Advanced in situ x-ray diagnostic tools for understanding material transformations in batteries expo
Abstract
While most batteries operate within a narrow operating temperature window (e.g. 0C-45C), there is an increasing interest in energy-,dense batteries for task-specific applications, such as sub-surface and underwater applications. These environments require batterie,s to operate at thermal extremes. Fundamentally, external operating conditions related to environment and/or external operating cond,itions (e.g. fast charge) can impact the performance and degradation of a battery system. This proposal intends to examine how therm,al gradients impact material transformation in conventional lithium ion batteries and lithium metal batteries. These battery systems, are known to plate lithium metal and degrade cathode materials under certain operating conditions. --This proposal will examine non,-equilibrium operating conditions as means to suppress degradation mechanisms, fast charge, and improve the overall safety of batter,y systems. To accomplish this goal this proposal outlines a range of experiments from benchtop (meso) to synchrotron (nano) to track, battery charging dynamics and material transformations during realistic operating conditions. Advanced imaging cells will be develo,ped for operando imaging under thermal gradient conditions. X-ray and electron imaging techniques will understand how thermal gradie,nts contribute to uniform and heterogenous electrodeposition and dissolution. The work is fundamental and seeks to advance next gene,ration energy storage systems for Naval applications.
