MIT WASSER ANGEMACHTES ELEKTRODENMATERIAL UND SEINE VERWENDUNG IN ELEKTROCHEMISCHEN ZELLEN

摘要

A method for preparing an electrode component comprises mixing an electrode active material in a water-based environment with the aid of surfactants. A preferred embodiment of this process comprises combining a high surface area carbonaceous cathode active material with a water/surfactant mixture, and then adding a fluoro-polymer as the binder material to the slurry. The resulting paste is processed and formed into the cathode material. This process replaces the use of isopropyl alcohol with the water/surfactant mixture as the solvent. Preferred surfactants include those of the polyglycol family.
