Abstract
The present invention provides a composite material for positive electrodes of lithium batteries, which provides a lithium battery having excellent high rate electrical discharge characteristics, has a sufficiently secured diffusion passage for Li, and has high conductivity, a process for producing the same, as well as a positive electrode and a battery using the composite material for positive electrodes of lithium batteries. The present invention relates to a composite material for positive electrodes of lithium batteries, comprising composite particles containing positive electrode active material particles and fibrous carbons, wherein the composite particles have a form in which the positive electrode active material particles are supported by the fibrous carbons.
