Embodiment 1
[0016] A kind of preparation method of the graphite intercalation compound of metal salt as intercalation agent, comprises: 1g particle size is the natural graphite of 10 μ m after drying 4h at 120 ℃, after adding 3.4g anhydrous ferric chloride rapidly, then stirring and mixing in the air, Then vacuum-dried at 120° C. for 1 hour and then transferred to a reaction kettle. After sealing the reaction kettle in the air, it was placed in a heating furnace and heated to 450° C. and kept for 48 hours. The obtained product was washed with deionized water, alcohol and acetone and dried at 80 °C for 12 h to obtain a first-order FeCl 3 -graphite intercalation compound (as attached figure 1 Shown), the sample is named FG-1 (F ferric chloride, -2 first order). Take 0.3g of the FG-1 prepared above in CS 2 Heating it to 550°C at a heating rate of 5°C / min in the mixture with nitrogen gas and holding it for 2 hours to prepare a graphite intercalation compound intercalated with iron sulfide, ...
Embodiment 2
[0020] Dry 1g of natural graphite with a particle size of 10μm at 100°C for 4h, then quickly add 1.7g of anhydrous ferric chloride, stir and mix in the air, then dry it in vacuum at 100°C for 1h, and then transfer it to the reactor. After the gloves are sealed in the air, place them in a heating furnace and heat them to 450°C and keep them warm for 24 hours. The obtained product was washed with deionized water, alcohol and acetone and dried at 80 °C for 12 h to obtain the second-order FeCl 3 - Graphite interlayer compound, the sample is named FG-2 (F ferric chloride, -2 second order);
[0021] Take 0.5g of FG-2 and treat it under the mixed gas of hydrogen and argon at 450°C for 4 hours to obtain RFG-2 (R hydrogen reduction). Take 0.3g of RFG-2 and 0.6g of elemental sulfur in the air and mix them in the reaction kettle. Heat to 155°C and keep it for 12h, then raise the temperature to 350°C and keep it for 2h to make sulfur react with elemental metal to form sulfide. Finally, ...
Embodiment 3
[0023] Dry 1g of natural graphite with a particle size of 10μm at 120°C for 4h, then quickly add 6.8g of anhydrous ferric chloride, stir and mix in the air, then dry it in vacuum at 120°C for 1h, and then transfer it to the reactor. After sealing in the air, place it in a heating furnace and heat it to 450°C and keep it warm for 12 hours. The obtained product was washed with deionized water, alcohol and acetone, dried at 80°C for 12 hours, and collected for later use. The sample was named FG-1 (F ferric chloride, -1 first order). Take 0.3g of the above-prepared FNG-1 and heat it to 550°C at a heating rate of 5°C / min in a mixed atmosphere of hydrogen sulfide and nitrogen, and keep it warm for 2 hours to prepare an iron sulfide intercalated graphite intercalation compound.
