Phosphorus doping induced the co-construction of sulfur vacancies and heterojunctions in tin disulfide as a durable anode for lithium/sodium-ion batteries

Abstract

The reasonable design of electrode materials with heterojunction and vacancy is a promising strategy to elevate its electrochemical performances. Herein, tin-based sulfide composites with heterojunction and sulfur vacancy encapsulated by...

Synthesis of Nanostructured Bismuth Sulfide with Controllable Morphology for Advanced Lithium/Sodium-Ion Storage

“…12−15 Therefore, it is urgent to explore potential anode materials for LIBs and SIBs that combine long cycle life and high capacity at the same time. Metal sulfides, for example, Co 1−x S, 16 Ni 2 S 3 , 17 VS 4 , 18 SnS, 19,20 SnS 2 , 21,22 MoS 2 , 23,24 ZnS, 25 and Fe 7 S 8 , 26 with the advantages of low cost, considerable electrical conductivity, and excellent capacity, are potential anode materials in the fields of LIBs and SIBs. 27,28 Specifically, Bi 2 S 3 as one of the chalcogen-based materials with a narrow direct band gap of 1.3 eV 29 and a laminar structure 30 shows potential applications in many fields such as photoelectricity, 31 biology, 32 photocatalysis, 33 and electrocatalysis.…”

Delicate fabrication of ZnO/ZnCo2O4heterojunction HoMSs as anodes for lithium-ion batteries with high rate capability

“…76–79 Thirdly, the construction of heterojunctions fosters fast electron diffusion at the interface. 61 As shown in Fig. 5a–e, the crystal structure of the ZnO/ZnCo 2 O 4 heterojunction was simulated by DFT (density functional theory), in which the (001) lattice of ZnO matched with the (001) lattice of ZnCo 2 O 4 perfectly.…”

“…3f. Furthermore, the construction of heterojunctions fosters fast electron diffusion at the interface; 60,61 as shown in Fig. 3g, ZnO/ZnCo 2 O 4 Q-HoMS-2/1 possessed the minimum interface impedance, thus demonstrating excellent rate capability and cycling stability.…”

Completely suppressed high-voltage phase transition of P2/O3-Na0.7Li0.1Ni0.1Fe0.2Mn0.6O2viaLi/Ni co-doping for sodium storage

“…[1][2][3][4][5][6][7] In general, the energy density and cycling life of SIBs are highly dependent on cathode materials. [8][9][10][11] Among various cathode materials, P2-type Fe, Mn-based layered oxides for SIBs have been attractive owing to the huge abundance, eco-friendliness, and low price of Fe and Mn. [12][13][14][15] In particular, P2-Na 2/3 Fe 1/2 Mn 1/2 O 2 possesses a high capacity of 190 mA h g −1 within the potential range from 1.5 to 4.3 V, benefitting from those two redox couples of Fe 3+ /Fe 4+ and Mn 3+ /Mn 4+ .…”
