Patent number: 7825629Abstract: A system and method for charging a rechargeable, or secondary, battery including a series string of cells, includes a topology of charging sources that selectively provides charging current to cells that need to be charged, but avoids overcharging cells that are already charged above a predetermined voltage threshold. Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and by-passes battery cells that are fully charged or become fully charged.Type: GrantFiled: July 2, 2009Date of Patent: November 2, 2010Assignee: EaglePicher TechnologiesInventors: William B.

Patent number: 7826197Abstract: A modular energy storage device comprises a customer-defined parameter, such as electrical capacity, a can that has a dimension based on the customer-defined parameter, an electrode package that has properties based on the customer-defined parameter, and a header that has a configuration that is not dependent on the customer-defined parameter. A method for producing the modular energy storage device comprises generating a standardized energy storage device configuration, receiving a customer-defined parameter, and modifying the standardized energy storage device configuration according to the customer-defined parameter. The step of modifying the standardized energy storage device configuration comprises the steps of modifying the electrode package without modifying the location of the current collectors, modifying the length of the can according to the customer-defined parameter, and using the header already developed to complete construction of the modular energy storage device.Type: GrantFiled: November 3, 2007Date of Patent: November 2, 2010Assignee: EaglePicher TechnologiesInventors: Scott Gramm, Clay Braziller, Grant Farrell

Publication number: 20090226809Abstract: An improved cathode suitable for lithium-sulfur batteries, a battery including the cathode, and a battery including a separator containing inorganic fillers are disclosed. The cathode includes sulfur and a metal oxide and optionally includes an additional polymeric material. The metal oxide reduces dissolution of sulfur at the cathode and reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance. The separator also reduces unwanted diffusion of sulfur species.Type: ApplicationFiled: March 2, 2009Publication date: September 10, 2009Applicant: EAGLEPICHER TECHNOLOGIES, LLCInventors: Viet Vu, Ramanathan Thillaiyan, Mai Sayarath, Ernest Mdzebet, Umamaheswari Viswanathan

Patent number: 7504177Abstract: A reserve battery including a dual-purpose fill port member that also operates as a battery activation mechanism. The reserve battery includes a frangible barrier positioned inside a case. The frangible barrier divides the case into a first compartment holding cell electrodes and a second compartment capable of holding an electrolyte in isolation from the first compartment. Positioned in the second compartment proximate to the frangible barrier is a fill port member that is movable in response to an applied force for rupturing the frangible barrier. The fill port member also has a fluid passageway for use in transferring an amount of the electrolyte to the second compartment. The dual purpose of the fill port member is that it efficiently uses the available space and permits the design and production of a more compact reserve battery for use in space-limited applications, such as artillery shells.Type: GrantFiled: August 23, 2004Date of Patent: March 17, 2009Assignee: Eaglepicher Technologies, LLCInventor: Mark John Peabody
