Lithium metal anode(LMA) is a promising candidate for achieving next-generation high-energy-density batteries due to its ultrahigh theoretical capacity and most negative electrochemical potential. However, the practical application of lithium metal battery(LMB) is largely retarded by the instable interfaces, uncontrolled dendrites, and rapid capacity deterioration. Herein, we present a comprehensive overview towards the working principles and inherent challenges of LMAs. Firstly, we diligently summarize the intrinsic mechanism of Li stripping and plating process. The recent advances in atomic and mesoscale simulations which are crucial in guiding mechanism study and material design are also summarized. Furthermore, the advanced engineering strategies which have been proved effective in protecting LMAs are systematically reviewed, including electrolyte optimization, artificial interface, composite/alloy anodes and so on. Finally, we highlight the current limitations and promising research directions of LMAs. This review sheds new lights on deeply understanding the intrinsic mechanism of LMAs, and calls for more endeavors to realize practical Li metal batteries.

Semiconductors are promising in photoelectric and thermoelectric devices, for which the thermal transport properties are of particular interest. However, they have not been fully understood, especially when crystalline imperfections are present. Here, using cadmium telluride (CdTe) as an example, we illustrate how grain boundaries (GBs) affect the thermal transport properties of semiconductors. We develop a machine-learning force field from density functional theory calculations for predicting the lattice thermal conductivity (LTC) via equilibrium molecular dynamics simulations. The LTC of crystalline CdTe decreases with the relationship of κL~1/T in the simulation temperature range of 300 – 900 K, in which the isotropic LTC decreases from 3.34 to 0.23 W/ (m⋅K) due to the enhanced anharmonicity. More important, after introducing GBs, the LTC is suppressed in all directions, especially in the direction normal to the GB planes. More severe LTC suppression occurs in CdTe with Σ9 GB than that with Σ3 GB at 300 K, decreasing by 92.8% and 61.4% along the direction normal to the GB planes compared to the isotropic LTC of the crystalline CdTe, respectively. The decreased LTC is consistent with the weaker bonding near GB planes and lower shear modulus of the defective material. The analyses of the phonon dispersion curves, vibrational density of states, and phonon participation ratio indicate that the decreased LTC mainly arises from phonon scattering at GBs. Overall, our work highlights that GBs can greatly influence the LTC of semiconductors, thus providing a promising approach for thermal property design.

Body-centred cubic(BCC) metals are known to have unstable intrinsic stacking faults and high resistance to deformation twinning, which can strongly influence their twinning behaviour. Though twinning mechanisms of BCC metals have been investigated for more than 60 years, the atomistic level dynamics of twinning remains under debate, especially regarding its impact on competition between twinning and slip. Here, we investigate the atomistic level dynamics of twinning in BCC tungsten(W) nanowires using in situ nanomechanical testing. Quantitative experimental studies directly visualize that deformation twins in W nanowires have a minimum size of six-layers and grow in increments of approximately three-layers at a time, in contrast to the layer-by-layer growth of deformation twins in face-centred cubic metals. These unique twinning dynamics induces a strong competition with ordinary dislocation slip,as exhibited by a size-dependent dislocation-to-twin transition in W nanowires, with a transition size of ~40 nm. Our work provides physical insight into the dynamics of twinning at the atomic level, as well as a size-dependent dislocation-twinning competition, which have important implications for the plastic deformation in a broad class of BCC metals and alloys.

Lithium-ion batteries have revolutionized portable electronics and electric transportation, but their longevity and performance continue to be the focus of research. Single crystal nickel manganese cobalt (SC-NMC) cathodes are emerging materials for advancing lithium-ion battery technology. However, harnessing their potential requires comprehending the degradation mechanisms which occur during cycling. This review presents an extensive analysis of the intricate degradation processes affecting them. We explore the structural transformations, surface layer formation, and lithium loss mechanisms that govern the capacity fade and voltage decay observed in these cathode materials. By examining the latest developments in diagnostic techniques and characterization methods, we examine the tools available for studying degradation phenomena. Furthermore, mitigation strategies to enhance the resilience of NMC cathodes are explored, elucidating material modifications and protective coatings. Understanding this is pivotal for designing more robust lithium-ion batteries. This review identifies critical research gaps, offering a roadmap for advancements in energy storage. © 2023 IEEE.

In the last decades, corrosion control of metals and their alloys has been of environmental, aesthetic, economic,and technical importance. Ecologically acceptable, environment-friendly, and readily available corrosion inhibitors are one of the best options for protecting metals against corrosion. In this regard, use of polymers for inhibiting metallic corrosion is an authentic and acceptable practice, with a low environmental threat. Polymers may be used as composites, blends, or isolation for optimal inhibitory effects. Inhibition efficiencies of corrosion inhibitors were determined using mass loss, electrochemical impedance spectroscopy, potentiodynamic polarization techniques, etc. The present study gives the idea about natural, synthetic, and conducting polymers and their utilization for corrosion inhibition applications. Effects of halide ions as additives or surfactants on their anticorrosion performances are also discussed. Polymeric materials as coatings are reviewed to align with recent research interests, such as cost-effectiveness, environment friendliness, and self-healing products, which are more convenient to synthesize and use in future applications.
