Lithium-selenium (Li-Se) batteries have attracted increasing attention as one of the next-generation battery systems due to much higher electronic conductivity and comparable volumetric capacity of Se compared to the popular sulfur cathode. However, its practical application still faces great challenges, especially the rapid capacity decay triggered by the loss of active Se species. A comprehensive review to uncover the in-depth failure mechanism and provide targeted solutions to promote the stable operation of Li-Se batteries is urgently needed. This review systematically summarizes the strategies in the new perspective, focusing on the optimization of Se utilization in Li-Se batteries by keeping a high Se maintenance in the cathode and accelerating the electrochemical kinetics of lithium polyselenides (LiPSe) conversion. On the basis of structural design and Li 2 Se active material introduction to accommodate volume expansion, blocking shuttle transport of LiPSe by physical/chemical adsorption, bonding Se with polymers or cathode electrolyte interphase (CEI) construction, and catalytic design to accelerate the conversion of LiPSe, different strategies for improving the utilization of Se have been evaluated and discussed. To address the inevitable loss of Se, prospects on inactive Se reactivation and Li protection are detailedly proposed and analyzed referring to the chemistry and corrosion science. Additionally, the perspectives on the future design and comprehensive parameter evaluations for the optimization of Li-Se batteries are recommended. This review comprehensively explains the causes and solutions of capacity fading and provides potential efforts for lifespan expansion of batteries, shedding light on the future development of Li-Se batteries.

With the increasing penetration of clean energy in power grid, lead-acid battery (LAB), as a mature, cheap and safe energy storage technology, has been widely used in load dispatching and energy trading. Because of the long-term partial state of charge operation in the LAB energy storage system, the irreversible sulfation problem seriously restricts the efficient and safe operation of the system. A proactive maintenance concept in life cycle based on the capacitive nature of the sulfation is introduced in this paper to determine the resonance frequency of sulfation LAB as the diagnostic support. The resonance excitation achieves an average of 23% impedance restoration on tested LABs within 2 hours. Furthermore, based on the life cycle theory, it is estimated that the proposed proactive maintenance concept can save 3.228 tons of equivalent lead leakage for a 500kW LAB energy storage system in one year. The proactive maintenance concept in life cycle proposed in this paper provides an important technical support for the development of efficient, economical and environmental friendly LAB energy storage system, and provides a new way for the sustainable development of LAB industry. © 2021 IEEE.

Molecular dynamics simulations can explore the characteristics and evolution of microstructures in alloys outside of experiments, with reliability and accuracy guaranteed by the interatomic potentials employed. Machine learning potential (MLP) is widely used for its accuracy close to first-principles calculations. When developing an MLP, the construction of the training dataset is crucial, determining the accuracy and generalization of the MLP. In this work, a Monte-Carlo-like (MCL) strategy is proposed to construct training datasets for developing MLPs of alloys, which is characterized by the efficient consideration of element distributions in alloys. As an example, a training dataset for the equimolar NbTiZrHf alloy is constructed based on the MCL strategy, and the corresponding MLP is developed subsequently. By comparing with two traditional strategies, it is found that the training dataset constructed based on the MCL strategy has greater dispersion, and the corresponding MLP has better prediction performance. In addition, a hybrid molecular statics and Monte Carlo simulation with the MCL-based MLP is performed to optimize the element distribution of the equimolar NbTiZrHf alloy, and segregation and short-range ordered structures are observed in the final configuration, which is consistent with the experimental results reported in the literature. The MCL strategy proposed in this work can provide a fast solution for considering the element distribution when constructing training datasets for developing MLPs of alloys.

Calcination is a critical technique for preparing diatomite filter aids, which enhances their permeability and whiteness. However, calcination is accompanied by a severe reduction in the adsorption capacity of calcined diatomite (C-D). Applications such as high-end filter aids and fine adsorbents typically require C-D with high adsorption performance. So, it is imperative to modify and design C-D for superior adsorption performance while maintaining its permeability. In this study, C-D was modified using sodium hydroxide (NaOH) and magnesium chloride (MgCl2) via a hydrothermal process, and the mechanism of modification was investigated. The resulting Zeolite-P/C-D (modified calcined diatomite, M-D) exhibited not only a high adsorption capacity, but also displayed admissible permeability. Compared with C-D, the adsorption capacity of M-D had increased by dozens of times, and the permeability of M-D remained about 1 darcy. XRD, SEM, TEM, and FTIR analyses revealed the synthesis of Zeolite-P on the surface of C-D. The structure and morphology characteristics of Zeolite-P could be controlled by adjusting the amount of MgCl2, resulting in M-D samples with varying adsorption capacities and permeabilities. This study presents a simple and environmentally friendly approach for modifying C-D, thereby improving the adsorption performance of diatomite filter aids. It paves a way for the comprehensive and efficient utilization of diatomite resources. © 2023, The Authors. All rights reserved.

A novel solid-gas reaction preparation technology was used to adjust the composition and microstructure of the composite crystal materials by changing the preparation parameters. Compared with the commonly used sol-gel method, acid base neutralization sedimentation method, hydrothermal method, and gas phase deposition method, the technology was relatively simplified and the elemental composition was controllable, without the use of openings and additives. A kind of multi-element composite porous metal oxide was obtained by pre-intercalation and decarburization. In order to increase the porosity of MoO3 material and promote the adsorption and diffusion of reactant molecules, the microstructure of MoO3 was studied. The preparation process of porous molybdenum trioxide by solid gas combination process was discussed, which provides an innovative idea for the design and preparation of new materials with a large specific surface area and other desirable properties.

Thermoelectric semiconductors are crucial for many critical applications, but are also universally fragile, which greatly limits the development of room temperature flexible thermoelectric devices. Herein, an extraordinary deformability at room temperature and high thermoelectric performance are simultaneously realized in wide composition of Ag2Te1-xSex (x = 0-0.2) compounds with monoclinic structure. An average compressive strain rate of 24% at room temperature is attained for the pristine Ag2Te compound. Moreover, a tensile strain rate of 43% is measured at room temperature using the in-situ transmission electron microscopy. First Principles calculations and in-situ transmission electron microscope tensile test results indicate that the Ag2Te compound is inclined to slip along the (-102) [010] plane under external forces due to a larger ratio between the cleavage energy (Ec) and the slip energy barrier. The slipping process generates high concentrations of dislocations, deformations, and amorphous structures, which together dissipate the externally applied load energy, yielding superior deformability. Meanwhile, the maximum dimensionless figure of merit ZT of 0.61 is obtained at 380 K. This study demonstrates that Ag2Te-based compounds are promising for the fabrication of flexible thermoelectric devices in applications, such as wearable, room temperature electronic gadgets. © 2023, The Authors.
