method for manufacturing inorganic particle coated carbon felts and inorganic particle coated carbon felts thereby

摘要

The present invention relates to a carbon felt coated with an inorganic particle which can be used as an anode such as sulfur in a sodium-sulfur (Na-S) battery and a method for producing the carbon felt. The inorganic filler precursor or the inorganic particle powder is mixed with an organic binder It is possible to directly form a coating film composed of only inorganic particles of several tens of nano to several hundreds of nano size on the carbon felt by using it together and to form a uniform coating on the carbon felt without any defects and damage without a separate process. Further, according to the drying direction, a carbon felt having an inclined structure in which the coating film at the lower part is thickened can be obtained.
