TL;DR: Electrochemical measurements show that VS2 nanosheet assemblies enable the rapid and durable storage of Li+, Na+ , or K+ ions, and the large reversible specific capacity and great cycling stability observed for both Na+ and K+ are extraordinary and superior to most existing electrode materials.

TL;DR: This study reports the remarkable promoting effect of Ni(OH)2 on Pd nanocrystals for electrocatalytic ethanol oxidation reaction in alkaline solution, which retains a mass-specific current even after 20 000 s of chronoamperometric testing, and can be regenerated via simple cyclic voltammetry cycles in clean KOH.

TL;DR: The facile solution synthesis of 2D PdAg alloy nanodendrites as a high-performance electrocatalyst is reported for ethanol electroxidation, and control experiments show that the improvement comes from the combined electronic and structural effects.

TL;DR: In this paper, a phase of molybdenum sulfide (amorphous chain-like MoS3) was used as an anode material of a Na3V2(PO4)3 cathode to achieve high capacity and cycling stability.

TL;DR: It is demonstrated that ultrasmall (∼5 nm) iron selenide (FeSe2) nanoparticles exhibited a remarkable activity for sodium-ion storage and exhibited a large specific capacity, high rate capability, and excellent cycling stability at both low and high current rates by virtue of their advantageous nanosizing effect.
