Density of NCM Ternary Cathode Material

Data Summary

• Average: 4.5769 g/cm3
• Standard Deviation: 0.0014 g/cm3

Value for Battery Industry

• High T.A.P. density of precursors is expected to obtain a high volumetric energy density.
• The true density is a good indicator of purity and composition of the cathode which can be used to improve the overall performance of the battery.
• Monitoring true density of the electrode material ensures stability of the slurry coating and drying process

Instrument Details

The AccuPyc uses Gas Pycnometry and the GeoPyc uses a unique displacement technique to determine the:

• True, absolute, and skeletal density
• Apparent volume and density
• Envelope volume and density
• Bulk volume and density

Combining data from these two techniques enables the determination of the percent porosity and total pore volume

Instrument Details

Mercury porosimetry is a uniquely valuable technique which delivers speed, accuracy and the comprehensive characterization of many sample properties:

• pore size, 3nm to 500 µm
• total pore volume
• total pore surface area
• percent porosity
• sample densities (bulk and skeletal)
• particle size

Our extensive range of gas adsorption analyzers offer convenient solutions to realize your R&D, quality control, and manufacturing needs.

• Pore size can be measured from 0.3nm to 300nm using a variety of different models
• Water vapor adsorption studies allow the investigation of a material’s sensitivity towards water

Value for Battery Industry

• The SediGraph is the only instrument that can precisely report weight percent of particles <0.1μm.
• Industry leader for rough electrode and other precursor materials.
• Optimize particle size ratio of cathode and solid electrolyte to maximize the energy density.

Instrument Details

The SediGraph remains the global standard for particle size analysis by sedimentation after five decades, whether in a rugged production environment or a controlled laboratory setting.

• Sedimentation uses well understood physical laws and easy to measure properties that do not require trial and error modeling
• Provides complete sample mass accountability and quantifies the fine content outside the measurement range
• Uses higher material concentration than many other techniques ensuring a representative sample
