Alike the cited works, ,,, our proposed mechanism also has been previously established , based on the modeling and calculations. , For instance, Sasaki et al used the previously established mechanism justifying the ME, which had been established to explain the thermodynamic origin of VH, that is, the particle-by-particle mechanism.

“…Noteworthy, although the present paper uses the previously established mechanism to explain another phenomenon (ME), however, it does not overlap or conflict with our previous and feature works. The previous paper described the different phenomena, that is, VH, the first cycle overvoltage, and the curves boundaries . In contrast, this paper explains the ME phenomena and its known aspects.…”

To develop energy-storage devices, understanding their charge–discharge behaviors and their underlying mechanisms is mandatory. Memory effect (ME) is among the most important behaviors that should be understood, influencing the batteries’ applications. In this paper, the intercalation batteries’ ME and their features are justified and explained by employing the particles’ bipolarization mechanism. Diffuse regions, located in both sides of the reactant/product phases, turn the particles into dipoles (bipolarized particles) during/after the processes. This bipolarization and subsequent neutralization can explain many charge–discharge behaviors, including the ME. Here, the mechanism explains and justifies all the known features and some aspects of the phenomena which have not been considered so far. According to the proposed mechanism, the aged-neutralized particles react later and in a higher voltage than the fresh-neutralized particles, causing a bump in the curve called the ME. It is the same mechanism that causes the increase in the charge voltage by increasing the open-circuit voltage rest time. Our experiments sufficiently verified the mechanism. In the paper, impacts of the average particle size, relaxation/rest time, discharge cutoff voltage of the memory–writing cycle (MWC), Li-mobility kinetics, current rate, state of charge, depth of discharge of the MWC, boundaries of the charge–discharge curve, and so forth are considered, and their influences on the ME are explained. This mechanism sheds light on the relevant characteristics of the batteries and helps design, tune, control, and engineer the behaviors.

For independency from the fossil fuels and to save environment, we need to move toward the green energies, which requires better energy storage devices, especially for usage in electric vehicles. Li‐ion and beyond‐lithium insertion batteries are promising to this aim. However, they suffer from some inherent limitations which must be understood to allow their development and pave the way to find suitable energy storage alternatives. It is found that each positive or negative electrode material (cathode or anode) of the intercalation batteries has its own behavioral (charge‐discharge) properties. The modification of preparation parameters (composition, loading density, porosity, particle size, etc.) may improve some aspects of the electrode performance, but cannot change the intrinsic property of the electrode itself. Accordingly, these properties are called as the “inherent behavior characteristics” of the active material. It is concluded that the behavior of a specific electrode substance, even following different preparation routes, depends only on diffusion mechanisms. This work shows that the inherent electrode properties can be visualized by representation of current density vs. capacity.

The purpose of this work is to investigate the structure and mechanism of long‐range electronic contacts which are formed by wet mixing and their interaction and relationship with the structure responsible for ion‐transfer within the conductive binder domain of next‐generation LiNi0.6Mn0.2Co0.2O2 lithium‐ion batteries. This paper introduces a novel concept involving an efficient adapted structure model, which includes a bridge structure with two “nested” small and large pore systems, and an effective electrode conduction mechanism involving two “nested” percolation systems. The paper also highlights a limitation in the improvement of the battery performance by percolation systems for electron transfer, which is restricted by pore systems for ion transfer through the ratio of electrical conductivity (σ) and ionic conductivity (κ) as σ/κ = 10. The findings of this paper may provide valuable insight for formulation design and manufacturing of an optimal structure of the conductive binder domain for next‐generation lithium‐ion batteries.This article is protected by copyright.
