A facet-dependent mechanism is demonstrated for highly-reversible and long-term stable ion insertion chemistry in TiS2 anode for the first time. The selective exposure of crystal planes is uncovered to effectively suppress the occurrence of hydrogen evolution reaction and transform the charge storage mechanism from the zinc ion insertion/ extraction...

An organic ionic plastic crystals characteristic salt with intrinsic poor interionic interaction is proposed, it decouples the salt dissociation of 1-ethyl-1-methylpyrrolidinium bis(fluorosulfonyl)imide (EMPFSI) from ion-solvation of 1-ethyl-1-methylpyrrolidinium cation (EMP+) and methyl acetate (MA), and enables an effective ion transfer and readily...

It has been observed that highly active electrocatalysts are frequently “disordered” or “amorphous” in nature. Is this structural property is a coincidence, or does it have an important function role?. Using metal oxides as an example, it is explored how amorphous and disordered metal oxides can react by fundamentally different pathways and their...

The study describes an efficient interfacial design strategy for solid-state polymer electrolytes and demonstrates the self-assembled ionic nanoclusters formed between metal ions and polyanions at the interfaces in lithium metal batteries can facilitate uniform lithium deposition and realize superfast charge-transfer kinetics by balancing the pre-exponential...

Thermoelectric technology enables direct energy conversion between heat and electricity. Topological semimetals, with unique band structures, hold great potential for transverse thermoelectrics owing to co-existence of high mobility electrons and holes. Herein, large transverse thermoelectric power factor is observed in NbAs2 topological semimetal...

This article reviews the electrosynthesis of valuable organic nitrogen compounds at ambient conditions from earth-abundant resources/wastes, such as CO2 and small nitrogenous molecules, via electrochemical C─N bond formation reactions, especially using carbon-based catalysts. The relevant electrochemical C─N bond formation mechanisms, the design principles...
