Electrolyte solvent composition -chemical analysis

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.

The future is electric! Batteries and the rapid development in the area entail a huge shift from fossil energy throughout society, in households, industrial applications and in mobility and smart cities. Electrification and storag…

Determination of water content in electrode material

The water content needs to be as low as possible in all materials included in a Li-ion battery build. The water content of the solid electrode sheets can be determined with our Karl-Fischer set-up.

Water content determination in battery electrolytes

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 importa…

Opening of batteries-post mortem analysis

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 …

Determination of elements in battery materials

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 speciali…

Determination of HF in battery electrolyte using titration

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 spec…

Determination of lead, cadmium and mercury in primary batteries

In order to be able to label primary batteries with the Nordic Ecolabel, these must, among other things, meet the limit values ​​for the content of lead (Pb), cadmium (Cd) and mercury (Hg).

Thermal Runaway of li-ion batteries; studies of gases and heat release

Performance and safety are key features for batteries to fully penetrate the car industry. The demand for higher specific capacity and power for electric vehicles does, however, imply that more energy is available leading to an in…
