Ammonium-ion batteries (AIBs) have recently attracted increasing attention in the field of aqueous batteries owing to their high safety and fast diffusion kinetics. The NH storage mechanism is quite different from that of spherical metal ions (e.g. Li , Na , K , Mg , and Zn ) because of the formation of hydrogen bonds between NH and host materials. Although many materials have been proposed as electrode materials for AIBs, their performances hardly meet the requirement of future electrochemical energy storage devices. It is thus urgent to design and exploit advanced materials for AIBs. This review highlights the state-of-the-art research on AIBs. The insights into the basic configuration, operating mechanism and recent progress of electrode materials and corresponding electrolytes for AIBs have been comprehensively outlined. The electrode materials are classified and compared according to different NH storage behaviour in the structure. The challenges, design strategies and perspectives are also discussed for the future development of AIBs.

Designing efficient catalysts for operating CO 2 electroreduction in membrane electrode assembly (MEA) faces significant obstacles. Herein, we propose an asymmetrically coordinated Ni single-atom catalyst featuring axial Br coordination at NiN 4 Br sites anchoring onto hollow Br/N co-doped carbon nanocages, achieved through a NaBr-assisted confined-pyrolysis strategy. The Ni-NBr-C catalyst exhibits a high CO Faradaic efficiency (FE CO >97 %) over the current density range of 50 to 350 mA cm −2 in the MEA device. Furthermore, Ni-NBr-C shows a stable cell voltage of 2.66±0.2 V while delivering a large current density of 350 mA cm −2 over an 85-hour long-term operation, demonstrating its potential for industrial-scale applications. advanced characterization techniques and theoretical calculations reveal that the coordination and doping of Br not only enhance the intrinsic activity but also highlight that the unique pore structure improves mass transfer efficiency.

The discovery and continual development of lithium-ion batteries (LIBs) are the keys to enabling the global implementation of smart devices and electric vehicles (EVs). On the cathode side, transitioning away from the highly priced cobalt has been a prerequisite for the grant mission of achieving complete vehicle electrification yet a major challenge for the battery research communities. In this perspective, from the aspects of material design and optimization, the current status and future contour of cathodes are sketched in pursuing the ever-increasing threshold of high-performance and low-cost LIBs.

Conversion-type anode materials with high theoretical capacities play a pivotal role in developing future aqueous rechargeable batteries (ARBs). However, their sustainable applications have long been impeded by the poor cycling stability and sluggish redox kinetics. Here we show that confining conversion chemistry in intercalation host could overcome the above challenges. Using sodium titanates as a model intercalation host, an integrated layered anode material of iron oxide hydroxide-pillared titanate (FeNTO) is demonstrated. The conversion reaction is spatially and kinetically confined within sub-nano interlayer, enabling superlow redox polarization (ca. 4–6 times reduced), ultralong lifespan (up to 8700 cycles) and excellent rate performance. Notably, the charge compensation of interlayer via universal cation intercalation into host endows FeNTO with the capability of operating well in a broad range of aqueous electrolytes (Li + , Na + , K + , Mg 2+ , Ca 2+ , etc.). We further demonstrate the large-scale synthesis of FeNTO thin film and powder, and rational design of quasi-solid-state high-voltage ARB pouch cells powering wearable electronics against extreme mechanical abuse. This work demonstrates a powerful confinement means to access disruptive electrode materials for next-generation energy devices.

Novel CoCrFeNiTiAlx(x:molar ratio, other elements are equimolar) high-entropy alloys were prepared by vacuum arc melting and these alloys were subsequently annealed at 1000 °C for 2 h. The annealing effects on structure and mechanical properties were investigated. Compared with the as-cast alloys, there are many complex intermetallic phases precipitated from the solid solution matrix in the as-annealed alloys with Al content lower than Al1.0. Only simple BCC solid solution structure appears in the as-annealed Al1.5 and Al2.0 alloys. This kind of alloys exhibit high resistance to anneal softening. Most as-annealed alloys possess even higher Visker hardness than the as-cast ones. The as-annealed Al0.5 alloys shows the highest compressive strength while the Al0 alloy exhibits the best ductility, which is about 2.6 GPa and 13%, respectively. The CoCrFeNiTiAlx high-entropy alloys possess integrated high temperature mechanical property as well.

