Patent number: 10014518Abstract: In one embodiment, a positive electrode is formed by a process that includes forming a slurry including particles dispersed within a liquid from a electrode formulation and the liquid such that the particles have a particle size distribution D50 of 15 microns or less, coating the slurry on a collector; and drying the coated 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 liquid consists essentially of water or a mixture of water and an alcohol. When the liquid consists essentially of the mixture, the alcohol is present in an amount of less than 10% by weight, based on the weight of the slurry. When the liquid consists essentially of water, the slurry is formed from the electrode formulation, the liquid, and an arene-capped polyoxoethylene surfactant.Type: GrantFiled: October 18, 2013Date of Patent: July 3, 2018Assignee: Johnson Controls Technology CompanyInventors: Junwei Jiang, Yongkyu Son, Bernhard M. Metz, Patrick T. Hurley, Qiang Luo, Kavi G. Loganathan

Patent number: 9117596Abstract: Electrodes, which may be composite capacitor electrodes, include carbon fibers, illustratively chopped carbon fibers having an aspect ratio of from about 100-5000, have been treated with a non-ionic surfactant, specifically the polyoxyethyleneglycol octophenyl ether, Triton X-100, to increase the hydrophilicity of the fibers. The capacitive electrodes prepared with the surface-modified carbon fibers exhibit increased charge acceptance.Type: GrantFiled: March 27, 2013Date of Patent: August 25, 2015Assignee: Johnson Controls Technology CompanyInventors: Kavi G.
