A method for making a soft carbon includes providing a coke, and subjecting the coke to a carbonization process. The carbonization process includes a preliminary calcination treatment conducted by calcining the coke at a first temperature ranging from 800&#xb0; C. to 1000&#xb0; C. to obtain a pre-calcinated coke, followed by a main calcination treatment conducted by calcining the pre-calcinated coke at a second temperature ranging from 1000&#xb0; C. to 1200&#xb0; C., and/or a surface-modifying calcination treatment conducted by calcining the pre-calcinated coke in the presence of a carbonaceous material for modifying surfaces thereof at a third temperature ranging from 1000&#xb0; C. to 1200&#xb0; C. A soft carbon made by the method is also disclosed.
