Patent number: 10270072Abstract: A method of assembling a rechargeable battery is disclosed. The method includes inserting rechargeable energy storage cells into a battery housing, the battery housing having a base portion, a side portion extending from the base portion, and an aperture defined by the side portion, wherein the rechargeable energy storage cells are inserted into the battery housing through the aperture; installing an insulator on the rechargeable energy storage cells; and securing a housing cover to the battery housing such that the insulator and the rechargeable energy storage cells are maintained in compression between the housing cover and the housing base portion. Also disclosed is a rechargeable battery including a battery housing, a housing cover, a plurality of rechargeable energy storage cells disposed within the battery housing, and an insulator disposed between the rechargeable energy storage cells and the housing cover and maintained in compression.Type: GrantFiled: May 9, 2016Date of Patent: April 23, 2019Assignee: General Electric CompanyInventors: Roger Bull, James Sudworth, Paul Sudworth, Stuart Towle

Patent number: 9257698Abstract: A positive electrode composition is provided. The positive electrode composition includes at least one electroactive metal selected from the group consisting of titanium, vanadium, niobium, molybdenum, nickel, iron, cobalt, chromium, manganese, silver, antimony, cadmium, tin, lead, copper, zinc, and combination thereof, an alkali metal halide, and aluminum, present in an amount of at least 0.5 weight percent, based on the weight of the positive electrode composition. Optionally, an amount of sodium iodide of up to about 1.0 weight percent, based on the weight of the sodium halide in the positive electrode composition, is included. The composition may be included in a positive electrode with a molten electrolyte salt comprising the reaction product of an alkali metal halide and an aluminum halide. An energy storage device including the composition is provided, as well as a method of operating the device.Type: GrantFiled: November 13, 2012Date of Patent: February 9, 2016Assignee: General Electric CompanyInventors: Robert Christie Galloway, Job Thomas Rijssenbeek, Guillermo Daniel Zappi, James Sudworth

Patent number: 9147910Abstract: A system and method of use including a controller responsive to a deviation in absolute value or relative slope and operable to terminate a discharge operation in an energy storage device is provided. The absolute value or relative slope is determined at sampling frequency based upon a combination of measured operating parameters, for example, potential and current. Any deviation in the absolute value or relative slope indicates that a threshold limit in the available energy of the system has been reached, for example when active materials in the device are at a point of depletion, indicating a need to cease the discharge operation. The system and method operate on a real-time basis, providing instantaneous SOH information with regard to the device.Type: GrantFiled: December 28, 2011Date of Patent: September 29, 2015Assignee: General Electric CompanyInventors: Christopher James Chuah, Roger Bull, James Sudworth, Vincent Boccanfuso, David James
