POROUS CARBON PRODUCT, METHOD FOR THE PRODUCTION THEREOF, AND USE OF THE SAME |
摘要 |
For use as electrode material for a lithium battery, porous templates are impregnated with a carbon feedstock that can be graphitized. This frequently results in only a low thickness of the deposited, graphite-like layer, such that generally several such infiltration and carbonation processes must be carried out consecutively. In order to provide a cost-effective product which is made of porous carbon and has high porosity and a low surface, according to the invention a method comprises the following method steps: (a) preparing a porous carbon structure having a large specific surface, (b) infiltrating the carbon structure with a precursor substance for carbon that can be graphitized, (c) carbonizing the precursor substance to form the carbon product having a low specific surface, wherein preparing the carbon structure according to method step (a) comprises the following: (I) preparing a template containing pores, (II) infiltrating the pores of the template with a solution that contains a precursor of carbon that cannot be graphitized, (III) carbonizing the precursor forming the carbon structure having the first specific surface, and (IV) removing the template. |
