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.

Purpose

The use of the adapted columetric Karl Fischer titration to determine water coupled to an oven makes it possible to thermally extract water from many materials. Electrode materials, or other material, is cut into a suitable atmosphere, usually in a glovebox, and placed in a sample container that fits the oven. An inert gas stream leads the water to the titration vessel where quantification takes place. Titration provides low spread between measurements and can detect about 50 ppm water in a sample.

Battery testing - Performance and aging test on Li-ion battery cells

We offer electrical cycling of battery cells and modules in different operating temperatures and charging / discharging processes. We have access to a large number of test channels, which means that we can perform the test processes on up to 180 battery cells and 32 battery modules at the same time. We can also perform testing on battery packs.

Fire safety / Education offer

Battery Fire Safety

Lithium-ion batteries give us amazing opportunities, but there are also challenges to overcome. Among other things, you need to consider safety aspects such as the risks involved and how to prevent them.

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 importance. We offer analysis of water content in, among other things, ketone-based electrolytes.

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.

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 specialized measurements with very small measurement uncertainty.

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 species including HF in electrolyte.

'Black mass' analysis for battery recycling

To pave the way for optimizing battery recycling processes, a proper analysis of ‘black mass’ and spent battery components before and after recycling is very important.
