Interrogating Thermal Stability of Solid-State Batteries
Abstract
Approved for Public ReleaseInterrogating Thermal Stability of Solid-State BatteriesExpansion of the Navys unmanned underwater vehic,le (UUV) fleet is limited by the energy density and thermal stability of lithium-ion batteries. Safety is paramount in UUV applicati,ons, particularly for vehicles launched from submarines or combat ships. Solid-state batteries (SSBs) are promising candidates for n,ext-generation energy storage by substituting liquid electrolytes and graphite anode in conventional lithium-ion batteries with soli,d electrolytes and energy-dense lithium metal anode. They are expected to be ideal solutions to battery safety challenges because of, their high intrinsic thermal stability due to the absence of the liquid electrolyte and their ability to mechanically restrain the,growth of lithium dendrites. However, SSBs also contain intrinsically resistive solid-solid interfaces. This project seeks to fundam,entally interrogate the thermal stability of solid-state batteries due to chemical, electrochemical, and mechanical interactions at,various solid-solid interfaces and underlying crosstalk mechanisms between the solid-state cathode, solid electrolyte, and lithium m,etal anode, using a combined experimental and computational analytics approach.
