Boosting the sodium storage of the 1T/2H MoS₂@SnO₂ heterostructure via a fast surface redox reaction

Abstract

Ultrasmall SnO2 nanoparticles distributed on dual phase MoS2 sheets boost the Na+ storage kinetics via a fast surface redox reaction.

Encapsulation of 2D MoS2 nanosheets into 1D carbon nanobelts as anodes with enhanced lithium/sodium storage properties

“…The decrease in R ct can be attributed to the process of activation after cycling. Furthermore, based on eqn (5) and (6), the diffusion coefficient of Li + ( D Li+ ) can be obtained: 66,69,70 D = R 2 T 2 /2 n 4 F 4 σ w 2 A 2 C 2 Z ′ = R + σ w ω -1/2 where R and T represent the gas constant and temperature, respectively. A , C , n , F and σ w are ascribed to the area of the electrode, the concentration of Li + , the number of electrons, Faraday constant, and Warburg coefficient, respectively.…”

Realizing the high energy density and flexibility of a fabric electrode through hierarchical structure design

“…29 As a result, the internal stress can be efficiently lowered by the interlayer slipping of NiPS 3 , similar to the phenomenon observed in MoS 2 . 39,40 The proposed toughening mechanism of the NiPS 3 /NCNFs is illustrated in Fig. 5f.…”

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

“…Remarkably, the rate capacities of C@Sb-ATO/MWCNTs are also higher than those of most SnO 2 -based and many other anodes reported previously (Table S2 †). [32][33][34] Fig. 4a and b show the SEM images of the C@Sb-ATO/MWCNT anode with the binder and carbon black before and aer 250 cycles.…”
