Abstract

Provided herein is a method of preparing anode slurries of lithium-ion batteries. The silicon-based material is uniformly dispersed prior to mixing with other components of the anode slurry. The method disclosed herein is capable of avoiding agglomeration of nano-sized silicon-based material and effectively dispersing the nano-sized silicon-based material uniformly in anode slurries. Anodes coated with the anode slurries disclosed herein also show an improvement in the electrical conductivity.
