  • Publication number: 20110114254
    Abstract: Methods for making composite anodes, such as macroporous composite anodes, are disclosed. Embodiments of the methods may include forming a tape from a slurry including a substrate metal precursor, an anode active material, a pore-forming agent, a binder, and a solvent. A laminated structure may be prepared from the tape and sintered to produce a porous structure, such as a macroporous structure. The macroporous structure may be heated to reduce a substrate metal precursor and/or anode active material. Macroporous composite anodes formed by some embodiments of the disclosed methods comprise a porous metal and an anode active material, wherein the anode active material is both externally and internally incorporated throughout and on the surface of the macroporous structure.

  • Publication number: 20110059364
    Abstract: Disclosed herein are embodiments of lithium/air batteries and methods of making and using the same. Certain embodiments are pouch-cell batteries encased within an oxygen-permeable membrane packaging material that is less than 2% of the total battery weight. Some embodiments include a hybrid air electrode comprising carbon and an ion insertion material, wherein the mass ratio of ion insertion material to carbon is 0.2 to 0.8. The air electrode may include hydrophobic, porous fibers. In particular embodiments, the air electrode is soaked with an electrolyte comprising one or more solvents including dimethyl ether, and the dimethyl ether subsequently is evacuated from the soaked electrode. In other embodiments, the electrolyte comprises 10-20% crown ether by weight.

  • Publication number: 20100273066
    Abstract: A rechargeable lithium-air battery (10) comprises a non-aqueous, organic-solvent-based electrolyte (16) including a lithium salt and an additive containing an alkylene group, disposed between a spaced-apart pair of a lithium anode (12) and an air cathode (14). The alkylene additive may be alkylene carbonate, alkylene siloxane, or a combination of alkylene carbonate and alkylene siloxane. The alkylene carbonate may be vinylene carbonate, butylene carbonate, or a combination of vinylene carbonate and butylene carbonate. The alkylene siloxane may be a polymerizable silane. The polymerizable silane is triacetoxyvinylsilane.

  • Patent number: 7615946
    Abstract: A fan speed control device includes a management selection module, a first and a second buffers, a resistor, a transistor, and a switch. Depending upon whether a motherboard supports a system of a baseboard management control or not, the fan speed control device selectively uses an indicative signal of a serial input and output interface or an indicative signal of the baseboard management control to indicate a power-on status. At the power-on moment, the fan speed control device controls the fan to operate at its minimum speed, so that a system crash due to a power output shortage of a power supply can be avoided. As the system enters stable operation, the fan speed is controlled by a pulse width modulation signal.

  • Patent number: 7540886
    Abstract: A thin-film battery (10) is disclosed which includes a cathode current collector (11), a cathode (12), an electrolyte (13), an anode (14), and an anode current collector (15). The cathode is produced by grinding lithium cobalt oxide or other suitable cathode material to a powder having a mean particle size of between 5 and 12 microns, forming a liquid slurry with the cathode material, casting the liquid slurry upon a substrate, drying the liquid slurry to form a layer of cathode material, and compressing the cathode layer to a generally uniform and smooth thickness of between 5 and 12 microns. The compressed layer is then heated to a temperature which sinters or melts the peripheral edges of the cathode particles together.
