ABSTRACT:
The present invention provides a lithium secondary battery which has an anode, a separator, a cathode and an electrolyte and which employs intercalation and deintercalation reaction of lithium ions. The anode and/or the cathode of the secondary battery contains a carbonaceous material having a structure in which pores are oriented. The lithium secondary battery exhibits a high charge-discharge efficiency, a high energy density and a long cycle life. The present invention also provides a method of forming the lithium secondary battery including the carbonaceous material having oriented pores, by using an orienting material.
