Abstract
This invention provides a lithium secondary battery comprising a positive electrode, and a negative electrode comprising a carbonaceous material which is capable of absorbing or desorbing lithium ion, wherein the carbonaceous material comprises 1 to 10% by weight of boron and 0.1 to 1% by weight of oxygen, and has an intensity ratio (P.sub.101 /P.sub.100) i.e., a ratio in intensity of a (101) diffraction peak P.sub.101 to a (100) diffraction peak P.sub.100 as measured by means of powder X-ray diffraction, of 2 or more.
