Anode slurry for secondary battery

Abstract

Provided herein is an anode slurry for lithium-ion batteries, comprising a silicon-based material, a porous carbon aerogel, a binder material, a carbon active material, and a solvent, wherein the porous carbon aerogel has an average pore size from about 80 nm to about 500 nm. The porous carbon aerogel in the anode slurry disclosed herein provides sufficient space for expansion of the silicon-based material during intercalation of lithium ions. Cracking of the silicon-containing anode layer is prevented.
