Breakthroughs in Novel Li-ion Electrolytes that Enable Extreme Operations
Abstract
New chemistries for Li-ion conducting electrolytes are needed to overcome issues with the incumbent technology, where cells encounter high charge-transfer resistance at high currents or freezing at low temperatures. The centerpiece of this proposed effort is to accelerate breakthroughs in complex electrolyte formulations by high-throughput experimentation (HTE) coupled with machine learning (ML). This proposed research will deepen our fundamental understanding of Li-ion transport across the solid/liquid interface to develop next-generation electrolytes for high-performance LIBs that are capable of operating in extreme environments. Breakthroughs in electrolytes that can integrate seamlessly into current battery manufacturing processes will enable mission-critical applications to maintain U.S. Navy preeminence.The proposed work draws upon Johns Hopkins University Applied Physics Laboratory s expertise in battery development, fundamental electrochemistry, high-throughput experimentation, and computational techniques including ML and molecular dynamics simulations. Recognizing the extensive history of lithium-ion battery development spanning decades, we acknowledge the reliance on time-consuming experimental data collection. Our approach aims to expedite the discovery of novel electrolytes using HTE and computational methods, enabling the development of tools to enhance LIB technology while fostering chemistry and materials breakthroughs. The successful outcome of this project will position the U.S. Navy to swiftly prototype batteries for deployment in environmentally-challenging regions.
