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. 

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 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…

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 …

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…

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…

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…
