Synthesis of nanosized nickel sulfide in high-boiling solvent for all-solid-state lithium secondary batteries

Nickel Sulfide/Nitrogen‐Doped Graphene Composites: Phase‐Controlled Synthesis and High Performance Anode Materials for Lithium Ion Batteries

“…02‐1273). In fact, it is a general phenomenon that sulfides release some sulfur and change the phase under prolonged heating 26, 29, 42, 43. The evaporation of sulfur could be observed from TGA at ∼300 °C, where a mass loss occurred as shown in Figure S3.…”

“…Nowadays, metal sulfides have attracted tremendous attention in the field of LIBs due to their high theoretical capacities and low cost 9, 13–20. Among them, nickel sulfides are well known in technological applications, including magnetics, conductors, catalysts, phase changing materials and electrode materials for rechargeable LIBs 13, 21–31. Although a large number of nickel sulfides have been synthesized, such as NiS, NiS 2 , Ni 3+x S 2 , Ni 3 S 2 , Ni 3 S 4+x , Ni 3 S 4 , Ni 6 S 5 , Ni 7 S 6 and Ni 9 S 8 , only NiS and NiS 2 were studied extensively 25, 26, 29–31.…”

Ni 3 S 4 , with its high theoretical capacity (704.5 mAh/g), safety and cost effectiveness, is a promising candidate for anode material in LIBs.…”

Development of Sulfide Solid Electrolytes and Interface Formation Processes for Bulk-Type All-Solid-State Li and Na Batteries

“…Particle morphology and size can be controlled by choosing the reaction conditions and combinations of coordinating or non-coordinating solvents. NiS particles of 50 nm size were prepared using thermal decomposition of nickel acetylacetonate in a mixed solution of 1-dodecanethiol as a sulfur source and 1-octadecene as a non-coordinating solvent at 280°C for 5 h (Aso et al, 2011). The NiS nanoparticles are crystallized directly on a carbon fiber (VGCF) by adding VGCF to a liquid medium.…”

Synthesis and Growth Mechanism of White‐Fungus‐Like Nickel Sulfide Microspheres, and Their Application in Polymer Composites with Enhanced Microwave‐Absorption Properties

“…[14] In addition, nickel sulfides can form various phases, [15] such as NiS, Ni 3 + x S 2 , Ni 3 S 2 , Ni 7 S 6 , Ni 3 S 4 , and NiS 2 , and have multiple applications, including as photocatalysts for H 2 evolution, [16] possible transformation toughener, [17] cathode materials for rechargeable lithium batteries, [18] or as a highboiling solvent for all-solid-state lithium secondary batteries. [19] Furthermore, Du's group introduced the application of iron/ nickel sulfide filled carbon nanotubes and their microwave-absorbing properties, [20] with a maximum reflection loss of À29.58 dB. However, to the best of our knowledge, the microwave-absorbing properties of pure NiS x or its related inorganic-organic composite have not previously been reported.…”
