abstract = {Due to the increasing demand for lithium-ion batteries
(LIBs) in recent years, the demand for resources has also
risen. As a result, the amount of LIBs that have reached the
end of their life is increasing, leading to stricter
guidelines that require certain proportions of recycled
materials in the production of new LIBs. Typical recycling
strategies start by deactivating, dismantling and shredding
LIBs, thereby generating blackmass consisting of active and
inactive materials (e.g. Li, Mn, Ni, Co, Cu and organic
carbonates). However, black mass is a non-standardized
resource, and its composition and purity vary depending on
the respective process. 1,2 Therefore, it is essential to
characterize and quantify its composition in order to make
use of this highly variable resource stream while
maintaining quality and safety.This work aims to identify
and quantify organic electrolyte residues in black mass
without further sample preparation. To achieve this, the
samples were agitated using a headspace sampler and then
analyzed by gas chromatography-mass spectrometry (GC-MS) and
flame ionization detector (FID). Linear and cyclic
carbonates such as dimethyl carbonate, ethyl methyl
carbonate, and ethylene carbonate, as well as aging products
such as 2,5-dioxahexanedioic acid dimethyl ester (DMDOHC),
were detected. The identification results were compared to
those achieved by thermodesorption and solid-phase
microextraction.Overall, this study demonstrates a method
for identifying and quantifying organic electrolyte residues
in black mass, which can aid in the development of more
efficient and sustainable recycling processes for
LIBs.References(1) Peschel, C.; van Wickeren, S.; Preibisch,
