A variety of colloidal chemical approaches has been developed throughout the last decades for the controlled synthesis of nanostructured materials in either water or in organic solvents. Apart from precursors,...
We report an electrochemical study of end-capped glymes dissolving lithium salts as electrolyte solutions for lithium metal batteries. Various electrolyte formulations including triethylene and diethylene glycol dimethyl ethers as solvents and lithium salts employing bis(fluorosulfonyl)imide (FSI −), bis(trifluoromethanesulfonyl)imide (TFSI −), and bis(pentafluoroethanesulfonyl)imide (BETI −) anions are explored. The ions transport properties, the lithium/electrolyte interphase characteristics and the electrochemical stability window are investigated by means of chronoamperometry, electrochemical impedance spectroscopy, galvanostatic cycling, and voltammetry measurements. The comparative study suggests electrochemical properties well suitable for lithium battery application which enable long cycling. The electrolyte solutions are investigated in cells using an insertion cathode material, i.e., lithium iron phosphate (LiFePO 4), and the high-energy lithium metal anode. The results reveal the electrolyte composition has a remarkable effect on the cell performances, and indicate the solutions of LiTFSI salt in either in
Additive manufacturing industries have been focusing on the development of novel ink formulation strategies, that can incorporate functional materials for printing high-efficient electronic patterns for flexible devices. As such printed...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
