The Lithium Battery, from a Dream to Domination of Energy Storage.
Lithium-ion batteries have come from an idea in 1972 to dominate electrochemical energy storage today. They are now in a position to enable the large-scale introduction of renewable energy, as well as electrifying transportation, which will leave a cleaner and more sustainable environment for the next generation. There are ample scientific opportunities to further improve their performance and safety. Today’s cells attain only 25% of their theoretical value. However, as the energy density is increased, the safety tends to be compromised. Examples will include: the soft TiS2 lattice, the layered oxides, LiMO2, and Li2VOPO4, a proof of concept for a two-electron transfer. These opportunities and the technical challenges that need to be overcome will be described in order to open up a discussion.
ABOUT THE SPEAKER:
M. Stanley Whittingham’s research interest and expertise includes elucidation of the limiting mechanisms, chemical and structural, of intercalation reactions using a variety of synthetic and characterization approaches, both in-situ and ex-situ. Development of new materials and new synthetic approaches.
Whittingham was recently awarded the Nobel Prize in Chemistry for his development of lithium-ion batteries. He and his team discovered that holding lithium ions between plates of titanium sulfide created electricity. The lightweight lithium-ion batteries power laptops, tablets, cellphones and most electric cars. They have laid the foundation for a wireless, fossil fuel-free society.
The research interests of the materials chemistry group are in the preparation and chemical and physical properties of novel inorganic oxide materials. Much of their effort is targeted at finding new materials for advancing energy storage. Recently, they have discerned the critical role that single-phase reactions play in the discharge of battery electrodes. Their goal is to significantly improve the storage ability of electrochemical devices so as to make renewable solar and wind energy viable and to enable electric vehicle range and cost. Their research involves much materials characterization at the major National Laboratories.
