  • Multi-Ionic Lithium Salts for Use in Solid Polymer
    A Dissertation Submitted to the Temple University Graduate Board In Partial Fulfillment of the Requirements for the Degree by Examining Committee Members: ABSTRACT Commercial lithium ion batteries use liquid electrolytes because of their high ionic conductivity (>10-3 S/cm) over a broad range of temperatures, high dielectric constant, and good electrochemical stability with the electrodes (mainly the cathode). The disadvantages of their use in lithium ion batteries are that they react violently with lithium metal, have special packing needs, and have low lithium ion transference + numbers (tLi = 0.2-0.3). These limitations prevent them from being used in high energy and power applications such as in hybrid electric vehicles (HEVs), plug in electric vehicles (EVs) and energy storage on the grid. Solid polymer electrolytes (SPEs) will be good choice for replacing liquid electrolytes in lithium/lithium ion batteries because of their increased safety and ease of processability. However, SPEs suffer from RT low ionic conductivity and transference numbers. There have been many approaches to increase the ionic conductivity in solid polymer electrolytes. These have focused on decreasing the crystallinity in the most studied polymer electrolyte, polyethylene oxide (PEO), on finding methods to promote directed ion transport, and on the development of single ion conductors, where the anions are + + immobile and only the Li ions migrate (i.e. tLi = 1). But these attempts have not yet achieved the goal of replacing liquid electrolytes with solid polymer electrolytes in lithium ion batteries. In order to increase ionic conductivity and lithium ion transference numbers in solid polymer electrolytes, I have focused on the development of multi-ionic lithium salts.

Its catalytic activity has been reported to be significantly enhanced through its use as a composite with various transition metal nitrides.

It focuses on the production of lithium compounds from spodumene minerals. Spodumene is one of the most critical minerals nowadays, due to its high lithium content and high rate of extraction. Lithium is one of the most sought-after metals, due to the ever-growing demand for lithium-ion batteries (LiBs). The data on lithium extraction from minerals is scattered through years of patents, journal articles, and proceedings; hence, requiring an in-depth review, including the comprehension of the spodumene phase system, the phase conversion processes, and the lithium extraction processes. Keywords: lithium review; spodumene processes; thermodynamic of spodumene; lithium extraction 1. Introduction Lithium is the third element of the periodic table. It is the lightest of all solid elements (d = 0.53 g cm 3 at 20 C), has the highest specific heat capacity, the smallest ionic radius of all · − ◦ the alkali metals, and a high electrochemical potential [1].

Cette thèse repose sur un partenariat avec l’entreprise Hutchinson (spécialisée dans le domaine des polymères) qui a cherché à développer un nouveau procédé pour la fabrication des électrodes. Ce procédé par voie fondue a soulevé la problématique du polymère liant utilisé dans les électrodes puisque ce dernier doit être compatible avec le procédé tout en étant utilisable dans des batteries. C’est dans l’optique de trouver et valider un tel polymère que s’inscrit cette thèse sur le polymère HNBR. En premier lieu, nous nous sommes concentrés sur les répercussions du traitement thermique, étape importante du procédé par voie fondue, sur le HNBR.

An order–disorder transition occurs near 360 K. Below that temperature Li2ND can be described to the same level of accuracy as a disordered cubic (Fd3¯m) structure with partially occupied Li 32e sites or as a fully occupied orthorhombic (Ima2orImm2) structure. The high temperature phase is best characterized as disordered cubic (Fm3¯m) with D atoms randomized over the 192l sites. Density functional theory calculations complement and support the diffraction analyses. We compare our findings in detail with previous studies. © 2005 Elsevier B.V. All rights reserved.
