If the electrode slurry is poorly mixed, the conductive additive will not disperse well enough. Assembling a battery without properly dispersing the active material and the additives will concentrate the charge, which is undesirable because it causes non-uniform battery reactions; batteries need homogenous slurries for efficient charge transfer.
