“…Recently, several novel charging protocols have been proposed to improve full‐cell XFC cycle life. [ 31,32,34,36,39,45,159,160 ] These protocols mainly consider the Li plating limit in the anode as a constraint on fast charging (i.e., 0 V with respect to Li/Li + ). Voltage ramping and seesaw profiles have shown promising results to still achieve significant fast‐charge capacity, while reducing Li plating propensity.…”

Charging lithium‐ion batteries (LiBs) in 10 to 15 min via extreme fast‐charging (XFC) is important for the widespread adoption of electric vehicles (EVs). Lately, the battery research community has focused on identifying XFC bottlenecks and determining novel design solutions. Like other LiB components, cathodes can present XFC bottlenecks, especially when considering long‐term battery life. Therefore, it is necessary to develop a comprehensive understanding of how XFC conditions degrade LiB cathodes. The present article reviews relevant cathode‐focused studies and summarizes the current understanding regarding cathode performance and aging issues under XFC conditions. Dominant aging modes and mechanisms are identified at different length‐scales with electrochemical correlations for LiNixMnyCozO2 (NMC)‐based cathodes. A range of electrochemical techniques and models provide key insights into cathode performance and life issues. A suite of multimodal and multiscale microscopy and X‐ray techniques is surveyed to quantify chemical, structural, and crystallographic NMC‐cathode degradation. Cathode cycle‐life is scaled to equivalent EV miles to illustrate how cathode degradation translates to real‐world scenarios and quantifies cathode‐related bottlenecks that hinder XFC adoption. Finally, the article discusses several cathode cycle‐life aging mitigation strategies with example case studies and identifies remaining challenges.

“…In [19], an intelligent grouping technique is offered that considers the coupling relationship between EV trip data, battery state and other variables, and produces a charging/discharging priority model based on the charging process contribution index. [20] proposes a novel fast charging strategy to charge lithium-ion batteries safely, which includes a voltage spectrum-based charging current profile that is optimized using a physics-based battery model and a genetic algorithm to address the shortcomings of long charging times and charging-related degradations.…”

Promoting the development of green technologies and replacing fossil fuel vehicles with electric ones can abate the environmental anxieties and issues associated with energy supply security. The increasing demand for electric vehicles requires an upgrade and expansion of the available charging infrastructure to accommodate the fast public adoption of this type of transportation. Ethiopia set a pro-electric cars policy and made them excise-free even before the first electric vehicle charging stations were launched by Marathon Motors Engineering in 2021. This paper presents the first ever technical, economic and environmental evaluation of electric vehicle charging stations powered by hybrid intermittent generation systems in three cities in Ethiopia. This paper tests this model using three different battery types: Lead-acid (LA), Flow-Zince-Bromine (ZnBr) and Lithium-ion (LI), used individually. Using these three battery technologies, the proposed hybrid systems are then compared in terms of system sizing, economy, technical performance and environmental stability. The results show that the feasible configuration of Solar Photovoltaic (PV)/Diesel Generator (DG)/ZnBr battery systems provide the lowest net present cost (NPC), with values of $2.97M, $2.72M and $2.85M, and cost of energy (COE), with values $0.196, $0.18 and $0.188, in Addis Ababa, Jijiga and Bahir Dar, respectively. Of all feasible systems, the Wind Turbine (WT)/PV/LI, PV/LI and WT/PV/LI configurations have the highest values of NPC and COE in Addis Ababa, Jijiga and Bahir Dar. Using this configuration, the results demonstrate that ZnBr battery is the most favorable choice because the economic parameters, including total NPC and COE, are found to be lowest.

“…Theoretical approaches, such as numerical simulations [ 9 , 10 , 11 , 12 ] and molecular dynamics (MD) simulations [ 13 , 14 , 15 ], have been extensively used to study ion transport phenomena. As the ion transport phenomenon in PEO is largely due to the nanoscale structure of polymer electrolytes, several studies using molecular dynamics (MD) simulations have been conducted to explore this phenomenon.…”

Atomistic analysis of the ion transport in polymer electrolytes for all-solid-state Li-ion batteries was performed using molecular dynamics simulations to investigate the relationship between Li-ion transport and polymer morphology. Polyethylene oxide (PEO) and poly(diethylene oxide-alt-oxymethylene), P(2EO-MO), were used as the electrolyte materials, and the effects of salt concentrations and polymer types on the ion transport properties were explored. The size and number of LiTFSI clusters were found to increase with increasing salt concentrations, leading to a decrease in ion diffusivity at high salt concentrations. The Li-ion transport mechanisms were further analyzed by calculating the inter/intra-hopping rate and distance at various ion concentrations in PEO and P(2EO-MO) polymers. While the balance between the rate and distance of inter-hopping was comparable for both PEO and P(2EO-MO), the intra-hopping rate and distance were found to be higher in PEO than in P(2EO-MO), leading to a higher diffusivity in PEO. The results of this study provide insights into the correlation between the nanoscopic structures of ion solvation and the dynamics of Li-ion transport in polymer electrolytes.
