Layered double hydroxides (LDH) have been extensively investigated for charge storage, however, their development is hampered by the sluggish reaction dynamics. Herein, triggered mismatching integration of Mn sites, we configured wrinkled Mn/NiCo-LDH with strains and defects, where promoted mass & transport behaviors were realized. The well-tailored displays a capacity up to 518 C g-1 (1 A g-1), remarkable rate performance (78%@100 g-1) long cycle life (without decay after 10,000 cycles). We...
Localized "water-in-salt" (LWIS) electrolytes are promising candidates for the next generation of high-voltage aqueous with low viscosity/salt beyond high-salt electrolytes. An effective yet high-function diluent mainly determines properties LWIS electrolytes, being a key issue. Herein, donor number solvents is identified to serve as descriptor interaction intensity between and salts screen organic diluents having few impacts on solvation microenvironment intrinsic original electrolyte,...
Abstract As one of the key components supercapacitors, electrolyte is intensively investigated to promote fast development energy supply system under extremely cold conditions. However, high freezing point and sluggish ion transport kinetics for routine electrolytes hinder application supercapacitors at low temperatures. Resultantly, liquid should be oriented reduce point, accompanied by other superior characteristics, such as large ionic conductivity, viscosity outstanding chemical...
Abstract Defect engineering holds great promise for precise configuration of electrode materials dramatically enhanced performance in the field energy storage, but high energy/large time cost and lack control involved this process represent a serious limit to its use.

Pickering emulsion stabilized by solid nanoparticles provides a diverse solvent microenvironment and enables to promote the phase transfer of reaction substrates/products in catalytic reactions, but intrinsic role is still not clear. Herein, using benzyl alcohol (BA) as model reactant, we demonstrate nature water-promoted activity for oxidation over Pd/MgAl-LDO catalyst. Depending on water solvent, observe different reactivities regarding proportion system. Kinetic isotope effects confirm...
