Colloidal Antimony Sulfide Nanoparticles as a High-Performance Anode Material for Li-ion and Na-ion Batteries

Abstract

To maximize the anodic charge storage capacity of Li-ion and Na-ion batteries (LIBs and SIBs, respectively), the conversion-alloying-type Sb 2 S 3 anode has attracted considerable interest because of its merits of a high theoretical capacity of 946 mAh g −1 and a suitable anodic lithiation/delithiation voltage window of 0.1-2 V vs. Li + /Li. Recent advances in nanostructuring of the Sb 2 S 3 anode provide an effective way of mitigating the challenges of structure conversion and volume expansion upon lithiation/sodiation that severely hinder the Sb 2 S 3 cycling stability. In this context, we report uniformly sized colloidal Sb 2 S 3 nanoparticles (NPs) as a model Sb 2 S 3 anode material for LIBs and SIBs to investigate the effect of the primary particle size on the electrochemical performance of the Sb 2 S 3 anode. We found that compared with microcrystalline Sb 2 S 3 , smaller ca. 20-25 nm and ca. 180-200 nm Sb 2 S 3 NPs exhibit enhanced cycling stability as anode materials in both rechargeable LIBs and SIBs. Importantly, for the ca. 20-25 nm Sb 2 S 3 NPs, a high initial Li-ion storage capacity of 742 mAh g −1 was achieved at a current density of 2.4 A g −1. At least 55% of this capacity was retained after 1200 cycles, which is among the most stable performance Sb 2 S 3 anodes for LIBs.

Lithiation mechanism of antimony chalcogenides ( Sb 2 X 3 ; X = S, Se, Te) electrodes for high‐capacity all‐solid‐state Li‐ion battery

“…The high capacity during charging also supports the speculated side reaction from the broad peak around 1.7‐2.7 V in CV curves. Similar behavior was also observed by Kumari et al in case of Bi chalcogenides with LiBH 4 as a solid electrolyte 13,28,29 . As per the report, this was also associated to the thermochemical side reaction.…”

“…The alloying mechanism plays an important role in the capacity improvement and also accelerates the reaction kinetics with the formation of Li 3 Sb. In this way, a balance between cyclic stability and capacity enhancement could be achieved 24‐29 . However, no study has focused on the implementation of these anode materials to all‐solid‐state Li‐ion batteries so far.…”

Sodium ion intercalation and multi redox behavior of a Keggin type polyoxometalate during [PMo10V2O40]5−to [PMo10V2O40]27−as a cathode material for Na-ion rechargeable batteries

“…1 Among the various energy storage devices, Liion batteries 2,3 meet the huge energy demands with long cycle life 4,5 and high energy density. [6][7][8][9] Despite these advantages in Liion batteries (LIBs), the growing demand is limited by low reserves, uneven distribution of the source, high costs and safety parameters. 10,11 In the periodic table as Na metal lies just below the Li metal, it shares similar chemical reactivity, electrochemical and ionic properties to lithium; besides, the abundant source and cheap price of sodium makes Na-ion batteries (NIBs) a next promising alternative to LIBs.…”

“…[ 154 ] Therefore, TMC can replace metal oxides as electrode materials. [ 155 ] Compared with TMC such as MoS 2 and WS 2 , the theoretical research capacity of vanadium sulfide is high, but the research on it is far from enough. [ 156 ] The lithium ion insertion electrode material is affected by the number of lithium ion transport units.…”
