode materials for energy storage applications.
