Lithium-ion technology represents the current state-of-the-art in rechargeable batteries. Its high energy and power density compared to older systems like Pb-acid, Ni-Cd, or Ni-MH makes it particularly valuable for applications in portable devices and transportation. While Li-ion cells using standard materials such as lithium cobalt oxide for the cathode and graphite for the anode have been widely commercialized, improvements to energy densities, cycle life, and safety are necessary to enable further applications (i.e. electric vehicles, microscale devices). Generating new cathode and anode materials and improving their performance characteristics are central to advancing lithium battery technology.
Our team is currently studying the synthesis and detailed characterization of next-generation lithium battery materials and systems. We have developed novel methods for thin film deposition (including the versatile layer-by-layer technique) for application in ultrathin rechargeable cells and have undertaken fundamental investigations of catalyst and electrolyte function in Li-O2/Li-air batteries.
