Abstract

The present disclosure provides an apparatus and method for preparation of negative electrode material using length-wise graphitization of carbon. The apparatus includes one or more graphite boxes, configured to store powdered coke. The one or more graphite boxes are enabled to be accommodated inside a refractory, encapsulated by a cooling jacket configured to regulate surface temperature of the apparatus. The one or more graphite boxes have one or more openings for refilling of powdered coke and collection of prepared material, the one or more openings being covered by one or more first lids and one or more heat insulating second lids. The apparatus includes one or more graphite electrodes coupled to the one or more graphite boxes and the refractory. One or more heating elements detachably coupled to the one or more graphite electrodes are enabled to receive electric power and uniformly heat the powdered coke.
