Abstract Severe capacity decay under subzero temperatures remains a significant challenge for lithium‐ion batteries (LIBs) due to the sluggish interfacial kinetics. Current efforts mitigate this deteriorating behavior rely on high‐solubility lithium salts (e.g., Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), bis(fluorosulfonyl)imide (LiFSI))‐based electrolytes construct anion participated solvation structures. However, such bring issues of corrosion current collector and increased...

Abstract An initial Coulombic efficiency (ICE) higher than 90% is crucial for industrial lithium‐ion batteries, but numerous electrode materials are not standards compliant. Lithium trapping, due to i) incomplete solid‐state reaction of Li + generation and ii) sluggish diffusion, undermines ICE in high‐capacity electrodes (e.g., conversion‐type electrodes). Current approaches mitigating lithium trapping emphasize nanoscaling (<50 nm) minimize diffusion distance, followed by severe solid...
Electric vehicles (EVs), which are becoming increasingly popular, can be charged by either wired or wireless means. The latter, based on power transfer (WPT) technology, is convenient and safe, but pad misalignment one of the major concerns as it causes a reduction in charging level, prolonging process. Therefore, systems with high tolerance to necessary. This study proposes three‐phase bi‐directional (BD‐WPT) system control scheme that offers EV applications. uses simple coil designs for...
Bi-directional inductive power transfer (BD-IPT) systems are preferable for applications such as Electric Vehicles (EVs) and wireless integration of EVs with the utility grid (V2G). In particular, poly-phase BD-IPT used in high rapid charging but their performance is severely compromised by cross-coupling effects between phases misalignment pads or coils. This paper therefore presents a generalized mathematical model to investigate caused pad-misalignments corresponding impacts on flow...

A three phase bi-directional (BD-IPT) system studied with both LCL CL compensations, a mathematical model developed investigate its...
The multiport dc/dc converter with input independent output series structure is simple and efficient for photovoltaic (PV) applications. Through the cascade of sub-modules (SM), has a high step-up ratio to connect MVdc bus. However, it many ports which increase risk short-circuit faults. Therefore, this article proposes fault ride-through (FRT) topology converter. When low-voltage are short-circuited, they can be isolated by blocking switches their own. FRT support voltage faulty SMs avoid...

Photovoltaic power plants are generally far away from loads such as cities and industrial zones. Moreover, long-distance transmission for renewable energy will become an inevitable trend in the future. Cascaded dc-dc converters can reach a high voltage to collect transport photovoltaic energy, with advantages lower costs larger capacities. However, input mismatch may cause large amount of switching harmonic components, resulting dc-link fluctuations, which not only increase volume filter but...
