NOVELTY - A poros graphene doped nitrogen/carbon nano-tube composite conductive agent preparing method involves obtaining seed liquid and nano hole oxidized graphene suspension. The obtained nanometer hole graphene oxide suspension and carbon nanometer tube suspension liquid are mixed and processed to obtain mixed suspension. Anaerobic denitrifying bacteria culture liquid is added into the mixed suspension. Denitrifying amine seed liquid is inoculated into the mixed suspension. The inoculated liquid is purified and dried to obtain a finished product. USE - Method for preparing poros graphene doped nitrogen/carbon nano-tube composite conductive agent that is utilized in lithium ion battery. ADVANTAGE - The method enables preparing the conductive agent with easy amplification, in a simple, control and cost-effective manner. DETAILED DESCRIPTION - A poros graphene doped nitrogen/carbon nano-tube composite conductive agent preparing method involves inoculating yellow spore raw Phanerochaete chrysosporium into seed cultivation culture liquid and anerobic culture liquid to obtain seed liquid. Graphene oxide suspension and nutrient limited culture liquid are added into the seed liquid and shaked at constant temperature. The mixed seed liquid is oxidized and dispersed in de-ionized water to obtain the nano hole oxidized graphene suspension. The obtained nanometer hole graphene oxide suspension and carbon nanometer tube suspension liquid are mixed and processed under ultrasonic condition to obtain mixed suspension. Anaerobic denitrifying bacteria culture liquid is added into the mixed suspension. Denitrifying amine seed liquid is inoculated into the mixed suspension. The inoculated liquid is purified and dried to obtain a finished product.
