When analyzing recrystallization kinetics data, it is extremely important to use a model, which has appropriate assumptions for nucleation and growth, including spatial distribution of nuclei, nucleation rate, growth rate, and directionality. In the present work, we reveal how advanced microstructural path modeling (MPM) can successfully fit kinetics data for the complex recrystallization of two different industrial aluminum alloys. Simpler models have failed to fit the data over the entire recrystallization period. The new model allows for spatially clustered nucleation and for different growth rates in different sample directions, whereby the grains evolve with an aspect ratio different from 1. Based on the MPM analysis, the specific nucleation and growth parameters as well as the recrystallized grain sizes are deduced, and the recrystallization characteristics of the two alloys are compared. The work demonstrates the power of quantitative metallography and the wealth of recrystallization information that may be obtained from MPM modeling of such stereological data.

According to the International Energy Agency (IEA) strategy, water electrolysis will be a second priority for hydrogen production by 2030, which can support sustainable development goals (SDGs). However, for the large-scale application, especially seawater electrolysis at a high current density, cost and durability of the electrocatalytic system need to be taken into account. Herein, fundamental mechanisms of seawater electrolysis in a wide range of pH values, potential electrocatalysts for overall water splitting, recent progress on synthesis electrocatalysts and basic principles for the evaluation of electrocatalysts are reviewed. Subsequently, critical parameters and issues for scaling-up of seawater electrolyzers are critically discussed. Finally, future prospects for completing sustainable hydrogen production from seawater for sustainable development are outlooked. It is anticipated to offer guidelines for the design and production of innovative electrocatalysts with high electrocatalytic activity and durability for the industrial scale application.

Solid-state lithium metal batteries (SLMBs) based on solid polymer electrolytes (SPEs) are a promising option for next-generation energy storage systems owing to their enhanced safety and energy density. However, the unstable interfaces resulting from continuous side reactions between electrodes and SPEs during cycling have hindered the practical application of SLMBs. In this review, we first provide an overview of the development and fundamentals of SPEs. Subsequently, the interface issues, factors influencing interface stability, and strategies to stabilize and enhance the compatibilities of the SPEs/electrodes interface are summarized. Finally, we propose perspectives on improving interface contact and stability through effective strategies for practical high-energy SLMBs. This review aims to deepen the understanding of interfacial issues between SPEs and electrodes and provide specific solutions to improve the electrochemical performances of SLMBs.

Two-dimensional (2D) transition metal borides (MBenes) as an analog to 2D transition metal carbides/nitrides (MXenes) have been considered promising platform materials for exploring their physical and chemical properties, due to their tunable composition, excellent stability, and good conductivity. Lots of theoretical studies have predicted possible mechanical, magnetic, and catalytic properties of MBenes, which inspired their research in energy storage and conversion applications. However, a detailed review focusing on the synthesis of high-quality MBene nanosheets and their energy-related applications is not available. In this review, MBene with different structures and the latest developments in synthesizing high-quality MBene nanosheets from top-down exfoliation and down-top chemical vapor deposition are first summarized. Then, the basic properties of MBene are investigated, including mechanical properties, metallicity, and magnetism. Next, their key applications such as hydrogen production, ammonia production, and energy storage are elaborately discussed. Finally, the future perspectives and key challenges of MBenes's synthesis and applications are briefly provided.

Over the past three decades, lithium-based batteries have greatly influenced our daily lives. However, their limited energy density poses challenges in meeting growing demand. To increase energy density, lithium metal anode is considered critical. This review systematically examines the history of lithium metal anode development, highlights notable advances in fundamental understandings, materials design, and characterization techniques. Forthcoming opportunities are discussed to promote the practical applications of lithium metal anodes.

The remarkable market growth of lithium-ion batteries (LIBs) for various applications has been witnessed in the past two decades. However, as a retirement wave of more and more LIBs approaches, the disposed end-of-life batteries represent a growing hazard to ecosystem and human health. Recycling valuable metals from those spent LIBs still remain challenging because the current conventional metallurgical recycling processes involve the emission of toxic gas and waste chemicals as well as intensive energy consumption. These processes are not considered as green recycling approaches that contradict with the principles of carbon neutrality and circular economy embraced by the world. Hence, implementing green and sustainable recycling technologies of spent LIBs, especially for cathode materials, is an urgent need. This review provides a comprehensive understanding and critical evaluation of traditional pyrometallurgy, hydrometallurgy, and state-of-the-art direct recycling for recovering valuable metal materials from the spent LIB cathode. The fundamentals, methods, efficiencies, and feasibility of the three recycling approaches are also assessed. In addition, the recent progress for green innovation of hydrometallurgical and direct recycling processes as well as the potential research tendency for spent LIBs are discussed.
