Investigation of Failure and Gassing in Advanced Lithium Ion Battery Systems with Electrolyte Optimization as a Solution
by Hoffmann, Jennifer, Ph.D., University of Rhode Island, 2018, 89; 10790521
Abstract (Summary)

Stronger emphasis on sustainability has become a necessity amongst all industries, and the automotive industry is no exception. The push to move toward hybrid electric vehicles (HEVs) and electric vehicles (EVs) has resulted in a need for lithium ion batteries delivering higher power over a wide temperature range with improved safety over a long lifetime. To accomplish these requirements, advanced electrode materials such as the high nickel cathode material LiNi 0.8Co0.1Mn0.1O2 (NCM811) or the anode material Li4Ti5O12 (LTO) have been sought after. The high nickel cathode materials come with the desired high capacity suitable for the power needed for automobile applications but comes with safety and cycle life troubles. Looking at the other electrode LTO comes with long cycle life and improved safety compared to the widely used graphite anode but has gassing and capacity setbacks. During this seminar presentation, a deeper look into the industry of lithium ion batteries as well as a review of work focusing on the electrolyte influence on these advanced anode and cathode materials will be discussed.
