Transport-Induced Failure of Electrochemical Devices: Batteries and Electrolyzers

 

Abstract

Many electrochemical devices such as batteries, fuel cells, electrolyzers, etc. degrade over time and under various operating conditions. In batteries containing series-connected cells, degradation often occurs if one or more cells exhibit different characteristics than the rest of the cells. Also, batteries are more prone to degradation during charging. Problems with laptop batteries are well known. Fuel cells (especially stacks) also undergo degradation during operation. There is considerable literature on solid oxide electrolyzers, which too degrade under certain operating conditions. Degradation in these devices may manifest as increase in resistance, loss of capacity, or both. In some instances, complete electrode delamination has been observed. In some cases, electrolyte instability may occur. In lithium-ion batteries, lithium dendrites can form. While there are several reasons for degradation, the observation that many electrochemical devices degrade suggests that there may be a common underlying reason which is applicable to all such electrochemical systems. This talk is on the degradation of such electrochemical devices which can occur under transport. A key conclusion is that the chemical potential of an electrically neutral species within the electrolyte corresponding to the mobile ion, may lie outside the range covered by the values at the electrodes (reservoirs), and this can lead to transport-induced instability. Specific examples of solid oxide electrolyzers and lithium ion batteries will be addressed.

Chemical Mapping of the Evolving Material Interface in Liquids

Abstract

A vacuum compatible microfluidic reactor, SALVI (System for Analysis at the Liquid Vacuum Interface) was employed to study the evolving material interface of particles in liquids.  Three case studies will be provided in this talk.  The first study is a model switchable ionic liquid (SWIL) system consisting of 1,8-diazabicycloundec-7-ene (DBU) and 1-hexanol. When CO2 gas is added to the DBU and 1-hexanol mixture, the solvent polarity is known to change. A series of ionic liquids with different CO2 loading was analyzed. Spatial chemical differences were observed within the same ionic liquid, indicating  Inhomogeneity of the ionic liquid. Spectral principal component analysis (PCA) was conducted. Clear distinctions were   observed among SWILs with different CO2 loadings. The loading plots strongly indicate that fully loaded SWILs share similar spectral components as those of the non-loaded ILs. This finding confirms the      hypothesis of the biphasic structure in the fully loaded IL   predicated by molecular dynamic simulation and presents the first physical evidence of the liquid microenvironment of IL determined by liquid ToF-SIMS. Second, we           investigated the chemical structural evolution of the metal organic framework (MOF) formed over different lengths of times using in situ liquid SIMS imaging.  Zn-MOF-74 is the model system.  Zn-acetate is the metal center and DHTA is the ligand linker in a DMF solvent.  MOFs in solvent are analyzed to ascertain the growth mechanism and the   evolution of the MOF structure.  Ex situ XRD, HeIM, and TEM are used to     characterize MOFs to complement the in situ analysis.  MOF surface area measurement and adsorption and desorption testing illustrate that the MOF pore size    becomes smaller over time yet the overall adsorption/desorption properties  mprove due to the increased density of the pores.  Lastly, large colloidal boehmite particles of importance in nuclear engineering and   processing are studied under a variety of pH conditions.  Particle morphological changes are observed using in situ liquid SEM.  Moreover, the solvent and solute compositions are found to relate to the pH conditions, providing direct evidence of the solvation effect via submicron chemical mapping.  The vacuum compatible microchannel in SALVI offers an    Innovative perspective to study the evolving liquid-liquid and solid-liquid   interface.  This approach allows direct visualization of the spatial and chemical heterogeneity in complex liquids by dynamic ToF-SIMS complemented with other imaging and spectroscopy techniques and provides new insights for improved understanding of the evolving material interface.

 Advanced Nanostructured Materials for Selective Separation and Extraction

 

Abstract

In the materials science realm, porous materials, such as polymers, covalent organic frameworks (COFs), and metal organic frameworks (MOFs), are extremely valuable because of their stability and pore size. It is also easy to manipulate their chemistry. Typically, MOFs and COFs have the surface area of a football field, which enables them to capture and store large amounts of gas molecules and use as sensors. Similarly surface functionalization of MOF thin films on magnetic core particles were demonstrated for catalysis and separation applications. During my presentation I will touch up on two different applications (extraction of rare earth elements from geothermal brine solution and separation of noble gases from nuclear reprocessing plants) of MOFs that PNNL is working on.

