Abstract
In the process of producing a lithium ion battery, one or more compounds of Formula 1, 2, 3 or 4 (e.g., N,N-dimethylpropionamide), is used as the solvent in the step of forming a slurry from an active material (e.g., lithium cobalt oxide), a conductive agent (e.g., carbon black), and a binder polymer (e.g., polyvinylidene fluoride).
