Interfacial Bonding of Metal‐Sulfides with Double Carbon for Improving Reversibility of Advanced Alkali‐Ion Batteries

“…[ 8 ] For instances, through the cation‐exchange strategy, the SnSe@N‐doped carbon with SnC bonds were prepared, meaningfully verifying that the existing SnC rendered the lowering of ion‐diffusion and energy barriers, where its capacity would be kept about 300 mAh g −1 at 2.0 A g −1 . [ 9 ] Utilizing the high pressure and temperature, the bonds between Co 3 O 4 and graphene were established with the controlling content of CoOC, further demonstrating their great effect on electrochemical performance. [ 7b ] But, note that the complex preparing process and much chemical reagent using would render the disappointed prospect of its further applications, meanwhile hardly matching well with the purpose of “Green Chemistry.” [ 10 ]…”

Submicrospherical and Porous Bi2S3 Protected by Nitrogen‐Doped Carbon for Practical Anode Fabrication of Li‐Ion Batteries

“…The carbon coating layer can facilitate the electronic transport throughout the whole electrode, improving the utilization efficiency of active Bi 2 S 3 materials. The PDA‐derived porous and nitrogen‐doped carbon itself also can provide active sites for Li‐storage . In addition, such a homogeneous soft carbon coating layer can protect the inner Bi 2 S 3 core from structural pulverization and destruction during repeated cycling, and also benefits the stability of solid/electrolyte interphase (SEI) film formed on electrode surface .…”

“…The PDA-derived porous and nitrogen-doped carbon itself also can provide active sites for Listorage. [19,29,[36][37][38] In addition, such a homogeneous soft carbon coating layer can protect the inner Bi 2 S 3 core from structural pulverization and destruction during repeated cycling, and also benefits the stability of solid/electrolyte interphase (SEI) film formed on electrode surface. [35,39,40] The morphology of Bi 2 S 3 @NC electrode surface after 200 cycles was observed through SEM.…”

Self‐Supporting Electrode Composed of SnSe Nanosheets, Thermally Treated Protein, and Reduced Graphene Oxide with Enhanced Pseudocapacitance for Advanced Sodium‐Ion Batteries

“…To overcome these restrictions, extensive research suggests that it is an effective measure to fabricate SnSe and high conductive carbon composite materials . [30][31][32] Since carbonaceous materials such as reduced graphene oxide, carbon black and carbon nanotube not only can effectively buffer the mechanical stress during sodiation/desodiation process, but also enhance overall conductivity. Recently, Du et al [30] suggested that a simple ball-milling method proposed to prepare SnSe/reduced graphene oxide composites and the composite as anode exhibits a high rate capability of 260 mA h g À 1 at a current density of 10 A g À 1 , and superior cyclic performance (a capacity retention of 98 % over 120 cycles at a current density of 1 A g À 1 ).…”

“…However, the majority of them adopt traditional slurry-coating method to prepare electrode, which not only is tedious process, but also brings extra substances such as electrically insulating polymer binder (PVDF), conductive additive (Super P) and metallic current collector (cooper foil), resulting in increasing the total cost and depressing actually power density and energy density of batteries. [15][16][17][24][25][30][31][32][33] At present, self-supporting electrode composed of tin-based materials and carbon materials has been reported. [34][35] However, the structural stability of the composite needs to be further strengthened.…”
