Silicon-oxygen composite negative electrode material and manufacturing method thereof

The invention discloses a silicon-oxygen composite negative electrode material which is used for manufacturing a negative electrode of a lithium battery; the negative electrode material comprises an inner core, a coating layer and a middle layer, wherein the coating layer wraps the inner core, and the middle layer is positioned between the inner core and the coating layer, wherein the middle layercomprises non-lithium silicate, and the non-lithium silicate refers to non-lithium silicate, wherein the mass content of the non-lithium silicate in the middle layer is gradually decreased from the middle layer to the inner core. The decrementing comprises a gradient reduction from the middle layer to the inner core, and the gradient reduction refers to the fact that the mass-duty ratios on the circumference parts which have the same central distance from the inner core are the same, and when the distance from the center of the inner core is reduced, the mass-duty ratio is reduced step by step. The non-lithium silicate is generated in situ on the outer layer of the inner core, and has a non-water-soluble or non-alkaline or weakly alkaline compact structure, so that the dissolution of theinternal water-soluble lithium silicate can be effectively relieved; and the pH value of the ghost-eye composite negative electrode material can be lowered.
