Effect of coke orientation on the electrochemical properties of lithium-ion battery anode
In this study, Needle and Regular coke, which has different crystalline and orientation characteristics, were graphitized, and the effect of crystal changes on electrochemical performance was investigated. The initial efficiency and capacity were mainly influenced by the shapes and specific surface...

| description | In this study, Needle and Regular coke, which has different crystalline and orientation characteristics, were graphitized, and the effect of crystal changes on electrochemical performance was investigated. The initial efficiency and capacity were mainly influenced by the shapes and specific surface areas of the particles, and the graphitized sample showed excellent initial efficiency due to having a lower specific surface area (decrease in exposed edge surfaces) than the coke. However, rate performance shows excellent in the graphitized sample of regular coke due to its defects and short lithium-ion transport path.
