We unreveal mechanistic background of the presence of chemical inductive effects in phase separating ion intercalation energy storage materials, in particular lithium iron phosphate (LFP) and lithium titanate oxide (LTO), by applying a detailed phase field model. These materials feature fast (de)int ...

An innovative computationally efficient method for the simultaneous determination of top dead centre (TDC) offset and pressure offset is presented. It is based on characteristic deviations of the rate of heat release (ROHR) that are specific for both offsets in compression phase and expansion phase ...

The paper proposes an advanced continuum level modelling framework characterized by a more consistent virtual representation of electrode topology to enhance prediction capability and generality of porous electrode theory based models. The proposed modelling framework, therefore, establishes the mis ...

Li-ion battery;phase separating material;multi-particle porous electrode;memory effect;
Phase separating Li-ion battery cell cathode materials feature a well-known phenomenon called the memory effect. It manifests itself as an abnormal change in working voltage being dependent on cell cycling history. It was only recently that plausible mechanistic reasoning of the memory effect in Li- ...

Electrochemical impedance spectroscopy (EIS) is essential for non-invasive battery characterization. This paper addresses the challenge of adequate interpretation of EIS spectra, which are often complicated by overlapping internal phenomena occurring on similar time scales. We present, for the first ...

Despite extensive research, understanding the SEI’s formation mechanism, structure, and its impact on battery performance remains challenging due to its complexity. To enable model-based design studies and to enhance understanding and prediction of the macroscopically observable consequences of SEI ...

Phase field models are an important mesoscale method that serves as a bridge between the atomic scale and the macroscale, used for modeling complex phenomena at the microstructure level. Machine learning can be employed to accelerate these simulations, enabling faster and more efficient analyses. Ho ...

Hysteresis is a general phenomenon regularly observed in various materials. Usually, hysteretic behavior is an intrinsic property that cannot be circumvented in the non-equilibrium operation of the system. Herein, we show that, at least with regard to the hysteretic behavior of phase-separating batt ...

To date, a variety of Battery Energy Storage Systems (BESS) have been utilized in the EV industry, with lithium-ion (Li-ion) batteries emerging as a dominant choice. Li-ion batteries have not only captured the automotive market but have also exponentially been used in stationary energy storage secto ...
