Embodiment
[0038] The carbon material used as the matrix is mesoporous carbon prepared by SBA15 template method and KB600 carbon powder in a mass ratio of 2:1 to 1:2, and the binder is polyvinylidene fluoride with a molecular weight of 900,000 to 1 million. between.
[0039] Example scheme
[0040] The mass ratio percentage of each material ratio of the positive electrode of the embodiment of table 1
[0041]
[0042] The above table is the mass proportion of various substances in the specific examples.
[0043] Specific method: (1) Weigh the matrix carbon material and sulfur powder according to the specific gravity in the table, ball mill for more than 4 hours, weigh PVDF powder according to the specific gravity and add it to the carbon-sulfur mixture, ball mill again for more than 2 hours, and add the dispersant N-methyl Pyrrolidone NMP, so that the solid content in the slurry is 30%, and after mixing evenly, ball milling for more than 4 hours to obtain the slurry; (2) The slurr...
