NOVELTY - A composite electrode material (M1) comprises a carbon coated complex oxide, fibrous carbon and a binder.    USE - As a composite electrode material used to form electrodes (Claimed) useful in lithium batteries and electrochemical cells for high-power applications such as power tools and hybrid electric vehicles.    ADVANTAGE - The composite material has a high mechanical strength that is beneficial during intercalation and de-intercalation of lithium where volume change of the particles and the electrode occurs. The composite material is capable of adsorbing the volume change during charge/discharge of the cell. In composite electrode materials consisting of nanoparticles of a complex oxide particles, it is difficult to create a channel structure and a porosity which is suitable for an electrode, when the electrode is made by calendaring. The presence of the fibrous carbon in the composite material comprising nanoparticles creates a multi-channel structure, which improves the wetability of the material by a liquid electrolyte. Thus, the surface and the core of the particles are accessible to the electrolyte, which enhances the ionic conductivity locally on the particle. As fibrous carbon has a high conductivity, there is no need to add another source of carbon in the composite electrode material. The fibrous carbon increases conductivity locally at each particle and creates a conductive network in the electrode material. The higher conductivity yields high capacity (mAh/g) at high charge/discharge rates. In addition, high capacity is still achieved at low temperature, in particular at less than -20 degrees C. The presence of fibrous carbon in a composite electrode material contributes to form a stable passivation layer on the surface of the electrode in an electrochemical cell having a solid electrolyte, so that the irreversible capacity loss (ICL) decreases. The resistance of a composite electrode containing fibrous carbon is reduced, so that the voltage drop (IR) is very small, which provides lower volumetric specific impedance (VSI) and lower area specific impedance (ASI). These specifications are necessary for high-power applications such as power tools and hybrid electric vehicles.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following    (1) preparing the composite electrode material (M1) involving co-grinding an active electrode material and fibrous carbon, and adding a binder to the co-grinded mixture to lower the viscosity of the mixture; and    (2) a composite electrode, comprising a composite electrode material (M1) on a current collector.
