abstract = {Combining LiNixCoyMn1−x−yO2 (NCM) as cathode with bare
Cu as anode will potentially lead to next-generation
batteries that are smaller, lighter, and can run for longer
periods on a single charge. However, maintaining high
performance and a long lifespan of NCM || Cu cells is
challenging as it can be affected by various factors from
both the cathode and the anode. From the cathode, it is
well-known that transition metal (TM) dissolution
accelerates cell degradation. From the anode, one of the
main challenges is the formation of high surface area Li
deposits which later transform into “inactive Li” or
“dead Li”. In this study, a comprehensive assessment
regarding these competing factors (i.e., TM deposits and
“dead Li”) is discussed. Accelerated TM dissolution is
accomplished by introducing TM-containing additives into the
electrolyte. The effects of these competing factors and
their degradation mechanism are studied quantitatively and
qualitatively through inductively coupled plasma, i.e.,
optical emission spectroscopy and mass spectrometry. The
“dead Li” influence is analyzed quantitatively using gas
chromatography. The results demonstrate the obvious
deleterious impact of dissolved TM ions on cell performance.
At the same time, “dead Li” has also become a notable
factor for a sudden capacity drop.},
