Abstract
A negative electrode slurry and a method of preparing the same. The negative electrode slurry includes lithium titanium oxide (LTO), a carboxylic acid-containing polymer dispersant, a binder, and an aqueous solvent. The carboxylic acid-containing polymer dispersant has a weight average molecular weight (Mw) of 2,500 g/mol to 500,000 g/mol and is present in an amount of 1.5 parts by weight to 20 parts by weight with respect to 100 parts by weight of the lithium titanium oxide.
