The present invention relates to a slurry for a positive electrode of a secondary lithium battery, a preparation method for the same, and an application thereof. The slurry for a positive electrode of a lithium secondary battery comprises an active material of the positive electrode, a conductive agent, a binding agent, and an organic solvent. The organic solvent has a structure as shown by formula (I), with R.sub.3 being a C1-C6 alkyl group, R.sub.1 and R.sub.2 being either hydrogen, a C1-C6 alkyl group, or a C1-C6 ether-linked hydrocarbyl group, and R.sub.1 and R.sub.2 being capable of binding with the connected nitrogen atom to form a cyclic structure. The slurry of a positive electrode of a secondary lithium battery has superior performance, is environmentally friendly, mild and safe, and causes no irritation, thereby reducing damage to operators, and reducing the burden on the environment.
