Reversible lithium insertion and copper extrusion in layered oxysulfides

Abstract

All of the copper in the layered oxysulfides Sr2MnO2Cu1.5S2 and Sr2MnO2CU3.5S3 may be extruded as the element and the copper ions replaced quasi-reversibly by lithium ions in reductive topotactic ion exchange reactions; dramatic changes in magnetic properties result.

Single‐Phase Cu3SnS4 Nanoparticles for Robust High Capacity Lithium‐Ion Battery Anodes

“…The PXRD study of the cycled anodes at various discharge potentials given in Figure 5a have the species present as indicated in equation (1). [36] As the anode is discharged to lower potential, the CTS NPs dissociate further and upon the total discharge to 0.01 V, the sharp peaks of Li x Sn, Li 2 S and Cu metal which is a buffer matrix imply the total conversion of the material. [36] As the anode is discharged to lower potential, the CTS NPs dissociate further and upon the total discharge to 0.01 V, the sharp peaks of Li x Sn, Li 2 S and Cu metal which is a buffer matrix imply the total conversion of the material.…”

“…The PXRD plot at 1.4 V shows the onset of Li x Sn [34] formation along with the peaks of Li 2 S [35] species formation and Cu metal. [36] As the anode is discharged to lower potential, the CTS NPs dissociate further and upon the total discharge to 0.01 V, the sharp peaks of Li x Sn, Li 2 S and Cu metal which is a buffer matrix imply the total conversion of the material. The FTIR spectroscopy done on the anodes cycled at two selected potentials 0.6 and 0.01 V reveals the electrolyte decomposition due to SEI formation as well as the Li 2 S evolution as evident from Figure 5b.…”

Microwave Absorbing Properties of Ba0.6Sr0.4Fe12-zMnzO19 (z = 0 – 3) Materials in XBand Frequencies

“…The phase identification refers to the research results of Zlatkov, et al [9], Rutt, et al [10], Al-Saie, et al [11], and Jankovskýa, et al [12] for the phase of barium hexa-ferrite (BaFe 12 O 19 ), strontium oxide (SrO), hematite (Fe 2 O 3 ), and manganese oxide (Mn 2 O 3 ), respectively. The refinement result, revealed that manganese substitution in the iron atoms was only able to reach the limit of z = 1.…”
