                      hexafluorophosphate (LiPF6), lithium
                      bis(fluorosulfonyl)imide (LiFSI) is being investigated as a
                      conducting salt for lithium manganese-rich cathodes (LMR)
                      and micro-crystalline silicon anodes (μ-Si). Nevertheless,
                      its behavior towards the aluminum (Al) current collector and
                      stainless-steel (SUS) coin cell parts limits its application
                      under operating conditions requiring potentials higher than
                      3.9 V vs. Li|Li+. Using a mixture of organic carbonate-based
                      solvents, various functional additives, and LiPF6 lithium
                      salt concentrations up to 1.0 M, the instability issue of
                      the Al current collector in the presence of LiFSI is
                      avoided. However, stainless-steel dissolution remains, being
                      confirmed by both potentiodynamic measurements and SEM
                      morphology investigations of the coin cell components after
                      linear sweep voltammetry measurements carried out to 5.0 V.
                      The results also indicate that the amount of stainless-steel
                      dissolution is influenced by both the LiFSI amount in the
                      electrolyte and the quality (grade) of stainless-steel used.
                      Using Al-coated SUS 316L coin cell parts and/or high
                      concentration electrolytes (HCE) with LiFSI (≈ 4 M LiFSI),
                      the observed stainless-steel dissolution process can be
                      fully avoided, allowing the evaluation of the
                      electrochemical performance of LMR cathodes with μ-Si
                      anodes in LiFSI-based electrolytes.},
