abstract = {Understanding battery aging mechanisms is critical towards
identifying and improving upon performance bottlenecks.
Aging protocols which can quickly identify and monitor
degradation of cells can help expedite solid-state battery
development by predicting the possible long-term aging trend
of cells in a time efficient manner. In this work, the
degradation behavior of
$In/InLi|Li_6PS_5Cl|NCM83:Li_6PS_5Cl$ cells was investigated
using two different accelerated aging protocols: (1)
calendar aging and (2) cycle aging. Cells with various
cut-off potentials were investigated using the two aging
protocols showing significantly greater performance
deterioration under calendar aging relative to cycle aging.
Applying distribution of relaxation times analyses obtained
from impedance spectroscopy, the cathode–electrolyte
interfacial resistance evolution is found to be the dominant
degradation mechanism during calendar aging while changes at
the anode–electrolyte interface are influential during
cycle aging tests. The aging protocol and analyses applied
in this work can potentially be further extended to other
systems to help understand degradation processes and quickly
screen cells for optimization.},
