Patent number: 11211642Abstract: A process for treating an electrochemical cell is presented. The process includes charging the electrochemical cell in a discharged state to at least 20 percent state-of-charge of an accessible capacity of the electrochemical cell at a first temperature to attain the electrochemical cell in a partial state-of-charge or a full state-of-charge and holding the electrochemical cell in the corresponding partial state-of-charge or full state-of-charge at a second temperature. The first temperature and the second temperature are higher than an operating temperature of the electrochemical cell.Type: GrantFiled: December 12, 2017Date of Patent: December 28, 2021Assignee: General Electric CompanyInventors: Karthick Vilapakkam Gourishankar, Satya Kishore Manepalli, Job Thomas Rijssenbeek, Hari Nadathur Seshadri, Anbarasan Viswanathan

Patent number: 11098724Abstract: A control system and method utilizing one or more processors that are configured to determine contaminant loading of blades of a turbomachinery compressor based on one or more environmental conditions to which the turbomachinery compressor is exposed and one or more atmospheric air inlet conditions of the turbomachinery compressor. The one or more processors then determine a corrosion contaminant concentration on the blades of the turbomachinery compressor based on the contaminant loading that is determined and determine an upper limit on or a distribution of potential corrosion of the blades of the turbomachinery based on the corrosion contaminant concentration, at least one of the environmental conditions to which the turbomachinery compressor is exposed, and the corrosion contaminant concentration that is determined.Type: GrantFiled: May 23, 2017Date of Patent: August 24, 2021Assignee: GENERAL ELECTRIC COMPANYInventors: Guruprasad Sundararajan, Prashanth Pillai, Muralikrishan R., Rebecca Hefner, Bradford Foulkes, Anbarasan Viswanathan, Robert G. Kelly

Publication number: 20130108931Abstract: An embodiment of this invention is directed to a positive electrode composition that includes a first group of granules that contain about 30% by volume of at least one metal or electrically-conductive carbon, or combinations thereof; and a second group of granules that contain at least about 60% by volume of a metallic salt, and less than about 30% by volume of a metal. A porous structure based on a material that is resistant to non-passivating oxidation and alkaline electrolysis may be used in place of the second group of granules. An article that includes a positive electrode based on such a composition is also described, as well as related energy storage devices.Type: ApplicationFiled: October 31, 2011Publication date: May 2, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Richard Louis Hart, Michael Alan Vallance, Karthick Vilapakkam Gourishankar, Hari Nadathur Seshadri, Anbarasan Viswanathan

Publication number: 20110108439Abstract: An oxide-ion sensor includes an oxygen electrode, a sense electrode and a saturated (reference) electrode. The sense electrode is operated at a substantially constant current for determining an instantaneous value of a dissolved oxide-ion concentration in the molten salt electrolyte. The saturated electrode is used to determine a reference value of the dissolved oxide-ion concentration in the molten salt electrolyte. A dissolved oxide-ion concentration in the molten salt electrolyte is continuously monitored in-situ during the molten-salt based electrochemical reduction process by determining an equilibrium potential between the sense electrode and the saturated electrode with the sense electrode carrying a small current in a circuit that is completed using the oxygen electrode.Type: ApplicationFiled: November 9, 2009Publication date: May 12, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: Karthick Vilapakkam Gourishankar, Andrew Maxwell Peter, Hari Nadathur Seshadri, Anbarasan Viswanathan
