摘要：
The invention aims to improve the charge/discharge cycle characteristics of an anodic carbon material for a lithium secondary battery. An anodic carbon material for a lithium secondary battery according to the present invention comprises: particles containing carbon, or a metal or metalloid, or an alloy, oxide, nitride, or carbide thereof, the particle capable of absorbing and releasing lithium ions; a resinous carbon material enclosing the particles; and a network structure formed from carbon nanofibers and/or carbon nanotubes that bond to the surfaces of the particles and that enclose the particles.
