Industry News US Battery Aids Michigan State Police in an Operation to Apprehend Battery Thieves US Battery Manufacturing aided the Michigan State Police in apprehending thieves who were stealing deep-cycle batteries from RV dealerships. After more than 80 batteries were stolen from multiple thefts in a single location, the Michigan State Police Technical Service Unit contacted US Battery Manufacturing to assist them with a plan that would help apprehend the suspects responsible. Specialist Trooper Paul Gonyeau, of the Michigan State Police Fifth District Technical Services Unit, asked US Battery to supply the Michigan State Police with several empty battery cases. "It was subsequently determined that the use of batteries equipped with live GPS units would be the most effective method," said Specialist Trooper Paul Gonyeau. The plan would allow the team to monitor, identify and apprehend the suspects involved, without alerting them to the presence of law enforcement. "We were able to make the appropriate modifications and enclose live GPS units in the US Battey cases," said Gonyeau. "These units were then put into place at the R.V. dealer and monitored." According to Gonyeau, it only took a few weeks until the suspects struck again, stealing more than a dozen batteries. Two of the batteries stolen were the US Battery cases equipped with the GPS units. "Within moments of the theft, the suspects were being monitored by law enforcement and stopped within a few miles of the RV dealer with all of the stolen batteries still in their possession. During interviewing, the main suspect admitted to all of the previous thefts," said Gonyeau. "Thanks to the assistance of US Battery, this operation was very successful!" "We were more than willing to assist Michigan State Police in this operation," says Dwayne Porter, Marketing Manager US Battery Manufacturing. "Lead and other metals have become more valuable recently making battery theft a more lucrative business for thieves. We were proud to be given this opportunity and will always do our part to prevent crime whenever possible." O2Micro's Multi-Cell Battery Monitoring Invention Receives Patent From Japanese Patent Office O2Micro International Limited has announced a patent grant from the Japanese Patent Office for its Multi-cell Battery Pack Monitoring systems and methods. O2Micro was issued eight claims under Japanese Patent number 5,324,483. Similar to the US version issued under patent number 8,253,383, this invention provides a current-mode, voltage detection circuit and methodology to protect a multi-cell, rechargeable battery pack from over-voltage or under-voltage fault conditions. "This invention protects battery packs and extends battery life for handheld devices, desktop and notebook computers, electric vehicles (EVs) and hybrid EVs (HEVs)," said Bill Densham, strategic marketing director, O2Micro. 26 Battery Power * November/December 2013 Battery Electrode Materials Based on Layered Sodium Titanates Berkeley Lab researcher Marca Doeff and colleagues have developed a new electrode material based on a layered sodium titanate compound that can be used to form electrodes for large electric grid storage and other rechargeable battery systems. The researchers found that anodes can be fashioned from a parent compound consisting of Ti6O14 units connected into a corrugated layered structure with hydrated Na cations and protons in the interlayer spaces. Performance is improved after water is irreversibly removed during high heat treatment, forming a compact, layered sodium titanate that can reversibly intercalate either sodium or lithium. This electrochemical process makes the material a suitable electrode material for either sodium or lithium batteries. Lithium- or sodium-based storage systems have the theoretical energy capacity needed for efficient grid storage systems, but the electrode materials available to date are too costly and have a short cycle life. The Berkeley Lab layered sodium titanate electrodes are comprised of lower cost, Earth-abundant materials and can potentially result in a higher energy density and rate capability for devices than those that use carbonaceous materials as anodes. The new electrode materials using titanium-based oxides also have the potential to be more durable than alloy anodes based on silicon or tin that undergo substantial volume changes during the charge/discharge cycle. Large sodium batteries theoretically have the energy densities and economies required for electric grids responding to fluctuations inherent to wind or sun power. Because the Berkeley Lab sodium titanate electrodes also intercalate lithium, they could also be developed as lower cost electrodes for the high capacity lithium-ion batteries used in electric vehicles. Aquion Energy and Siemens Industry Integrate Technologies for Developing Microgrid and Grid Energy Storage Systems Aquion Energy, Inc., a developer and manufacturer of Aqueous Hybrid Ion (AHI) batteries and energy storage systems, has signed a memorandum of understanding (MOU) with Siemens Industry, Inc., under which both parties will test the integration of Aquion's AHI batteries and Siemens' Sinamics S120 drive technology. As part of the MOU, Siemens purchased an initial set of Aquion batteries for immediate shipment to their manufacturing and test facility in Alpharetta, Ga. "With its novel Aqueous Hybrid Ion technology, Aquion has emerged with an exciting new energy storage solution. We want to explore the Aqueous Hybrid Ion technology proposed by Aquion, validate its capabilities and potential for offering cost effective grid-scale deployments and energy efficient Microgrid and Renewables support functions" Siemens' Sinamics S120 inverter solution and Aquion's AE12 Battery Module product are currently under high voltage test at Aquion's R&D facility in Pittsburgh, and will undergo additional joint testing at Siemens' Alpharetta facility. Based on Aquion's breakthrough AHI battery technology, the AE12