 

Biography

My research is focused on the development of novel materials for energy applications, including catalysis, energy storage, carbon capture, and nuclear reprocessing. In the past 10 years I conducted both fundamental and applied research on a large number of novel crystalline organic and metal-organic frameworks (MOF) and membrane materials. The results of my research on synthesis, characterization and separation using porous organic and metal organic frameworks were published in more than 50 DOE technical reports and ~130 manuscripts in international peer-reviewed journals, as well as 6 reviews and 5 book chapters, The scientific impact of my research is evidenced by over 6800 citations and H-index of 47 (Google Scholar) attracted by these publications.

In addition to peer-review journals, the results of my work are disseminated through other professional publications. For example, research on MOFs membrane for CO2 separation was featured in 2013 Presidents Budget report; several other publications were featured on external websites, including Department of Energy – Office of Science website. I also contributed to a report to the Department of Energy on the first economic assessment of solid sorbents for CO2 capture from integrated gasification combined cycle (IGCC) power plants and first economic analysis report comparing room temperature separation of Xe and Kr from air to cryogenic separation process.

I supervise research by graduate and undergraduate students and mentor junior researchers. I am engaged with broad scientific community as a Topic Editor for Crystal Growth & Design, Advisory Board member for CrystEngComm and Journal of Coordination Chemistry, Guest Editor for Catalysis Today and community Board of Editor for Cryst. Grow & Des. Network. I also (co-)organize professional meetings at the national and international levels, including “Greenhouse Gas Emissions, Conversions and Utilization” (Denver, 2011), “CO2 Capture, Conversion and Utilization” (San Diego, 2012), “Metal Organic Frameworks for Energy and Fuels” (ACS, Philadelphia, 2012), and “Metal Organic Frameworks for Catalysis Applications” (ACS, Boston, 2015), as well as by facilitating scientific exchange as a discussion leader.

Solution Verification for Large Eddy Simulations
In Computational Fluid Dynamics

Abstract

With the dramatic growth of supercomputers, simulation based design, and ultimately virtual reality, have become increasingly important for the advancement of science and engineering.  Computational fluid dynamics (CFD) provides   computerized solutions for science and engineering problems using modeling, numerical methods, and high-performance computing. In CFD, the continuous partial differential equations are discretized into algebraic equations using numerical methods.  The algebraic equations are assembled and solved to get approximate solutions.  Thus, it is imperative to quantitatively estimate the numerical and modeling errors and associated uncertainties, which can only be achieved through rigorous verification and validation (V&V).  Additionally, guidelines for how to optimize a CFD simulation to obtain a minimum total simulation error are needed.  In this speech, definitions, general methodology and procedures of V&V will be covered. Based on statistical analysis, the “Factor of Safety” method shows advantages over various versions of the grid convergence index method, correction factor method, and least square method for Reynolds-averaged Navier-Stokes (RANS) V&V.  Nonetheless, these methods cannot be applied directly to large eddy simulations (LES) V&V.  Recently, a general framework for LES V&V was developed including a vast number methods based on two Hypotheses, ranging from a sophisticated seven-equation method to a simple single grid method. These methods were evaluated using implicitly filtered LES of periodic channel flows at friction Reynolds number of 395 on eight systematically refined grids. The seven-equation method shows that the coupling error based on Hypothesis I is much smaller as compared to the numerical and modeling errors and therefore can be neglected. The five-equation method based on Hypothesis II is recommended, which shows a monotonic convergence behavior of the predicted numerical benchmark (SC), and provides realistic error estimates without the need of fixing the orders of accuracy for either numerical or modeling errors. Based on the results from seven-equation and five-equation methods, less expensive three and four-equation methods for practical LES applications were derived. It was found that the new three-equation method is robust as it can be applied to any convergence types and reasonably predicts the error trends. It was also observed that the numerical and modeling errors usually have opposite signs in LES, which suggests error cancellation play an essential role in LES. When RANS verification method is applied, it shows significant error in the prediction of SC on coarse meshes. However, it predicts reasonable SC when the grids resolve at least 80% of the total turbulent kinetic energy.
