Abstract
The present disclosure relates to a secondary graphite particle comprising an initial natural graphite particle of excellent high capacity and output characteristic, aggregated, bonded or assembled with an initial artificial graphite particle of excellent cycle characteristic and swelling characteristic, thus having superior rollability that leads into increased density, a negative electrode using the secondary graphite particle as a negative electrode active material, and a secondary lithium battery comprising the negative electrode. Accordingly, the secondary lithium battery comprising the secondary graphite particle as described above as the negative electrode active material has an effect of enhanced high rate charging and discharging capability, cycle characteristic and swelling characteristic.
