Quantitative elemental analysis of the pristine, redissolved and recycled Li3InCl6 after separation from different electrode materials via inductively coupled plasma mass spectrometry (ICP-MS) was conducted with an Agilent ICP-MS system 8900 with triple quadrupole (ICP-QQQ) and SPS4 autosampler. The corresponding solid-state electrolytes were weighed as a doublet for sample preparation into centrifuge tubes (Ultra-High Performance Centrifuge Tube, VWR International) in a glovebox under an Ar-atmosphere.
