摘要:
Provided is a slurry composition for a secondary battery negative electrode that has excellent producibility and can suppress cell swelling and an increase in internal resistance in a secondary battery. The slurry composition for a secondary battery negative electrode contains a negative electrode active material, a particulate polymer, and water. The negative electrode active material includes a carbon-based negative electrode active material having a surface functional group content of at least 0.9% and not more than 1.5%, and a BET specific surface area of 2.5 m2/g or less. The particulate polymer has a surface acid content of at least 0.2 mmol/g and not more than 2.0 mmol/g.
