Patent number: 8733465Abstract: A device for suppressing fires generated by lithium-ion batteries exhibiting thermal runaway. The device can include a thermally insulating enclosure for housing one or more battery cells. A fluid delivery system having a heat/temperature sensitive tube passes through each enclosure and contains an agent capable of extinguishing fires. When the cell or battery starts to undergo thermal runaway, the increase in temperature or the eruption of open flame causes the fluid delivery system to rupture inside the enclosure. The agent leaks out of the rupture and is transported into the enclosure and onto the malfunctioning cell or battery. Any fire is suppressed and the cell or battery is cooled down by the agent.Type: GrantFiled: May 22, 2013Date of Patent: May 27, 2014Assignee: LITHFIRE-X, LLCInventors: Gerald Grattan Flood, Ronald Michael Butler

Patent number: 8734996Abstract: An anode of a lithium battery includes a supporting member and a carbon nanotube film disposed on a surface of the support member. The carbon nanotube film includes at least two overlapped and intercrossed layers of carbon nanotubes. Each layer includes a plurality of successive carbon nanotube bundles aligned in the same direction. A method for fabricating the anode of the lithium battery includes the steps of: (a) providing an array of carbon nanotubes; (b) pulling out, by using a tool, at least two carbon nanotube films from the array of carbon nanotubes; and (c) providing a supporting member and disposing the carbon nanotube films to the supporting member along different directions and overlapping with each other to achieving the anode of lithium battery.Type: GrantFiled: December 14, 2007Date of Patent: May 27, 2014Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Chen Feng, Kai-Li Jiang, Liang Liu, Xiao-Bo Zhang, Shou-Shan Fan

Publication number: 20140134463Abstract: A lithium thionyl chloride cell having, in a can, a cathode collector, a solution of lithium tetra-chloroaluminate (LiAlCl4) in thionyl chloride (SOCl2), and a lithium alloy anode. The lithium alloy anode has lithium and an alloy material selected from the group consisting of magnesium and aluminum. The composition of lithium in relation to the alloy material ranges from 95:5 to 50:50, by weight, such that the total capacity of the lithium plus the alloying material is greater than the capacity of the thionyl chloride and at the same time the capacity of the lithium alone is less than or equal to the capacity of the thionyl chloride.Type: ApplicationFiled: May 20, 2013Publication date: May 15, 2014Inventors: Arden Phillip Johnson, John S. Miller
