This book was released on 2020 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The energy density of lithium ion batteries (LIBs) is limited by the capacities of the electrode materials. Lithium metal is a promising anode material for future LIBs due to its high theoretical specific capacity (3,860 mAh/g) and low redox potential (-3.04 V vs. standard hydrogen electrode). However, lithium plating in liquid electrolyte will form Li dendritic structure and subsequently penetrate the porous polymeric separator, resulting in battery short circuiting. A straightforward method to suppress the growth of lithium dendrites is to replace the liquid phase electrolyte with a solid-state one. Among different solid-state electrolyte candidates, solid polymer electrolyte (SPE) is advantageous due to its flexible nature and low-cost raw material. However, SPE typically exhibits low ionic conductivity compared to its liquid electrolyte counterpart, which thus could result in restricted use in battery applications. In this work, a rational approach to achieve highly ionic conductive and electrochemically stable SPEs will be discussed. A phase-diagram was firstly mapped out to provide guidance in designing a composite electrolyte with high ionic conductivity at room temperature. The thermal and electrochemical stability of SPE were then characterized. A dual-salt base electrolyte with lithium bis(oxalate)borate (LiBOB) and bis(trifluoromethanesulphonyl)imide (LiTFSI) exhibited excellent electrochemical stability from the passivation layer formed between the electrode/electrolyte interface. In addition, SPEs based on crosslinked fluoropolymer and poly(ethylene glycol) diacrylate (PEGDA) were investigated. Those properties of SPE enable the fabrication of solid-state batteries with lithium metal as an anode. Lithium plating/striping experiments and battery tests were conducted, and the results indicated that the dual-salt SPE could be a promising candidate electrolyte for next generation solid-state rechargeable battery. Sodium ion batteries display good performance yet with limited protection for the inevitable sodium dendrite growth if coupled with metallic sodium electrode, which is an adverse phenomenon that would eventually result in the deterioration of the battery. SPEs with superior ionic conductivity and outstanding electrochemical stability are promising for the all solid-state sodium batteries in grid-storage applications. In this study, a transparent free-standing SPE membrane comprising sodium perchlorate (NaClO4), PEGDA and plastic crystal molecules was fabricated. This sodium based SPE exhibits high sodium-ion conductive property (over 0.925 mS/cm at 30 oC) while being electrochemically stable. A rational approach has also been designed and achieved by using the phase diagram. The NaClO4-based SPE can not only exhibit excellent electrochemical stability with metallic sodium electrode, but also provide remarkable current rate and long-term cycling performance for the solid-state sodium metal batteries (SMB).

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries (LIBs) are ubiquitous for applications in consumer electronics, electric vehicles, and grid-scale energy storage. Despite rapidly increasing demand, modern LIBs face significant challenges with regards to their safety and energy density. Additionally, the rigid nature of existing LIBs precludes their use in emerging applications in flexible/wearable electronics. Polymeric materials promise to address many of the issues facing LIBs, yet the existing polymers used commercially fall short of this goal. In this work, we design functional polymer materials to address three major challenges for next-generation LIBs. We explore the structure-property relationships of these polymer architectures in the context of ion transport, mechanical properties, and electrochemical performance. In the first project, a new polymer electrolyte is designed to replace the flammable liquid electrolyte in conventional LIBs. We study the effect of lithium ion coordination in polymer electrolytes and discover a modified polymeric backbone that loosely coordinates to lithium ions. The loose coordination of this new polymer electrolyte enables an improved lithium transference number of 0.54, compared to 0.2 achieved in conventional polymer electrolytes. This polymer electrolyte is demonstrated to operate effectively in a battery with a lithium-metal anode. In the second project, the learnings of the lithium coordination environment from the first project are used to design a multifunctional polymer coating to stabilize high energy density lithium metal anodes. We combined loosely-coordinating fluorinated ligands dynamically bonded with single-ion-conductive metal centers. The resulting supramolecular polymer network functions as an excellent lithium metal coating, allowing for achievement of one of the highest-reported coulombic efficiencies and cycle lives of a lithium metal anode. A systematic investigation of the chemical structure of the coating reveals that the properties of dynamic flowability, single-ion transport, and electrolyte blocking are synergistic in improving Li-metal coating performance. This coating is applied in a commercially relevant lithium metal full-cell and increases the cycle life over two-fold compared to an uncoated anode. The final project uses supramolecular polymer design to create ultra-robust ion transport materials. We show that when soft ion conducting segments are combined with strong dynamically bonded moieties in the polymer backbone, the ion transport properties can be decoupled from the mechanical properties. This decoupling enables for the creation of polymer electrolytes with extremely high toughness and high ionic conductivity. These supramolecular materials enable the fabrication of stretchable and deformable batteries that demonstrate respectable energy density even when stretched to 70% of their original length. Overall, the work demonstrated in this thesis provides a robust understanding towards designing polymer networks with tunable ion transport and mechanical properties. Additionally, the polymer materials demonstrated here provide promising avenues toward improving the safety, energy density, and flexibility of LIBs.

