SpectraPower LLC offers complete battery and battery materials analytical services. This includes both our in-house capabilities as well as managing sample harvesting and sample preparation for out-sourced characterization and data analysis.
In-House
-
Gurley Air Permeability Testing: testing porosity of films by air permeability
-
Low Pressure Swelling Measurements
-
Peel/ Pull/ Tensile Strength Testing: testing adhesive properties of a film on a substrate: i.e. ceramic coatings of separators
-
Environmental Testing
-
Precise Technical Measurement (Micrometer/ Goniometer/ Scale)
-
Thermal Shrinkage Testing: measures the amount a battery separator shrinks when exposed to high temperatures, which is crucial for assessing potential safety issues like thermal runaway, as significant shrinkage can lead to internal short circuits within the cell due to the closer proximity of the electrodes when heated
Managed/Out-Source
-
SEM/ EDS and FIB-SEM/ EDS: high-magnification imaging of material structure. Electrode and separator layers
-
GCMS (Gas chromatography and mass spectroscopy): composition analysis of battery electrolytes
-
IC-MS & LC-MS (ion chromatography [IC] & liquid chromatography [LC] with mass spectroscopy): identification of battery materials; electrolyte, anions, and cations
-
ICP-OES (Inductively coupled plasma - optical emission spectrometry)
-
DSC (Differential Scanning Calorimeter): determining heat capacity of battery materials
-
