A porous carbon output which has layer joint structure, a manufacturing method for the same, and directions for use for the same

Japanese Patent JP5916841

B2

Inexpensive product consisting of porous carbon, with a pore structure which is suitable for retaining electrode parts which can be used in particular for a use as an electrode material for a lithium-sulphur secondary battery, and a method comprising the following method steps: (a) providing a template consisting of inorganic material which contains spherical nanoparticles and pores, (b) infiltrating the pores of the template with a precursor for carbon of a first variety, (c) carbonizing so as to form an inner layer on the nanoparticles with a first microporosity, (d) infiltrating the remaining pores of the template with a precursor substance for carbon of a second variety, (e) carbonizing the precursor substance, wherein an outer layer with a second microporosity which is lower than the first microporosity is produced on the inner layer, and (f) removing the template so as to form the carbon product with layer composite structure, comprising an inner layer consisting carbon with a first, relatively high microporosity, which has a free surface facing a cavity, and an outer layer consisting of carbon with a second, relatively low microporosity, which has a free surface facing away from the cavity.
