Carbon Wetting Layer Data with Sodium Hexametaphosphate Additive

A collection of experimental data on carbon wetting layers for molten sodium batteries, comparing the performance of sodium hexametaphosphate (SHMP) against other sodium salts. The data includes results from Scanning Electron Microscopy (SEM) analysis and electrochemical testing of Na symmetric cells. The dataset is associated with a 4.4 MB DOCX file.

Use Cases

• Analyze SEM images to compare structural defects like cracks and voids between SHMP-modified and No-salt carbon layers.
• Model the relationship between salt additive type (e.g., SHMP, NaCl, NaNO3) and measured electrochemical metrics like interfacial resistance and overpotential.
• Compare the adhesion and mechanical stability performance of SHMP against conventional salts such as NaCl, NaNO3, and Na2CO3 from experimental data.

Strengths

• Data is derived from controlled electrochemical testing using Na symmetric cells.
• Includes comparative analysis of multiple salt additives: SHMP, NaCl, NaNO3, and Na2CO3.
• Findings are supported by SEM analysis of the porous carbon network structure.

Limitations

• The dataset is contained within a single 4.4 MB DOCX file, which may require parsing to extract structured data.
• The specific number of data points, rows, or experimental replicates is not provided.
• The data is focused on a specific laboratory study, limiting generalizability without further validation.
