Abstract

A method for preparing a spheronized carbonaceous negative electrode active material, including the steps of: mixing microgranular scaly graphite with macrogranular scaly graphite, wherein the macrogranular scaly graphite has a larger average particle diameter than the microgranular scaly graphite, to form a mixture, and spheronizing the mixture to prepare spheronized granulated particles; carrying out carbon coating of the spheronized granulated particles; and disintegrating the carbon-coated spheronized granulated particles.
