Book excerpt: Lithium (Li) deposition is a problem in Li batteries (LB) – both Li metal (LMB) and Li-ion (LIB) batteries – which limits their performance in terms of power and energy density. Two trends can be identified in the advancement of LBs concerning the problem of Li deposition: optimization of the existing system (the state-of-the-art LIBs) and further development of cell components such as electrolytes. This work addresses both approaches. In the first part, this study investigates Li deposition in LMB and LIBs. A novel method to study the Li-based transport mechanisms in LIBs is introduced. Later the kinetic deviations between anode and cathode as a consequence of aging and the relation of these deviations to the occurrence of Li-plating are discussed. In the second part, the applicability of PEO-based solid polymer electrolytes for LMBs to overcome the Li plating issue is investigated. The introduction of various interfacial interlayers at the cathode/electrolyte interphase was studied to improve the electrochemical stability of the cells. Cells with an in-situ electro-deposited interlayer showed the best cyclability.

Book excerpt: Ever since the publication of Fenton and Wright's work on ionically conducting polymers in 1973, the potential application of solid polymer electrolytes to solid state lithium batteries has lead to an extensive investigation of their transport and electrochemical properties. Recent modeling studies on lithium/insertion cathode cells, including the design scale-up for both unipolar and bipolar configurations indicates the possibility of achieving high energy and power densities well in excess of the present advanced batteries. The recently reported work on polymer electrolyte batteries that operate from -20 C to +100 C demonstrates the utility of this new class of lithium batteries. Keywords Polymers electrolytes; Solid state battery; Lithium battery.

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 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rechargeable lithium ion batteries are revolutionary energy storage systems widely used in portable electronic devices (e.g., mobile phones, laptops) and more recently electrical vehicles. The conventional liquid electrolytes in the lithium ion battery brought about safety problems such as fire and explosion. Related safety accidents (e.g., cell phone explosion, laptop fire, plane smoldering, etc.) have been reported many times. This also eliminates the possibility of using lithium metal as anode material which has much higher theoretical specific capacity in comparison with commercial graphite electrode because of the growth of uncontrolled lithium dendrites can lead to short circuit and other serious accidents. Solid polymer electrolytes have many advantages over conventional liquid electrolytes. They are light-weighted, non-volatile and have much better safety features than liquid electrolyte. Meanwhile, they are also better than the ceramic electrolyte in terms of their excellent flexibility and processability. Currently, low ionic conductivity of solid polymer electrolytes (e.g., polyethylene oxide (PEO)) at ambient temperature still hinders their practical application. Ionic liquids (ILs) are non-flammable and have negligible volatility. Its ionic conductive nature, excellent chemical stability, and good electrochemical stability enable them to be regarded as useful components for next generation battery electrolytes. In this thesis work, focus will be placed on synthesis and characterization of ionic liquid tethered organic/inorganic hybrid polymer electrolyte with high room temperature ionic conductivity. Moreover, their electrochemical properties and prototype battery performances were also looked into. The use of highly conductive solid-state electrolytes to replace conventional liquid organic electrolytes enables radical improvements in reliability, safety and performance of lithium batteries. Here in chapter 2, we report the synthesis and characterization of a new class of nonflammable solid electrolytes based on the grafting of ionic liquids onto octa-silsesquioxane. The electrolyte exhibits outstanding room-temperature ionic conductivity (~4.8 10-4 S/cm), excellent electrochemical stability (up to 5 V relative to Li+/Li) and high thermal stability. All-solid-state Li metal batteries using the prepared electrolyte membrane are successfully cycled with high coulombic efficiencies at ambient temperature. Good cycling stability of the electrolyte against lithium has been demonstrated. This work provides a new platform of solid polymer electrolyte for the application of room-temperature lithium batteries. In chapter 3, an organic-inorganic hybrid solid electrolyte with ionic liquid moieties tethered onto dumbbell-shaped octasilsesquioxanes through oligo(ethylene glycol) spacers was synthesized. The hybrid electrolyte is featured by its high room-temperature ionic conductivity (1.210-4 S/cm at 20 oC with LiTFSI salt), excellent electrochemical stability (4.6 V vs Li+/Li), and great thermal stability. Excellent capability of the hybrid electrolyte to mediate electrochemical deposition and dissolution of lithium has been demonstrated in the symmetrical lithium cells. No short circuit has been observed after more than 500 hrs in the polarization tests. Decent charge/discharge performance has been obtained in the prepared electrolyte based all-solid-state lithium battery cells at ambient temperature. In chapter 4, hybrid polymer electrolyte network (XPOSS-IL) synthesized by crosslinking the individual dendritic POSS-IL was investigated. To be specific, after grafting mono-broninated hexaethylene glycol to the POSS cage, 1-vinyl imidazole was adopted for the subsequent quarternization reaction. Then the chain end double bonds underwent free radical crosslinking process to produce XPOSS-IL. The ionic conductivity of LiTFSI dissolved XPOSS-IL is 5.4 10-5 S/cm at 30 . By adding a small fraction of ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI), the ionic conductivity increases to 1.4 10-4 S/cm at room temperature. It is also found that EMITFSI will enhance the anodic stability of XPOSS-IL. The Li/LTO and Li/LFP cell assembled with X-POSS-IL-LiTFSI/EMITFSI demonstrates capability of delivering high specific capacities at room temperature and elevated temperature.

Book excerpt: Every electrochemical source of electric current is composed of two electrodes with an electrolyte in between. Since storage capacity depends predominantly on the composition and design of the electrodes, most research and development efforts have been focused on them. Considerably less attention has been paid to the electrolyte, a battery’s basic component. This book fills this gap and shines more light on the role of electrolytes in modern batteries. Today, limitations in lithium-ion batteries result from non-optimal properties of commercial electrolytes as well as scientific and engineering challenges related to novel electrolytes for improved lithium-ion as well as future post-lithium batteries.

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.
