Abstract
A positive electrode slurry composition, a positive electrode manufactured using the same, and a battery including the positive electrode. The positive electrode slurry composition includes a positive electrode active material, a binder, an alcohol, and water, wherein a content of the alcohol is in a range of 0.1 to 10% by weight, based on a total weight of the composition. The slurry composition for manufacturing a positive electrode has effects of highly improving the dispersibility of the positive electrode active material and the conductive material, decreasing the surface roughness of an electrode, and remarkably reducing a curling phenomenon in the electrode. Also, the slurry composition has an economic advantage in that a dispersing agent is not used or an amount of the dispersing agent used can be remarkably reduced.
