Summary: Organic materials have attracted great interest as promising electrode materials for next generation batteries due to their abundant resources, environmental friendliness and rich functional groups. However, their development is impeded by the fast capacity decay caused by the high solubility of organic electrodes in liquid electrolyte. In this study, a free-standing MXene paper was introduced as an interlayer for the first time to overcome this issue. The MXene interlayer successfully blocked the dissolution of the cathode, leading to significantly enhanced capacity retention in the configured cells. The performance enhancing mechanism of the MXene interlayer was also investigated.

Summary: Nanocarbons, including carbon nanotubes and carbon nanofibers, were coated on a nickel foam surface via chemical vapor deposition. This unique structure served as a three-dimensional current collector for lithium-sulfur batteries, providing space to accommodate electrode materials. The coated nanocarbons shortened the path of electron transport, absorbed lithium polysulfides, and accelerated their conversion kinetics, thereby suppressing the shuttle effect. Additionally, the rigid framework of the nickel foam constrained the movement of electrode compositions, contributing to the stability of the Li-S batteries.

Summary: The electrochemical properties of Dy on liquid Sn electrode in LiCl-KCl molten salt were studied using various electrochemical methods. The formation of Dy-Sn solid solution ((Dy-Sn)(solution)) was observed when Dy was deposited on liquid Sn. The electrode process was reversible and diffusion-controlled, with a diffusion coefficient of Dy(III) in LiCl-KCl molten salt measured at 10(-5) cm(2) s(-1). The solubility and diffusion coefficient of Dy in liquid Sn were assessed using coulometric titration (CT) and chronopotentiometry (CP), respectively. The co-deposition of Dy(III) and Sn(II) was analyzed, and four electrochemical signals related to Dy-Sn intermetallic compounds were observed. Galvanostatic electrolysis (GE) and potentiostatic electrolysis (PE) confirmed the feasibility of extracting Dy using liquid Sn electrode, with products characterized as DySn2 and (DySn3 + DySn2) by XRD and SEM-EDS.

Summary: In order to improve the accuracy of rural energy demand prediction, it is necessary to establish a simulation calculation model that is more in line with the actual rural energy endowment and development needs. Through the prediction and analysis of rural energy demand in the context of energy transition, the total rural energy demand can be predicted. The research shows that rural energy demand is influenced by multiple factors, and the traditional single model contains limited information, resulting in a large deviation between the prediction results and the actual situation, thus reducing the prediction accuracy.

Summary: In a directed graph G = (V, E), a feedback vertex set is a subset C that, when removed, makes the graph G acyclic. The feedback vertex set problem aims to find the minimum cardinality subset C*. This problem has various applications but is known to be NP-hard, posing computational challenges. To tackle this problem, the article proposes an iterated dynamic thresholding search algorithm that combines local optimization, dynamic thresholding search, and perturbation. Computational experiments on 101 benchmark graphs show that the algorithm outperforms state-of-the-art algorithms, achieving record-breaking best solutions for 24 graphs, equally best results for 75 graphs, and worse best results for only two graphs. The article also examines the impact of key components on the algorithm's performance.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
