Monodisperse carbon microspheres derived from potato starch for asymmetric supercapacitors

A method for producing an activated carbon material includes forming an aqueous mixture of a natural, non-lignocellulosic carbon precursor and an inorganic compound, heating the mixture in an inert or reducing atmosphere, cooling the heated mixture to form a first carbon material, and removing the inorganic compound to produce an activated carbon material. The activated carbon material is suitable to form improved carbon-based electrodes for use in high energy density devices.

Preparation of carbon spheres from potato starch and its stabilization mechanism

The invention discloses a method for preparing starch-based activated carbon microsphere with high specific surface area, which pertains to the technology of preparing activated carbon microsphere. The process of the method comprises: cereal starch, potato starch, pea starch and banana and plantain fruit starch are taken as raw material, which is oxidized under constant temperature in an oxidizing atmosphere; oxidized starch, under the protection of nitrogen, is carbonized in a carbonization furnace, and starched-based carbon microsphere with the original shape of starch granules is produced; the prepared carbon microsphere and activating agent are mixed and dipped and dried, and the mixture obtained, under the protection of nitrogen, is activated in an activating furnace; the activated product is washed and centrifugally separated and dried, and the starch-based activated carbon microsphere with high specific surface area is obtained. The method of the invention has simple process, low price for raw material and wide raw material source, and can realize large-scale production easily.
