Apart from the above models, other structural models of SEI have also been proposed, such as the double layer capacitor model [20], the polymer electrolyte interlayer model [21], and the compact stratified layer model [22]. Although these models provide some insights into SEI, the real behavior of SEI on anodes largely remains a mystery because many factors

Constructing stable and efficient solid electrolyte interphase (SEI) is among the most effective strategies to inhibit the dendrite growth and thus to achieve a superior cycling performance. In this review, the mechanisms of SEI formation and models of SEI structure are briefly summarized. The analysis methods to probe the surface
A capacitor is an electrical circuit element composed of two metal sheets separated by a dielectric material. A capacitor charging with battery E q C q = the charge stored on the capacitor (coulombs, С), Е =the potential across the capacitor (volts, V) С=the capacitance (farads, F) Upon applying potential across a capacitor, charge will accumulate on metal plates until q satisfies
An interesting applied example of a capacitor model comes from cell biology and deals with the electrical potential in the plasma membrane of a living cell (Figure (PageIndex{9})). Cell membranes separate cells from their surroundings, but allow some selected ions to pass in or out of the cell. The potential difference across a membrane is about

In this research, the full-distributed circuit model was used to classify the contribution of interface traps (ITs) and near-interface states to the electrical characteristics of a 4H-SiC MOS capacitor over a wide range of operation. By fitting the measured capacitance and conductance at a certain value of applied gate voltage when the frequency varied from 1 kHz
Traps are omnipresent in practical semiconductor devices. When modeling these devices, the Trap-Assisted Surface Recombination boundary condition adds the effects of charging and carrier capturing/releasing by surface or interface traps. Here, we examine a tutorial model of a metal-oxide-silicon capacitor (MOSCAP) to demonstrate how to use the feature in
The interphase concept was also extended to the other side of the battery, i.e., the cathode, because researchers noticed that, once the potential of the cathode goes beyond certain threshold, e.g., > 4.0 V vs. Li 0, an independent phase would also exist with similar functions to SEI.
Provided by the Springer Nature SharedIt content-sharing initiative The cathode–electrolyte interphase plays a pivotal role in determining the usable capacity and cycling stability of electrochemical cells, yet it is overshadowed by its counterpart, the solid–electrolyte interphase.
Interphase is the result of irreversible reactions between electrode and electrolyte. Because of the reactions, the junction between electrode and electrolyte is no longer clean, as the solid “impurities” produced by the reactions deposit on electrode surface and constitutes an independent phase.
Interfaces and interphases are two separate but closely corrected concepts. Interface has been well understood in classical electrochemistry. Interphase still presents many unanswered questions to us. Knowing how to design interphase holds the key future batteries.
The cathode–electrolyte interphase (CEI) is vital for battery cell capacity and stability but receives less attention than the solid–electrolyte interphase.
