“…1e) for SnS 2−x P x /RGO and SnS/RGO show two peaks for the P-C bond (134.4 eV) 43 and P 5+ (139.1 eV). 44 In addition, an apparent shoulder peak presented at 130.4 and 131.1 eV can be assigned to the P-Sn bond. 45 The result indicates that some P atoms successfully replaced S atoms during the phosphating process, which is consistent with the results of XRD and EPR.…”
The reasonable design of electrode materials with heterojunction and vacancy is a promising strategy to elevate its electrochemical performances. Herein, tin-based sulfide composites with heterojunction and sulfur vacancy encapsulated by...

“…The charge process of the FePSe 3 -FeSe 2 /CIIPTCDA full cell over a potential range of 0.5-3.4 V corresponds to the discharge process of the FePSe 3 -FeSe 2 / C half-cell and the charge process of the PTCDA half-cell. 71 As shown in Fig. 7B, an FePSe 3 -FeSe 2 /CIIPTCDA full cell provides a discharge specic capacity of 87 mA h g −1 (based on the mass of the FePSe 3 -FeSe 2 /C anode) aer 200 cycles at a current density of 0.1 A g −1 .…”
Layered heterostructures have gained significant attention as potential platforms for energy storage because of their unique electronic and interfacial characteristics. Engineering heterojunctions in a rational, efficient, and effective manner is...
“…Therefore, research should be focused on Sn-based conversion-alloy anode materials such as oxides, sulfides and selenides. In addition, Sn-based binary alloy materials such as SnP 99 and SnSb 100 are also the focus of future research. 93 Copyright 2018, The Royal Society of Chemistry.…”

Potassium-ion batteries (PIBs) are considered one of the most promising alternatives to lithium-ion batteries due to the abundant and widely distributed potassium (K) resources and low redox potential of K/K+...
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.
