Multi-scale modelling of Lithium-ion batteries
Tomaž Katrašnik, Igor Mele, Klemen Zelič
Izvirni znanstveni članek
Oznake: Li-ion battery;phase separating material;continuum model;multi-scale modelling;heat generation;thermal runaway;
Multi-scale and multi-domain mathematical models capable of modelling main electrochemical reactions, side reactions and heat generation can reduce the time and cost of lithium-ion battery development and deployment, since these processes decisively influence performance, durability and safety of ba ...

Phase separating electrode materials - chemical inductors?
Klemen Zelič, Igor Mele, Arghya Bhowmik, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: litij ionske baterije;elektrodni materiali;aktivni delci;kvazi 3D model;model porozne elektrode;li-ion batteries;electrode materials;aktive particle;quazi 3D model;porous electrode model;
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 ...

ǂA ǂnew method for simultaneous determination of the TDC offset and the pressure offset in fired cylinders of an internal combustion engine
Urban Žvar Baškovič, Rok Vihar, Igor Mele, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: motorji z notranjim zgorevanjem;termodinamske analize;zamik zgornje mrtve lege bata;zamik tlaka v valju;algoritem izračuna zamika;internal combustion engines;thermodynamic analysis;TDC offset;pressure offset;offset correction algorithm;
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 ...

Advanced porous electrode modelling framework based on more consistent virtual representation of the electrode topology
Igor Mele, Ivo Pačnik, Klemen Zelič, Jože Moškon, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: batteries;Li-Ion;porous electrode models;electrodes topology;NCM;LFP;memory effect;
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 ...

Revealing the thermodynamic background of the memory effect in phase separating cathode materials
Klemen Zelič, Igor Mele, Ivo Pačnik, Jože Moškon, Miran Gaberšček, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: 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- ...

Enhanced porous electrode theory based electrochemical model for higher fidelity modelling and deciphering of the EIS spectra
Igor Mele, Klemen Zelič, Marko Firm, Jože Moškon, Miran Gaberšček, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: Li-ion battery modelling;electrochemical model;electrochemical impedance spectroscopy;NMC;deciphering EIS spectra;
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 ...

Entering voltage hysteresis in phase-separating materials
Tomaž Katrašnik, Jože Moškon, Klemen Zelič, Igor Mele, Francisco Ruiz-Zepeda, Miran Gaberšček
Izvirni znanstveni članek
Oznake: battery;phase-separating materials;Lithium iron phosphate;voltage hysteresis;intraparticle phase-separated;
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 ...
