example 1
[0021] (1) Put 0.8g of macadamia husks into a vacuum drying oven at 120°C for 6 hours to ensure that there is no moisture at all;
[0022] (2) Put 0.72g of the macadamia husks in (1) into an atmosphere muffle furnace for carbonization, keep it at 800°C for 1h, and the nitrogen gas rate is 50ml / min;
[0023] (3) Put 0.3g of the shell charcoal prepared in (2) into the reactor and pump it to a vacuum, heat the reactor to 200°C, keep it warm for 10 minutes, and then pump it to a vacuum, and then pass in a mixture of 20% fluorine and nitrogen Gas to -0.03Mpa, reaction time is 4h, get fluorinated carbon;
[0024] (4) Grind the carbon fluoride in (3) according to the ratio of carbon fluoride: carbon black: binder (PVDF) = 8: 1: 1, and evenly coat the ground slurry on the carbon-attached aluminum foil , placed in a blast oven for 12 hours to dry. The baked material was placed in a vacuum drying oven and dried in vacuum for 8 hours. Finally, the cutting weight of the positive electr...

[0031] (1) Put 0.5g of apricot shell into a vacuum drying oven at 120°C for 8 hours to ensure that there is no moisture at all;
[0032] (2) Put 0.43g of the coconut shell in (1) into the atmosphere muffle furnace for carbonization, keep it at 800°C for 1h, and the nitrogen rate is 30ml / min;
[0033] (3) Put 0.3g of the shell charcoal prepared in (2) into the reactor and pump it to a vacuum, heat the reactor to 150°C, keep it warm for 60min, and then pump it to a vacuum, and feed a mixture of 5% fluorine and nitrogen Gas to 0Mpa, the reaction time is 8h, to obtain fluorinated carbon;
[0034] (4) Grind the carbon fluoride in (3) according to the ratio of carbon fluoride: carbon black: binder (PVDF) = 8: 1: 1, and evenly coat the ground slurry on the carbon-attached aluminum foil , placed in a blast oven for 12 hours to dry. The baked material was placed in a vacuum drying oven and dried in vacuum for 8 hours. Finally, the cutting weight of the positive electrode material el...
