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.

Purpose

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.

Safe, Scalable and Sustainable Battery Recycling

RISE helps you increase recycling rates, meet regulatory requirements and position yourself in a rapidly growing market. We support stakeholders across the entire value chain – from material suppliers and battery manufacturers to recyclers, technology providers and companies with battery-powered products. With strong technical expertise, testbeds and an independent role, we offer concrete solutions tailored to your needs.

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 analyzes are linked to the materials that are exposed. For example, electron microscopy (SEM) can be performed.

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 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.

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.

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).

'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.
