Polystyrene-Al2O3 composite solid polymer electrolyte for lithium secondary battery
In a common salt-in-polymer electrolyte, a polymer which has polar groups in the molecular chain is necessary because the polar groups dissolve lithium salt and coordinate cations. Based on the above point of view, polystyrene [PS] that has nonpolar groups is not suitable for the polymer matrix. However, in this PS-based composite polymer-in-salt system, the transport of cations is not by segme...
متن کاملLow-Melting CaCl2-NaCl-Al2O3 Electrolyte for Direct Electrochemical Reduction Solid Al2O3
The electrical conductivity and density of the low-melting CaCl2-NaCl-Al2O3 systems at 550°C~800°C ranges were respectively measured by the Continuously Varying Cell Constant Technique, ac-techniques and Archimedes method. The materials were applied as the electrolyte for the direct electrochemical reduction solid Al2O3 at 550°C ~800°C. The materials were composed of 71wt.%~87wt.%CaCl2 (corresp...
متن کاملNMR Study of the Solid Electrolyte Interface on a High Performance Lithium Metal Anode
Introduction: Li metal is an ideal anode material due to its low density (0.534 g cm -3 ), the lowest negative electrochemical potential (-3.040 V vs. standard hydrogen electrode) and extremely high theoretical special capacity (3860 mAh g -1 ), which is ten times as high as that of carbonaceous materials. However, several seemingly insurmountable barriers, including limited Columbic efficiency...
متن کاملExploring electrolyte organization in supercapacitor electrodes with solid-state NMR.
Supercapacitors are electrochemical energy-storage devices that exploit the electrostatic interaction between high-surface-area nanoporous electrodes and electrolyte ions. Insight into the molecular mechanisms at work inside supercapacitor carbon electrodes is obtained with (13)C and (11)B ex situ magic-angle spinning nuclear magnetic resonance (MAS-NMR). In activated carbons soaked with an ele...
متن کاملThe Evaluation of Polyethylene/Clay Composite from Solid State NMR
Polymeric nanocomposites based on polyethylene (PE) and Brazilian natural montmorillonite clay (MN) were obtained by melt processing, using a twin-screw extruder. The main objective of this work is focusing on the characterization of composites materials by solid-state nuclear magnetic resonance (NMR). The solid-state NMR measurements were used to observe both polymer matrix (through carbon-13 ...