A novel type of covalent organic frameworks has been developed by assembling definite cobalt-nitrogen-carbon configurations onto carbon nanotubes using linkers that have varying electronic effects. This innovative approach has resulted in an efficient electrocatalyst for oxygen reduction, which is understood by a combination of in situ spectroelectrochemistry and the bond order theorem. The strong interaction between the electron-donating carbon nanotubes and the electron-accepting linker mitigates the trend of charge loss at cobalt sites, while inducing the generation of high spin state. This enhances the adsorption strength and electron transfer between the cobalt center and reactants/intermediates, leading to an improved oxygen reduction capability. This work not only presents an effective strategy for developing efficient non-noble metal electrocatalysts through reticular chemistry, but also provides valuable insights into regulating the electronic configuration and charge behavior of active sites in designing high-performance electrocatalysts.

Over the last decade, significant effort has been devoted to the applications of hierarchically structured porous materials owing to their outstanding properties such as high surface area, excellent accessibility to active sites, and enhanced mass transport and diffusion. The hierarchy of porosity, structural, morphological and component levels in these materials is key for their high performance in all kinds of applications. The introduction of hierarchical porosity into materials has led to a significant improvement in the performance of materials. Herein, recent progress in the applications of hierarchically structured porous materials from energy conversion and storage, catalysis, photocatalysis, adsorption, separation, and sensing to biomedicine is reviewed. Their potential future applications are also highlighted. We particularly dwell on the relationship between hierarchically porous structures and properties, with examples of each type of hierarchically structured porous material according to its chemical composition and physical characteristics. The present review aims to open up a new avenue to guide the readers to quickly obtain in-depth knowledge of applications of hierarchically porous materials and to have a good idea about selecting and designing suitable hierarchically porous materials for a specific application. In addition to focusing on the applications of hierarchically porous materials, this comprehensive review could stimulate researchers to synthesize new advanced hierarchically porous solids.

Continuous hydrogen-bond-network in aqueous electrolytes can lead to uncontrollable hydrogen transfer, and combining the interfacial parasitic electron consumption cause the side reaction in aqueous zinc metal batteries (AZMBs). Herein, hydrogen/electron amphiphilic bi-functional 1,5-Pentanediol (PD) molecule was introduced to stabilize the electrode/electrolyte interface. Stronger proton affinity of -OH in PD can break bulk-H 2 O hydrogen-bond-network to inhibit the activity of water, and electron affinity can enhance electron acceptation capability, which ensures that PD is preferentially bound to electrode material over H 2 O. Besides, the participation of PD in the Zn 2+ solvation structure reduces water content at the solid–liquid interface and promotes uniform deposition process by optimizing Zn 2+ de-solvation energy. Accordingly, dense and vertical zinc texture based on intrinsic steric hindrance effect of PD and formed SEI protective layer to induce stable Zinc anode-electrolyte interface. Moreover, an organic–inorganic shielding water layer was formed at the cathode side to suppress vanadium dissolution in vanadium Oxide. Consequently, Zn//Zn symmetric cell could cycle for more than 5600 hours at 1 mAh cm −2 @1 mA cm −2 (more than 250 hours at 50 °C). Besides, the VO 2 and I 2 cathode all achieved stable cycling performance and former pouch cell could reach average capacity of 0.13 Ah.

In den letzten Jahren haben zahlreiche Studien gezeigt, dass die Effizienz der Photokatalysatoren für die Produktion von Solarbrennstoffen deutlich gesteigert werden kann, wenn man Graphen verwendet, das eine besondere konjugierte 2D‐Struktur und spezielle elektronischen Eigenschaften besitzt. Dieser Aufsatz gibt einen Überblick über jüngste Fortschritte bei der Anwendung von Photokatalysatoren auf Graphenbasis für die Produktion von Solarbrennstoffen einschließlich der CO 2 ‐Reduktion zu Kohlenwasserstoffen und der H 2 ‐Erzeugung mittels Wasserspaltung. Die Grundlagen der Wasserspaltung und der CO 2 ‐Reduktion werden kurz dargestellt. Die für die Verbesserung der photokatalytischen Leistung relevanten Funktionen des Graphens werden diskutiert. Mit Blick auf bestehende Herausforderungen und Möglichkeiten auf diesem vielversprechenden Gebiet werden schließlich mögliche Perspektiven erörtert.
