abstract = {Cyclic aging tests of lithium-ion batteries are very
time-consuming. Therefore, it is necessary to reduce the
testing time by tightening the testing conditions. However,
the acceleration with this approach is limited without
altering the aging mechanisms. In this paper, we investigate
whether and how thermal transients accelerate the aging. The
tests are performed on NMC/graphite pouch cells by applying
temperatures in a range of 5 °C to 45 °C to the cell
surface. The results show, that an accelerated capacity loss
can be achieved in comparison to the reference cell at a
steady-state temperature of 25 °C. However, capacity
difference analysis (CDA) prognoses a covering layer for the
transient cells, which is confirmed upon post-mortem
analysis. We suspect the origin to lie in the dynamics of
temperature fields and current distribution during
temperature changes when charging. More specifically, areas
of higher temperature in the cell lead to high local current
densities and plating. Subsequently, high temperatures
promote the reaction of the plated lithium with electrolyte.
The results show that thermal transients are a critical
condition for lifetime and safety and should be treated with
caution as they can occur during real life operation.},
