A sodiophilic amyloid fibril modified separator for dendrite-free sodium metal batteries. [Dataset]

Abstract

Sodium (Na) batteries are being considered as prospective candidates for the next generation of secondary batteriesin contrast to lithium-based batteries, due to their high raw material abundance, low cost, and sustainability. However, the unfavorable growth of Nametal deposition and severe interfacial reactions have prevented their large-scale applications. Here we propose a vacuum filtration strategy through amyloid fibril modified glass fiber separators to addressthese issues.

• Collection Method: FT-IR spectrometer (Nexus 870, USA) was used to detect the types of functional groups on the amyloid fibrils powder with an adsorption wavelength range of 1000-4000 cm−1 . XPS measurements of amyloid fibrils were carried out on an X-ray photoelectron spectrometer (XPS, Thermo Scientific Escalab 250Xi) using monochromatic Al Kα X-Ray source. The binding energies obtained in the XPS analysis were corrected by referencing the C 1s peak position (284.48 eV). Raman spectroscopy was obtained from micro-Raman spectroscopy (Horiba, HR Evolution) with a laser radiation of 514 nm. X-ray diffraction patterns were recorded with the X-ray diffractometer equipment (Rigaku D/MAX-2005/PC) using Cu Kα radiation (λ = 1.5406 Å) with a step scan of 0.02° per step and a scan rate of 4° min−1. Microstructure morphology and element analysis were observed by scanning electron microscopy (FEI Helios G4CX) with an accelerating voltage of 5 kV for SEM image capture and 20 kV for EDX mapping. Transmission electron microscopy (TEM) analysis was performed on a FEI Talos F200 operated at 200 kV. Tensile tests were conducted using a tensile stage controller (Shenzhen Sansi UTM4103) with a 20 N load cell at a crosshead speed of 0.5 mm min−1. The elastic moduli of the separators were quantified using peak force quantitative nanomechanics (PFQNM) mode on an AFM (Bruker Dimension Icon with ScanAsyst), and subsequently analyzed using Nanoscope Analysis software. PeakForce tapping mode was adopted in AFM imaging using a ScanAsyst-Air silicon probe. Force spectroscopy mode was utilized to obtain force curves of the samples, with a typical scanning rate of 0.5 Hz and a loading force of 0.5 nN. To ensure accuracy, data was collected at various positions on at least three separate samples, and the moduli of the separators were estimated based on the collected data. In-situ XRD characterization in Na|Al half batteries assembled with the AF5@GF separator or the GF separator: The in-situ XRD measurements were obtained at X-ray diffractometer equipment (D8 ADVANCE, Bruker AXS GmbH Co., Ltd). The Na|Al half battery was assembled using a tailor-made mold with a window for X-ray penetration. The constant galvanostatic discharge curve of the Na|Al half battery was measured by electrochemical workstation (Bio-logic, VSP), and the current density was 1 mA cm-2. The XRD patterns recording frequency was 10 min for the same position.