Download or read book Polymer Electrolyte Discovery Via Rational Design and High Throughput Methods written by Michael A. Stolberg and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage of electrical energy is a cornerstone in the global endeavor to lower greenhouse gas emissions-in particular, electrochemical energy storage in the form of batteries can enable the electrification of transport through electric vehicles, as well as aid the transition to renewable energy generation such as wind and solar through stabilizing the grid and mitigating intermittency. Lithium-ion batteries, a pioneering technology to enable portable electronics, are seeing increased use in transportation and grid-scale applications due to their high energy density, and greatly decreasing production costs over the past decade. However, current lithium-ion batteries are reaching the theoretical energy density and must adhere to higher safety standards as they see use in larger scale formats. The next generation of cheaper, safer, and more energy-dense batteries will be enabled by advances in electrolytes which are the focus of this work. In this thesis, we focus on solid polymer electrolytes, which have the potential to enable more energy-dense batteries, and display improved safety compared to the highly flammable and toxic liquid electrolytes in use today. We detail our work in two main areas: the rational design of highly dissociative ionenes, and the development of a high throughput platform to increase the scale and speed of polymer electrolyte research. In the former, we investigate the impact of anion dissociation energy on ion conduction in solid polymer electrolytes via a novel class of ionenes prepared using acyclic diene metathesis polymerization of highly dissociative, liquid crystalline, fluorinated aryl sulfonimide-tagged ("FAST") anion monomers. These polyanions form well-ordered lamellae that are thermally stable and provide anionic channels for ion hopping. Electrochemical impedance spectroscopy and differential scanning calorimetry experiments, along with nudged elastic band calculations, suggest that cation motion in these materials operates via an ion hopping mechanism, which is enabled by the highly dissociative nature of FAST anions. In parallel, we developed a high throughput platform to accelerate electrolyte research. We detail the engineering problems and solutions which resulted in an estimated 100X increase in sample throughput with vastly less researcher effort. The platform is then leveraged in two case studies, first by performing the largest one-to-one comparison of lithium and sodium ion conduction in poly(ethylene oxide) to date, and secondly, the platform is employed in a machine learning-guided Bayesian optimization system to explore and optimize the ionic conductivity of electrolytes based upon poly(caprolactone). This work sets the stage for continued automation and data-driven design of polymer electrolytes for safer and more energy-dense batteries.

This book was released on 2019-09-25 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis makes significant advances in the design of electrolytes and interfaces in electrochemical cells that utilize reactive metals as anodes. Such cells are of contemporary interest because they offer substantially higher charge storage capacity than state-of-the-art lithium-ion battery technology. Batteries based on metallic anodes are currently considered impractical and unsafe because recharge of the anode causes physical and chemical instabilities that produce dendritic deposition of the metal leading to catastrophic failure via thermal runaway. This thesis utilizes a combination of chemical synthesis, physical & electrochemical analysis, and materials theory to investigate structure, ion transport properties, and electrochemical behaviors of hybrid electrolytes and interfacial phases designed to prevent such instabilities. In particular, it demonstrates that relatively low-modulus electrolytes composed of cross-linked networks of polymer-grafted nanoparticles stabilize electrodeposition of reactive metals by multiple processes, including screening electrode electrolyte interactions at electrochemical interfaces and by regulating ion transport in tortuous nanopores. This discovery is significant because it overturns a longstanding perception in the field of nanoparticle-polymer hybrid electrolytes that only solid electrolytes with mechanical modulus higher than that of the metal electrode are able to stabilize electrodeposition of reactive metals.

This book was released on 2022-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this review, different types of electrolytes and their electrical and mechanical properties have been reported and studied to evaluate their effect on LIB performance. It was noticed that the electrolyte component and solvent in polymer electrolytes have a great influence on the ionic conductivity, Li+ migration, interfacial contact between electrolyte and electrode, mechanical properties, and the performance of the entire battery. The morphology of incorporated additive materials (nanoparticles, nanowires, nanofillers, salt, etc.) may well contribute to the amelioration of the ion transport pathway, which raises the lithium-ion conductivity. A basic understanding of the chemical reaction routes and the electrolyte structure would facilitate innovation in the battery. The structural, electrochemical, and mechanical properties of new promising materials should be investigated in advance for application in advanced lithium-ion batteries. The electrochemical behavior is inextricably related to the structure. IL-based solid polymer electrolytes appear as a promising material for long-term lithium-ion batteries despite showing low ionic conductivity but exhibiting more advantages than conventional carbonate electrolytes such as good safety, stability, good electrochemical performance, good mechanical stability, and enhanced energy density. Since solid electrolytes exhibit low ionic conductivity, ILs used in SPEs increased their conductivity. In a battery, porous materials appear to offer good properties in terms of lithium ionic conductivity, with no leakage and low interface resistance, and gel-based LIBs demonstrate a good working performance, long cycling life, and high energy density. Good polymer electrolytes need to be highly conductive, safe, highly mechanically and thermally stable, and easy for film formation.
