Abstract
A method of making a positive electrode includes forming a slurry of particles using an electrode formulation, a diluent, and oxalic acid, coating the slurry on a collector and drying the coating on the collector to form the positive electrode. The electrode formulation includes an electrode active material, a conductive carbon source, an organic polymeric binder, and a water soluble polymer. The diluent consists essentially of water.
