Abstract

See full text

There is provided a method for manufacturing a bacterium-produced cellulose carbon having a sufficient specific surface area, and a high mechanical strength. The method manufactures a bacterium-produced cellulose carbon by carbonizing cellulose produced by thermally treating, and the method includes a cellulose forming step S1 of forming bacterium- produced cellulose whereby cellulose nanofibers are dispersed using a bacterium; an impregnating step S2 for impregnating the bacterium-produced cellulose with a supercritical fluid; a drying step S3 of vaporizing the supercritical fluid from the bacterium-produced cellulose containing the supercritical fluid and obtaining a dry product; and a carbonizing step S4 of heating and carbonizing the dry product in an atmosphere not causing combustion of the dry product.
