Conversion of Lithium Chloride into Lithium Hydroxide by Solvent Extraction KU Leuven
UNLABELLED: A hydrometallurgical process is described for conversion of an aqueous solution of lithium chloride into an aqueous solution of lithium hydroxide via a chloride/hydroxide anion exchange reaction by solvent extraction. The organic phase comprises a quaternary ammonium chloride and a hydrophobic phenol in a diluent. The best results were observed for a mixture of the quaternary ammonium chloride Aliquat 336 and 2,6-di-tert-butylphenol ...
Lithium polymer electrolytes based on sulfonated poly(ether ether ketone) for lithium polymer batteries KU Leuven
© 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim. We studied a lithium-ion conducting polymer based on sulfonated poly(ether ether ketone) (SPEEK) doped with lithium bis(trifluoromethane)sulfonimide (LiTFSI). Self-standing membranes were prepared by the solvent-casting technique with a LiTFSI loading of 0 to 30 wt.-%. The thermogravimetric analysis curves showed that the SO 3 H groups decompose earlier in the SPEEK-LiTFSI membranes than in ...
Boron extraction using selective ion exchange resins enables effective magnesium recovery from lithium rich brines with minimal lithium loss Ghent University
Magnesium hydroxide is a commodity chemical, produced in almost pure form from seawater through precipitation. Even though Li brines contain high concentrations of Mg2+ cations, the precipitation of Mg(OH)(2) from them is not common. Rather it is typically coprecipitated with other salts and becomes a waste. The crystallization of chemical-grade Mg(OH)(2) from a Li+ rich brine that contained 3.1 g/L Mg2+ and 1.3 g/L Li+, was investigated by ...
Electronic Structure and Thermochemical Properties of Small Neutral and Cationic Lithium Clusters and Boron-Doped Lithium Clusters: Lin0/+ and LinB0/+ (n = 1–8) KU Leuven
The stability, electronic structure, and thermochemical properties of the pure Li(n) and boron-doped Li(n)B (n = 1-8) clusters in both neutral and cationic states are studied using electronic structure methods. The global equilibrium structures are established, and their heats of formation are evaluated using the G3B3 and CCSD(T)/CBS methods based on the density functional theory geometries. Theoretical adiabatic ionization energies (IE(a)) for ...
Lithiation and Delithiation Mechanisms of Gold Thin Film Model Anodes for Lithium Ion Batteries: Electrochemical Characterization Hasselt University
Lithium Ion batteries have to be significantly improved to fulfill the challenging needs in electromobility or large scale energy storage technology. In this context the use of model electrodes such as single-crystals or thin films allows well-defined mechanistic studies. Here we present a detailed electrochemical investigation of the lithiation-delithiation behavior of Au thin film model electrodes in ionic liquid electrolyte. Cyclic ...
Lithium salts as a treatment for COVID-19: Pre-clinical outcomes Hasselt University
Introduction: Identifying effective drugs for Coronavirus disease 2019 (COVID-19) is urgently needed. An efficient approach is to evaluate whether existing approved drugs have anti-SARS-CoV-2 effects. The antiviral properties of lithium salts have been studied for many years. Their anti-inflammatory and immune-potentiating effects result from the inhibition of glycogen synthase kinase-3.& nbsp;Aims: To obtain pre-clinical evidence on the ...
liquid thermal management of a lithium ion capacitor module Vrije Universiteit Brussel
This paper presents the development of a thermal management system for an energy storage system based on lithium-ion capacitors. In the proposed study, a liquid cooling method for a LiC module that comprises 12 cells has been investigated. In this sense, a 3D thermal model coupled with liquid cooling plates has been developed in order to test its effectiveness and the potential it could represent in comparison with other cooling strategies. The ...
Lithium nitrate mediated dynamic formation of solid electrolyte interphase revealed by in situ Fourier transform infrared spectroscopy Hasselt University
A stable solid electrolyte interphase (SEI) plays a vital role in the cyclic stability and Coulombic efficiency (CE) of high-performance lithium-sulfur (Li-S) batteries. It is recognized that the LiNO3 additive can stabilize the SEI of the lithium electrode. However, the exact mechanism of the LiNO3 additive on the SEI of the lithium electrode remains unclear. In this work, we first revealed the mediation mechanism of LiNO3 additive on the ...
