However, the growth of SEI is yet to be understood in more detail due to its complexity. In the present paper, an advanced voltage-based aging model using an electron tunneling mechanism is proposed and validated by experiments. This model employs the electrode voltage as an input parameter for the first time with a tunneling mechanism, which is more flexible than existing energy-based approaches and can be used to predict the electron tunneling (dis)charge cycles. The proposed model is used to simulate tunneling current profiles during (dis)charging of graphite, LTO, and blend Si/C negative electrodes. The simulation results prove and explain that lower states-of-charge of LIBs mitigate electron tunneling and SEI growth, further reducing calendar aging.

After obtaining the data efficiency of the trajectory correction hysteresis (TCH) model with the introduction of the transfer fit (TF) method, this work applies the TF TCH for OCV-based SOC correction. The TF method plays a key role as it enables the cell-specific adaptation of an existing TCH model - ageing update is achieved with solely 12 (SOC/OCV) measurement points. With the precise hysteresis model, the developed framework successfully corrects the faulty SOC history, which could originate from a vehicle data logger. Given that two OCV measurement points are available that arbitrarily lie within the SOC history, the SOC correction is achieved by minimising the voltage deviation between the measurement points and the TCH model’s simulation. Identifying the two SOC parameters shift and scale enables subsequent SOC estimation until an additional OCV measurement is available for a further update.
