In this paper, experimental and computational results characterizing the preparation of binary nanoparticles by electrically exploding twin-wires composed aluminum silver elements are reported. Three kinds samples in parallel twisted arrangements exploded to collect nanoparticles. The mean diameter decreases with increasing energy deposited into per unit volume from 24.1 nm at 36.6 J/dm3 23.3 43.4 J/dm3. phase states derived different twin-wire configurations analyzed. surface scanning data arrangement reveal that weight percentage is consistent initial load counterpart. homogeneous elemental distribution separation observed collected A model based on molecular dynamics method constructed account for mixing nanoclusters elements. manifest temperature onset aggregation exerts a decisive influence state This paper helps understanding formation twin-wires.

Deciphering the Energy Storage Mechanism of Cos2 Nanowire Arrays for High-Energy Aqueous Copper-Ion Batteries

Опубликована: Янв. 1, 2024

Transition metal sulfide (TMs) offers ultra-high specific capacity through multi-electron transfer, showing promise for aqueous batteries. However, the poor cycling performance and uncleared energy storage mechanism is restricted from further development. Herein, CoS2 nanowire arrays grown on carbon cloth (CoS2/CC) are proposed as binder-free self-supporting electrodes copper-ion The clarified by a series of ex-situ tests: electrode reaction three-step CoS2→CuS→Cu7S4→Cu2S. Electrochemical results suggest that CoS2/CC cathode exhibits excellent long cycle stability (capacity retention 99.7% after 1000 cycles at 10 A g-1) along with high (762.3 mAhg-1 1 g-1). stable three-dimensional (3D) conductive structure can not only offer high-speed pathways to promote transfer electrons but also inhibit volume change. Meanwhile, surface-to-volume ratios improve wettability electrolyte redox reactions. Furthermore, an advanced Zn-CoS2/CC hybrid ion battery reveals density 724 Wh kg-1 output voltage 1.24 V, providing promising strategy establishment transition in high-energy
