Expandable graphite after PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron at 1000℃ heating to obtain expanded graphite. The SnS-SnS2-S/FLG composites were prepared with the molar ratio of Sn:S as 1:3 and the mass ratio of EG as 40wt% in stainless steel vial under Ar atmosphere for 20 hours, and the pellet ratio was 50:1. Comparative materials: SnS-SnS2-S was prepared after 20 h treatment; SnS/FLG was prepared after 20 h treatment. SnS2/FLG was prepared by treating SnS2 and EG (40wt%) for 20 h.
(SnS-SnS2)/FLG is prepared by extracting element S by treating CS2 aqueous solution (SNs-Sns2-s)/FLG at room temperature for 24h. (SnS -- SnS2 -- S)/FLG has the smallest grain size, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal effect is good. Raman spectroscopy showed that the layered structure EG was stripped to graphene by a synergistic action of rapid plasma heating and mechanical ball milling. The combustion peak of TG FLG is 500℃, which is significantly lower than that of EG at 720℃, indicating that FLG is very thin layered.
(SnS-SnS2-S)/FLG exhibits micron-level secondary particle structure composed of nano-level primary particles, which is beneficial to the treatment of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. The vibration density of micro-secondary particles is as high as 1.90g·cm-3, which is conducive to high volume capacity. The nanoscale primary particles consist of nancrystalline SnS, SnS2, and S phases. The in-situ reaction of SnS, SnS2, and S results in the formation of a high-proportion interface depicted by the green dashed line for ultrafast lithium storage. At the same time, the FLG matrix tightly supports the active nanoparticles to form the primary nanoparticles at the nanoscale, and provides an effective buffer layer for the active nanoparticles.
