Silicon-based composite material with three-dimensional bonding network for lithium-ion batteries

摘要

The present invention relates to a silicon-based composite material having a three-dimensional bonding network and improved interaction between binder and silicon-based material containing silicon-based material, treatment material, a carboxyl-containing binder, and conductive carbon, wherein the treatment material is selected from the group consisting of polydopamine or silane coupling agent with amine and / or imine groups, and an electrode material and a lithium-ion battery containing the silicon-based composite material, and a method for producing the silicon-based composite material.
