Abstract Aqueous Zn‐metal batteries are the most promising system for large‐scale energy storage due to their high capacity, safety, and low cost. The anode, however, suffers from continuous parasitic reactions, random dendrite growth, sluggish kinetics in aqueous electrolytes. Herein, a donor number solvent, tetramethylurea (TMU), is introduced as electrolyte additive enable highly reversible where TMU can 1) preferentially adsorb on Zn surface inhibit corrosion suppress reaction, 2)...
Lithium metal batteries hold great promise for promoting energy density and operating at low temperatures, yet they still suffer from insufficient Li compatibility slow kinetic, especially ultra-low temperatures. Herein, we rationally design synthesize a new amphiphilic solvent, 1,1,2,2-tetrafluoro-3-methoxypropane, use in battery electrolytes. The lithiophilic segment is readily to solvate Li+ induce self-assembly of the electrolyte solution form peculiar core-shell-solvation structure....
Prognostic plays an important role in improving the reliability and durability performance of fuel cells (FCs); although it is hard to realize adaptive prognostic because complex degradation mechanisms influence operating conditions.

Then, virtual steady-state stack voltage formulated model space...
Proton exchange membrane fuel cell (PEMFC) degradation prediction is essential especially in transportation applications, since one of the major issues that hinder its worldwide commercialization represented by durability. However, due to complex physical phenomena inside cell, which are usually strongly inter-coupled, conventional semi-empirical model-based prognostics approach may fail predict aging under various operating conditions. In order improve accuracy, this paper proposed a...
Elevating the charging voltage could greatly promote energy density of lithium-ion batteries (LIBs) with LiNixMnyCozO2 cathodes, although challenges arise from severe parasitic reactions and rapid capacity decay at high voltage, especially for nickel-rich cathodes. Herein, by incorporating various useful functionalities into one single molecule, we rationally design synthesize a new class five-membered asymmetric cyclophosphamides as electrolyte additives to enable stable cycling...
Abstract The cavity-based X-ray free-electron laser (XFEL) has promise in producing fully coherent pulses with a bandwidth of few meV and very stable intensity, whereas the currently existing self-amplified spontaneous emission (SASE) XFEL is capable generating ultra-short chaotic spectra. In general, can provide spectral brightness three orders magnitude higher than that SASE mode, thereby opening new door for cutting-edge scientific research. With development superconducting MHz...
Metal–organic frameworks (MOFs) with high surface area, tunable porous structure, and versatile functionality hold great prospects for manipulating ion transport designing high-performance composite solid electrolytes (CSEs). However, the discontinuous poor mechanical support arising from randomly distributed MOF particles lead to insufficient ionic conductivity inferior strength. Herein, a highly efficient robust MOF-based 3D conducting network was rationally designed by in situ grown...
