Abstract Spinel LiMn 2 O 4 , whose electrochemical activity was first reported by Prof. John B. Goodenough's group at Oxford in 1983, is an important cathode material for lithium‐ion batteries that has attracted continuous academic and industrial interest. It cheap environmentally friendly, excellent rate performance with 3D Li + diffusion channels. However, it suffers from severe degradation, especially under extreme voltages during high‐temperature operation. Here, the current...
A new “full fluorosulfonyl” (FFS) electrolyte is developed for highly reversible 4 V class lithium-metal batteries (LMBs).
An integral LiMn<sub>1.5</sub>Ni<sub>0.5</sub>O<sub>4</sub> shell completely wets ∼10 μm LiCoO<sub>2</sub> single crystals to cut off global oxygen migration and enables >4.6 V cycling.
Abstract Solar‐driven interfacial evaporation (SDIE) is a highly promising approach to achieve sustainable desalination and tackle the global freshwater crisis. Despite advancements in this field, achieving balanced thermal localization salt resistance remains challenge. Herein, study presents 3D hierarchical porous ceramic platform for SDIE applications. The utilized alumina foam ceramics (AFCs) exhibit remarkable corrosion chemical stability, ensuring prolonged operational lifespan...
Aqueous zinc-ion batteries (ZIBs) are promising energy storage solutions with low cost and superior safety, but they suffer from chemical electrochemical degradations closely related to the electrolyte. Here, a new zinc salt design drop-in solution for long cycle-life aqueous ZIBs reported. The Zn(BBI)2 rationally designed anion group, N-(benzenesulfonyl)benzenesulfonamide (BBI- ), has special amphiphilic molecular structure, which combines benefits of hydrophilic hydrophobic groups properly...
Aqueous zinc-ion batteries are promising due to inherent safety, low cost, toxicity, and high volumetric capacity. However, issues of dendrites side reactions between zinc metal anode the electrolyte need be solved for extended storage cycle life. Here, we proposed that an additive with intermediate chelation strength ion-strong enough exclude water molecules from metal-electrolyte interface not too strong cause a significant energy barrier ion dissociation-can benefit electrochemical...
Abstract A practical solution is presented to increase the stability of 4.45 V LiCoO 2 via high‐temperature Ni doping, without adding any extra synthesis step or cost. How a putative uniform bulk doping with highly soluble elements can profoundly modify surface chemistry and structural identified from systematic chemical microstructural analyses. This modification has an electronic origin, where surface‐oxygen‐loss induced Co reduction that favors tetrahedral site causes damaging spinel...
Studying on the anode materials with high energy densities for next-generation lithium-ion batteries (LIBs) is key wide application electrochemical storage devices. Ti-based compounds as promising are known their outstanding high-rate capacity and cycling stability well improved safety over graphite. However, still suffer from low capacity, thus largely limiting commercialized application. Here, we present an overview of recent development in LIBs, special emphasis placed enhancement by...

In this work, the effect electrical hydrogen reduction on grain growth behavior doped zirconia ceria has been investigated. Faster observed under reducing conditions in all cases. results firmly establish that a depressed local oxygen potential can enhance cation fluorite‐structured oxide ceramics. Meanwhile, large current generate sharp, spatially varied profile, creating graded microstructure...
Abstract Li‐rich metal oxide (LXMO) cathodes have attracted intense interest for rechargeable batteries because of their high capacity above 250 mAh g −1 . However, the side effects hybrid anion and cation redox (HACR) reactions, such as oxygen release phase collapse that result from global migration (GOM), prohibited commercialization LXMO. GOM not only destabilizes sublattice in cycling, aggravating well‐known voltage fading, but also intensifies electrolyte decomposition Mn dissolution,...
Proton conduction underlies many important electrochemical technologies. A family of new proton electrolytes is reported: acid-in-clay electrolyte (AiCE) prepared by integrating fast carriers in a natural phyllosilicate clay network, which can be made into thin-film (tens micrometers) fluid-impervious membranes.
