Abstract Despite the prevailing dominance of lithium‐ion batteries in consumer electronics and electric vehicle markets, growing apprehension over lithium availability has ignited a quest for alternative high‐energy‐density electrochemical energy storage systems. Rechargeable featuring calcium (Ca) metal as negative electrodes (anodes) present compelling prospects, promising notable advantages density, cost‐effectiveness, safety. However, unlocking full potential rechargeable Ca particularly hinges upon strategic identification or design positive electrode (cathode) materials. This imperative task demands expeditious synthetic routes tailored their meticulous design. In this Perspective , we mainly highlight development cathode materials accentuate unparalleled promise solid‐state metathesis designing diverse array high‐performance

Black phosphorus (BP) and its two-dimensional derivative (2D-BP) have garnered significant attention as promising anode materials for electrochemical energy storage devices, including next-generation fast-charging batteries. However, the interactions between BP light metal ions, well how these influence BP’s electronic properties, remain poorly understood. Here, we employed density functional theory (DFT) to investigate effects of monovalent (Li+ Na+) divalent (Mg2+ Ca2+) ions on valence structure 2D-BP. Molecular orbital analysis revealed that adsorption cations can significantly reduce band gap, suggesting an enhancement in charge transfer rates. In contrast, had minimal impact preservation 2D-BP’s intrinsic electrical properties. Energetic analyses indicated extent primarily governs ability modulate structure, especially under high-pressure conditions where are close proximity 2D-BP surface. Moreover, polarization calculations that, compared with cations, induced greater polarization, disrupting symmetry pristine further influencing characteristics. These findings provide a molecular-level understanding ion properties during ion-intercalation processes, calculated diffusion barrier results potential effective material lithium-ion, sodium-ion, magnesium-ion batteries, though performance may be limited calcium-ion By extending our 2D-BP, this work contributes design efficient reliable technologies, particularly

Abstract This research addresses the issue of State Charge (SOC) prediction for electric vehicle batteries by employing a dynamic Kalman neural network model. The model is optimized using Genetic algorithm to adjust weights. Additionally, strategy involving support vector machines optimization proposed. involves preprocessing data, selecting appropriate kernel functions training, and merging results enhance stability Results indicated that Dynamic Neural Network (DGKNN) achieved minimum error percentage only 0.1529% when correction coefficient was set 0.7. DGKNN consistently exhibited lowest percentage, average absolute error, mean square root handling small, medium, large datasets. For instance, in small dataset, 0.1518, 0.0604. findings demonstrated proposed high real-time accuracy predicting battery SOC, enabling monitoring operating parameters. method this study can accurately predict state charge, extend life packs, improve performance vehicles. It has important significance promoting development industry.
