Anode material of lithium battery and its production method, lithium secondary battery employing the same

The invention relates to a lithium battery anode material, a manufacturing method thereof, an application thereof and a lithium secondary battery made of the material. The lithium battery anode material comprises a porous lithium oxide micron particle which comprises a plurality of porous lithium oxide nano particle; the inside of each porous lithium oxide nano particle is provided with a first conductive layer, a hole, a second conductive layer and conductive fiber; the hole is defined by the connection of the porous lithium oxide nano particles; the second conductive layer is coated on the surface of at least one of the porous lithium oxide nano particles and contacts with the first conductive layer to form a 3-D conductive network among the porous lithium oxide micron particles; and the conductive fiber is connected with the second conductive layer. The inside of each porous lithium oxide micron particle is provided with a plurality of nano lithium oxide particles, a nano porous channel and a nano 3-D conductive network. In addition, the conductive fiber is connected to the second conductive layer.
