Determination of the content of a large number of elements in battery materials including electrolyte, electrodes and separators and casing is performed with screening techniques such as semi-quantitative ICP / MS or with specialized measurements with very small measurement uncertainty.

The composition of all the constituent materials in a battery is absolutely crucial for its function. Both production and recycling processes have requirements for purity and the main composition of materials. Aging processes and usage can also move substances inside a battery altering the function.  In addition to other chemical analysis techniques, inductively coupled plasma mass spectrometry (ICP / MS) in combination with relevant sample processing is a valuable tool for the identification and quantification of many elements. We offer to perform general and very specific measurements on battery material. Examples of elements are Mn, Li, Al, Na, S, Ca, K, Si, Cu, Fe, Mg, Ni, Co and Zn.

Opening Li-ion batteries for detailed studies of aging or breakdown is very useful for increased understanding.
Likewise, other types of batteries can be opened after discussion. Visual assessment as well as chemical and physical analyzes are linked to the materials that are exposed. For example, electron microscopy (SEM) can be performed.

Faliure investigations and aging studies (post mortem analysis) of batteries presuppose that they are opened to expose spacers and active electrode surfaces. This can be done in a glove box environment with an inert atmosphere with control of oxygen and water. Visual inspection of the condition as well as coupled advanced analysis with electron microscope (SEM), chemical specification (XPS / ESCA), Raman and FTIR microscopy can also be performed.

The polar solvents used to dissolve the active salts (eg LiPF6) in Li-ion batteries are often carbonates, eg diethyl carbonate or propylene carbonate. The main composition, impurity profile and degradation products are of interest in production and recycling processes. We offer to quantify and identify these substances.

Chemical analysis of the solvents in Li-Jon batteries is performed using gas chromatography / mass spectrometry both for quantification but also to identify unknown impurities or degradation products. The methodology is very flexible if it covers substances that are in gases at room temperature up to high-boiling oils. Depending on the question, the delivery is adjusted. This type of measurement can also be combined with other measurements to understand a process or supplement a specification.

HF in battery electrolyte is formed when water hydrolyses e.g. LiPF6. HF is seen as a contaminant and gives lower capacity of the battery and destroys certain electrode materials. We perform several determinations of fluorine species including HF in electrolyte.

HF in electrolyte is one of the battery-related measurements we perform. HF is seen as a contaminante in the context of batteries and is often included in the specification for a new or recycled electrolyte. HF is determined using cooled titration and a pH electrode for detection.

Water is an impurity in Li-ion electrolytes. This is because water reacts, breaks down, important components such as the active salt LiPF6. Control of production and recycling processes towards low water levels is of great importance. We offer analysis of water content in, among other things, ketone-based electrolytes.

Water content determinations can be made in several ways based on concentration and matrix. For the electrolytes that are common in Li-ion batteries, we perform customized titrations of water. The method is based on Karl Fischer methodology, both columetric and volumetric. Titrations give a low spread in the measurements and the two types together give a large measurment range, from about 50 ppm to 100%. In case of expected low water levels, consult us about sampling and transport. The risk of contamination is large. We can also provide you with suitable sampling vessels.

RISE in Mölndal conducts research and development of textile fibres, with a special focus on material transition for a sustainable development. Melt spinning poses certain requirements on the material, including high temperature stability and suitable flow properties. We can evaluate the spinnability of newly developed materials.

Melt spinning is the most commonly used industrial fibre spinning method. It’s great advantage is that the method requires only heat, no solvents, to transform polymers into a melt which can be extruded and drawn into thin fibres.

Globally, there is at present a rapid development of thermoplastics from biobased and recycled feedstocks, and consequently melt spinning will be increasingly useful to produce environmentally sustainable textile fibres.

The fibre spinning expertise RISE can support material producers by performing evaluation of the spinnability of new polymer materials. This evaluation requires only small amounts of polymer (approx. 100 grams) and is suitable also for R&D materials.

If the material is found to have good spinnability, larger scale trials and pilot fibre production can be carried out in our equipments for lab-scale and/or semi-industrial fibre spinning.

Several material properties are relevant for spinnability, and our evaluation includes characterisation of:

• Degradation temperature, using thermogravimetric analysis (TGA)
• Melting point and degree of crystallinity, measured by differential scanning calorimetry (DSC)
• Composition analysis, for example by FTIR
• Flow properties (shear viscosity and extensional viscosity) as a function of shear rate and temperature, as measured in a capillary rheometer (Netzsch RH10)
• Melt strength as a function of take-up rate, measured in a capillary rheometer
• Small scale extrusion of monofilaments, in capillary rheometer
• Mechanical characterisation of fibres, by tensile testing

There is currently a transition from fossil-based materials to products based on renewable materials. This transition has led to a need to control the proportion of a material that comes from renewable sources, i.e. is biogenic. We can offer C 14 / Carbon 14 analysis of various materials such as fuels, plastics and chemicals.

As one of the few commercial laboratory in Europe, we have the opportunity to offer accredited C 14 analysis for determination of fossil / biogenic content. To measure a materials biobased content, the only general way is to measure the proportion of the sample's carbon consists of the isotope C 14, i.e. the ratio of the radioactive and stable isotopes of carbon. The method is also suitable for determining C-14 when isotope-labeled substances are used in tracer experiments, for example in studies of drug metabolism. In addition to the analysis service itself, we can also assist with guidance and problem solving.

The sample is incinerated and the formed carbon dioxide is collected. The content of 14C16O2 is determined in an IR spectrometer with extreme sensitivity and selectivity.

The measurement is performed according to ASTM D6866, with the modification that we use an IR technology (Saturated Cavity Ringdown - SCAR) instead of one of the methods mentioned in the standard.

The work include both accredited and non-accredited testing methods. The scope of accreditation is available upon request – please feel free to contact us for more information.

Measurement of the unwanted washboarding on corrugated cardboard is done to check that it does not exceed an acceptable level.

• Washboarding is a regular line pattern that can occur when the liner is glued on the fluting when making corrugated cardboard.
• Corrugated cardboard is the most common material when manufacturing packaging boxes because it has good shock-absorbing properties that protect the product.
• In addition to measurement, we can also sell software license for the measurement method OptiTopo Expert with washboarding toolbox. This software is based on the use of the instrument L&W OptiTopo sold by ABB (formerly Lorentzsen & Wettre).

The measurement gives:

• A quality measure of how large the washboarding effect is.
• The liner's fine-scale surface roughness and craters that often correlate with print quality after the corrugated board surface is printed.
• Illustrative images of the washboarding effect that make it easier to visually compare different samples and use the results in reports and presentations.
