Wave-layered dendrite-free lithium deposition with unprecedented long-term cyclability. [Dataset]

Abstract

As the most promising candidate for next-generation batteries, Li metal batteries (such as Li-air and Li–S) have received considerable attention for their ultrahigh theoretical capacity (3860 mAh g−1), the lowest electrochemical potential (−3.040 V versus standard hydrogen electrode), and low density (0.534 g cm−3). Unfortunately, Li dendrite issue in relative to uneven deposition not only reduces the utilization of active Li, resulting in a short cycling life, but also causes safety risk, wherein the rooted dendrite growth enables the connection between electrodes, leading to short circuit or even an explosion. To date, numerous efforts have been devoted to stabilizing the structure of Li metal anode to prevent the formation of Li-dendrites, it is still of great challenge towards long cycle life for high-energy batteries under industrial conditions.

• Collection Method: Powder X-ray diffraction (XRD) patterns were collected on an X-ray diffraction (Rigaku D/MAX-2005/PC) using a filtered Cu Kα radiation at a sweep rate of 2 degree/min, XRD refinement was performed using TOPAS v.5.0 software. The micro-morphologies were observed with FEI Helios G4CX with an accelerating voltage of 5 kV for SEM image capture. Transmission electron microscope (TEM), and elemental mapping were observed on a Talos F200X at 200 kV. The specific surface areas and pore size distribution were measured by a Micromeritics ASAP2020 using nitrogen gas adsorption at 77 K (-196 oC). X-ray photoelectron spectroscopy (XPS) patterns were conducted on a ThermoFisher with Al Kα (1486.71 eV) X-ray radiation (15 kV and 10 mA). The binding energies obtained in the XPS analysis were corrected by referencing the C 1s peak position (284.60 eV). Raman spectroscopy was obtained from Renishaw micro-Raman spectroscopy with a laser radiation of 514 nm. The galvanostatic discharge/charge tests were collected on a LAND CT2001A battery test instrument. The specific capacity and current density were calculated according to the area of the electrodes. Electrochemical impedance spectroscopy (EIS) curves were carried out on a BioLogic VMP3 system with the typical frequency range from 100 kHz to 10 mHz by applying the applied voltage of 5 mV.
