abstract = {Precise explanation and prediction of the aging behavior of
lithium-ion batteries (LIBs) is essential for
improvingbattery management systems. It is quickly becoming
a hotspot in battery research. Solid electrolyte
interphase(SEI) growth is regarded as the dominant factor of
capacity losses in LIBs. However, the growth of SEI is yet
to beunderstood in more detail due to its complexity. In the
present paper, an advanced voltage-based aging modelusing an
electron tunneling mechanism is proposed and validated by
experiments. This model employs theelectrode voltage as an
input parameter for the first time with a tunneling
mechanism, which is more flexiblethan existing energy-based
approaches and can be used to predict the electron tunneling
(dis)charge cycles. Theproposed model is used to simulate
tunneling current profiles during (dis)charging of graphite,
LTO, and blendSi/C negative electrodes. The simulation
results prove and explain that lower states-of-charge of
LIBs mitigateelectron tunneling and SEI growth, further
reducing calendar aging. That work can be used to describe
batterycapacity losses better and it is crucial for
predicting the state-of-health of LIBs.},
