In situ thermal exclusion induced Sb and Sb-doped SnO₂ nanoheterostructuring and its improvements in cycling stabilities and rate capacities for Na⁺ storage

Abstract

This work reports a novel in-situ thermal exclusion approach for the synthesis of carbon coated Sb and Sb-doped SnO2 hetero-nanoparticles (Sb-ATO hetero-NPs) deposited on the MWCNTs (C@Sb-ATO/MWCNTs) through the annealing...

Sb Doping and Amorphization Co‐Induced High Capacity and Excellent Durability of Tin Sulfide‐Based Anode for K‐Ion Batteries

“…Figure S1a (Supporting Information) shows a typical TEM image of the Sb─SnO 2 @CNTs, in which the growth of the small-sized Sb─SnO 2 on the CNTs can be clearly visualized. The XRD pattern of the Sb─SnO 2 @CNTs in Figure S2a (Supporting Information) shows the diffraction peaks corresponding to (110), (101), and (211) planes of the tetragonal structure Sb─SnO 2 [9] and (002) plane of the CNTs. It well demonstrates the formation of the Sb─SnO 2 @CNTs.…”

Seed-mediated formation of multiphase zero-valent Sb nanoparticles as alloying-type anodes for sodium-ion batteries with high capacity and ultra-long durability

“…Exploiting stable electrode materials with high sodium storage capacities is therefore of great importance. 9,10 According to the sodium storage mechanisms, materials applicable as anodes for SIBs can be generally classied into three categories, namely, intercalation, conversion, and alloying types. Compared with the intercalation-and conversion-type ones, the alloying-type materials show the advantages of high theoretical capacities, low sodiation potentials, and high electric conductivities.…”
