“…The Sn 3d 5/2 and Sn 3d 3/2 were detected at 487.5 eV and 496.4 eV, due to the spin‐orbital splitting photoelectrons . As shown in Figure (c), P 2p spectrum depicts two main peaks at 134.3 eV and 140.0 eV, which may correspond to phosphorus in Sn 4 P 3 and phosphate respectively . At the same time, two small peaks at 130.1 and 130.9 eV can be attributed to the P 2p 3/2 and P 2p 1/2 for the residual red phosphorus .…”

“…Figure (a) shows the CV result of pure Sn 4 P 3 , which is executed within the potential range of 0.01–3.0 V at a scanning rate of 0.2 mV s −1 . In the first cathodic sweep, a broad cathodic peak ranging from ∼1.1–0.6 V can be assigned to the multi‐step reaction between lithium and phosphorus ,,. Subsequently, another reduction peak around ∼0.27 V corresponds to the alloying reaction between tin and lithium as well as the formation of solid electrolyte interface (SEI) film, which cause the distinct difference between the first and succedent cycles .…”

Through a one‐step solvothermal approach, the carbon nanotubes‐decorated Sn4P3 nanohybrid with intertwined scaffold structure and enhanced electroconductivity is successfully composed as anode material in lithium‐ion batteries, using nontoxic red phosphorus and SnCl2 as starting materials. The special architecture of the nanohybrid exhibits more active sites for lithium ions and buffers the huge volume expansion. When used as anodes in lithium‐ion batteries, the material shows superior electrochemical properties, 976.5 mAh g−1 after 300 cycles under a constant current density of 500 mA g−1 and 480.0 mAh g−1 even at a high rate current of 2000 mA g−1. This excellent electrochemical behavior can be attributed to the 3D network of CNTs and its critical synergic effect with Sn4P3.

“…As reported in the literature [8,9], Sn 4 P 3 shows initial reversible capacity as high as 900 mAh g −1 and by controlling the electrical potential window in galvanostatic charge and discharge testing, it maintains a reversible capacity above 400 mAh g −1 after 50 cycles. Reducing the size and morphology of Sn 4 P 3 particles [14,15] and doping of a small amount of Fe [16] and Mn [17] into Sn 4 P 3 are also effective for further improvement of the cycling stability. Moreover, complexing the carbon materials with nano-structured Sn 4 P 3 particles significantly enhances both the rate performance and cycling stability [18,19,20,21,22,23,24,25].…”

Characterization of Sn4P3–Carbon Composite Films for Lithium-Ion Battery Anode Fabricated by Aerosol Deposition

We fabricated tin phosphide–carbon (Sn4P3/C) composite film by aerosol deposition (AD) and investigated its electrochemical performance for a lithium-ion battery anode. Sn4P3/C composite powders prepared by a ball milling was used as raw material and deposited onto a stainless steel substrate to form the composite film via impact consolidation. The Sn4P3/C composite film fabricated by AD showed much better electrochemical performance than the Sn4P3 film without complexing carbon. Although both films showed initial discharge (Li+ extraction) capacities of approximately 1000 mAh g−1, Sn4P3/C films retained higher reversible capacity above 700 mAh g−1 after 100 cycles of charge and discharge processes while the capacity of Sn4P3 film rapidly degraded with cycling. In addition, by controlling the potential window in galvanostatic testing, Sn4P3/C composite film retained the reversible capacity of 380 mAh g−1 even after 400 cycles. The complexed carbon works not only as a buffer to suppress the collapse of electrodes by large volume change of Sn4P3 in charge and discharge reactions but also as an electronic conduction path among the atomized active material particles in the film.

“…Organic-based electrode-materials can ensure the safety and cycle performance of a lithium secondary battery, and have the characteristics of bendable deformation, high specific energy, wide operating temperature range, long storage life, small self-discharge, and no memory effect, and can be used according to requirements [1][2][3][4][5]. Charge and discharge do not reduce battery performance, among other advantages [6,7]. Various organic molecules have been examined toward obtaining organic-based electrodes, such as conducting polymers, electron-donor/acceptor molecules, metal-clusters, and organic radical molecules [8][9][10].…”

A novel nitroxyl radical polymer poly(TEMPO-acrylamide-co-sodium styrene sulfonate) (abbreviated as poly(TAm-co-SSS)) was synthesized using 4-acrylamido-2,2,6,6tetramethylpiperidine (AATP) copolymerized with styrene sulfonate sodium (SSS). AATP was synthesized through a substitution reaction of acryloyl chloride. Meanwhile, poly(4-acrylamido-2,2,6,6-tetramethylpiperidine-1-nitroxyl radical) (PTAm) was prepared as a control sample. Then, the structures of products were characterized by nuclear magnetic resonance spectroscopy ( 1 H-NMR), Fourier transform infrared spectroscopy (FT-IR), high performance liquid chromatography-mass spectrometry (HPLC-MS), differential scanning calorimetry (DSC), X-Ray photoelectron spectroscopy (XPS), and electron paramagnetic resonance (EPR), respectively. Additionally, the electrochemical impedance spectra (EIS) and the charge-discharge cycling properties were studied. The results demonstrated that the poly(TAm-co-SSS) with the side group of sodium sulfonate adjacent to TEMPO group exhibits a better charge-discharge cycling stability than that of the PTAm. Moreover, the charge specific capacity of the poly(TAm-co-SSS) is larger than that of the PTAm. Besides, the first coulombic efficiency of poly(TAm-co-SSS) is higher in comparison with that of PTAm. These superior electrochemical performances were ascribed to the synergistic effect of sulfonate ions group and nitroxyl radical structure, which benefits the improvement of charge carrier transportation of the nitroxyl radical polymers. Consequently, the nitroxyl radical poly(TAm-co-SSS) is promising for use in organic radical battery materials, based on the good electrochemical properties. such as nitroxide, phenoxyl, and galvinoxyl radicals. Due to the fact that radical polymers are completely amorphous and lack π-conjugation, charge transport occurs locally and through a reversible oxidation-reduction (redox) reaction mechanism, the radical polymers are expected to become a new generation of electrode materials [11,12].As a typical radical polymer, poly(4-acrylamido-2,2,6,6-tetramethylpiperidine-1-nitroxyl radical) (PTAm) indicates that it can be used as a novel, metal-free cathode material or long-period rechargeable devices [13,14]. Moreover, the stable amphoteric nitroxide block copolymers which were synthesized by block copolymerization were promising to be used as the EPR probes for bioimaging in vivo [15]. The electrochemical properties of the PTAm have been studied to confirm its potential for application in new electrode materials [16,17]. However, although good cyclability was usually reported [18][19][20], the TEMPO-substituted polyacrylamide was generally soluble in the electrolyte, leading to loss of capacity over time [21]. Crosslinking of the polymer was then a suitable option to improve the charge-discharge cycling stability [22]. In order to improve electrical properties of organic electronic polymers as electrode materials, ion-bearing repeat units were intentionally added to the macromolecular architecture of PTMA...
