This book was released on 2021-06-23 with total page 345 pages. Available in PDF, EPUB and Kindle. 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Rechargeable batteries are one of the crucial ways we are going to solve the sustainable energy crisis. Lithium-ion batteries have been commercialised and are heavily relied upon, however, the scarcity of lithium resources increases the production cost and hinders further application. Additionally, the toxic and flammable electrolyte brings many potential safety hazards including environmental pollution. Looking for low-cost, safe, and environmentally friendly alternatives to LIBs has become a valuable research direction. The modification of batteries is focused on the anode, the cathode and electrolyte. Globally, researchers have moved onto new rechargeable batteries based on multivalent metal ions which have been extensively studied, including K+, Ca2+, Mg2+ and Al3+. However, the electrolyte is a very important component of a battery as its physical and chemical properties directly affect the electrochemical performance and energy storage mechanism. Finding and selecting an appropriate electrolyte system is a crucial factor that must be taken into account to make these post-lithium-ion batteries commercially viable. Until now, it has been challenging to develop a suitable electrolyte with a wide electrochemical stability window and stable anode interface. This book covers all the major ion-battery groups and their electrolytes, examining their performance and suitability in different solvents: aqueous, non-aqueous, solid gel and polymer. It is suitable for all levels of students and researchers who want to understand the fundamentals and future challenges of developing electrolytes.

Available in PDF, EPUB and Kindle. Book excerpt: The main motivation for the organization of the Advanced Research Workshop in Belgirate was the promotion of discussions on the most recent issues and the future perspectives in the field of Solid State lonics. The location was chosen on purpose since Belgirate was the place were twenty years ago, also then under the sponsorship of NATO, the very first international meeting on this important and interdisciplinary field took place. That meeting was named "Fast Ion Transport in Solids" and gathered virtually everybody at that time having been active in any aspect of motion of ions in solids. The original Belgirate Meeting made for the first time visible the technological potential related to the phenomenon of the fast ionic transport in solids and, accordingly, the field was given the name "Solid State lonics". This field is now expanded to cover a wide range of technologies which includes chemical sensors for environmental and process control, electrochromic windows, mirrors and displays, fuel cells, high performance rechargeable batteries for stationary applications and electrotraction, chemotronics, semiconductor ionics, water electrolysis cells for hydrogen economy and other applications. The main idea for holding an anniversary meeting was that of discussing the most recent issues and the future perspectives of Solid State lonics just twenty years after it has started at the same location on the lake Maggiore in North Italy.

Available in PDF, EPUB and Kindle. Book excerpt: The insatiable apatite humanity has for energy provides a great desire for portable battery technology, with large growth and increased development sure to become one of the big achievements of this century. Lithium batteries provide the energy density required by modern devices, however, the flammability and toxicity of the electrolytes currently employed leaves much to be desired in the way of safety. In particular, lithium metal anodes, that take full advantage of the electrochemical properties of lithium and are the focus of this research, are considered too unsafe for commercial applications. Ionic Liquids (ILs) provide the safety and electrochemical stability to facilitate better lithium batteries, however, they still suffer from the disadvantage of typically having a viscosity 1-2 orders of magnitude above conventional solvents. Through a greater understanding of the affect of additives and blending on the transport properties and speciation within the electrolyte, a commercially practical material is closer to development. Screening a range of molecular additives, from common organic solvents to short chain oligoethers, has shown that the viscosity of the additive is not important and that selection of the right structure can dramatically enhance the transport properties and alter the speciation of the lithium ions. Although the carbonates increase the lithium ion diffusivity, their main mode of enhancement in battery electrolytes is their ability to polymerise into suitable Solid Electrolyte Interphase (SEI) layers. Even though tetrahydrofuran (THF) increased lithium diffusion more than the carbonates, its electrochemical instability negates any positive enhancement. Short chain oligoethers, particularly tetraglyme (TG), are an extremely effective additive that essentially removes the detrimental effect on the transport properties of the Ionic Liquid (IL) when lithium salt is added, enhancing the lithium ion diffusivity by more than a factor of 4 at 274 K. Interestingly, the diffusivity and molecular motions of the pyrrolidinium cation remain largely unchanged regardless of the additive that is present. Variable temperature Nuclear Magnetic Resonance Spectroscopy (NMR) spin-lattice relaxation experiments display a clear trend in lithium environment based on the complexing ability of the additive, with the order from the almost unchanged to dramatically different, respectively; Toluene, THF, 1NM3 and TG. Purely ionic electrolytes maintain the full safety aspect that ILs provide, however, the difficulties in maintaining reasonable transport properties while improving lithium electrochemistry are highlighted. The Nmethyl- N-butyl-morpholinium cation exhibited much lower conductivity than analogous structures without an ether oxygen yet its favourable lithium electrochemistry and high temperature cycling performance is promising for high temperature applications or for use as an additive. Binary and ternary mixtures of ILs with lithium salts provide a viable avenue to increase the transport properties and extend the operating temperature of the electrolyte. Using a common cation, N-methyl-N-propylpyrrolidinium, and mixed anions, the binary blend with an anion concentration at a ratio of 2:1, bis(fluorosulfonyl)imide:bis(trifluoromethanesulfonyl)imide, produced a material with a melting temperature more than 20 K lower than either pure component.
