For electrochemical measurements, 2032-type coin cells (MTI Corporation)
were assembled in an argon-filled glovebox. The prepared sample and
lithium foil (Alfa Aesar) were used as the working and counter/reference
electrodes, respectively. The typical mass loading of the active material
was approximately 1.0 mg cm^–2. The electrolyte was
prepared by dissolving 1 M LiTFSI in cosolvents of 1,3-dioxolane (anhydrous,
contains ∼75 ppm butylated hydroxytoluene as an inhibitor,
99.8%, Sigma-Aldrich) and 1,2-dimethoxyethane (anhydrous, 99.5%, Sigma-Aldrich)
at a volume ratio of 1:1. Before preparing the electrolyte, the solvents
were placed in molecular sieves for 24 h to remove moisture. Polypropylene
membranes (Celgard Inc.) were used as separators. Galvanostatic measurements
were performed in the potential range of 1.0–3.0 V vs Li/Li⁺ using a battery cycler (WonATech WBS3000). For the rate capability
tests, the charge rate was fixed at 0.5 C in the constant-current
mode, and the discharge rate was varied from 0.5 to 10 C (1 C = 1675
mA g^–1). CV measurements were obtained in the potential
range of 1.0–3.0 V vs Li/Li⁺ at a scan rate of 0.1
mV s^–1 using a multichannel battery tester (Biologic
VMP3). All electrochemical measurements were conducted at 25 °C.

Characterization of Li-Metal Electrode Morphology

Check if the same lab product or an alternative is used in the 5 most similar protocols

The morphology of the Li-metal
electrodes was examined by field-emission
SEM (Sirion, FEI). In a dry glovebox filled with argon, the Li-metal
electrodes were carefully separated from the disassembled cells after
electrochemical investigations. To remove any residual electrolyte,
the obtained electrodes were gently rinsed with 1,2-dimethoxyethane
(anhydrous, 99.5%, Sigma-Aldrich, USA) and dried under vacuum overnight.
The samples were vacuum-sealed in a PP bottle for safe transfer without
contamination and exposed to air only for a few seconds at sample
loading. To prevent Li-metal contamination, the bonding characterizations
of the electrode surface were carried out via FT-IR (IFS66V/S-HYPERION
300, Bruker Optic) and XPS (Sigma Probe, Thermo VG Scientific) in
a vacuum chamber. The FT-IR analysis was carried out in the wave number
range of 2000–900 cm^–1, and XPS spectra were
calibrated against the hydrocarbon peak at a binding energy of 285.0
eV.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
