SILICON/CARBON COMPOSITE MATERIAL WITH HIGHLY COMPACT STRUCTURE, METHOD FOR PREPARING SAME, AND USE THEREOF

The present invention relates to the field of anode materials of lithium batteries, and in particular, relates to a silicon/carbon composite material with a highly compact structure. The silicon/carbon composite material with the highly compact structure includes silicon particles and a carbon coating layer, and further includes a highly compact carbon matrix, wherein the silicon particles are distributed inside the highly compact carbon matrix evenly and dispersively and forms an inner core; and the silicon/carbon composite with the highly compact structure is compact inside without voids or has few closed voids inside. The present invention provides the silicon/carbon composite material with the highly compact structure with a reduced volumetric expansion effect and an improved cycle performance, a method for preparing the same, and a use thereof.
