Controlling the Structure and Electrochemical Properties of Anode Prepared from Phenolic Resin for Li-ion Batteries

Abstract

The type and molecular weight of precursor has significant influence on the structural characteristics and electrochemical performances of hard carbon which derived from phenolic resins. A series of hard carbon samples have been prepared by carbonization treatment of Novolak and Resole with different molecular weight under vacuum. Take advantage of the large layer spacing, more defects and unique pores distribution of the hard carbon that prepared from Resole with low molecular weight, which exhibits an excellent reversible capacity of 606 mA h g-1 and a superior rate performance.
