A method of fabricating nanocomposite anode material embodying a lithium titanate (LTO)-multi-walled carbon nanotube (MWNT) composite intended for use in a lithium-ion battery includes providing multi-walled carbon nanotube (MWNTs), including nanotube surfaces, onto which functional oxygenated carboxylic acid moieties are arranged, generating 3D flower-like, lithium titanate (LTO) microspheres, including thin nanosheets and anchoring the acid-functionalized MWNTs onto surfaces of the 3D LTO microspheres by π-π interaction strategy to realize the nanocomposite anode material.

'Flower-like' LITIO-multiwalled carbon nanotube composite structures with performance as highrate anode-materials for Li-ion battery applications and methods of synthesis thereof

A novel silver-lithium-iodine solid-state energy device and system are disclosed. The rechargeable, self-assembled, dual-function, metal-iodide battery exhibits small size and high deliverable power. Inert until activation, the device may be stored for long periods of time. Upon activation, the device assembles the required electrochemical moieties for operation without external intervention. The device limits short-circuiting and self-discharge of the system by spontaneous reactions at the electrode/electrolyte interfaces, and thus is self-healing. By incorporating both silver and lithium in the same system, a dual function is achieved, whereby the characteristics of a lithium-based battery dominate at a low load and those of a silver-based battery dominate under a high load.

Solid-state silver-lithium / iodine dual-function battery formed via self-assembly

Bimetallic polyanionic materials, such as silver vanadium phosphorus oxide (AgVOPO, SVOP), are promising cathode materials for Li batteries due in part to their large capacity and high current capability. A new synthesis of AgVOPObased on microwave heating is disclosed, where the reaction time is reduced by approximately 100 times relative to other reported methods, and the crystallite size is controlled via synthesis temperature, showing a linear positive correlation of crystallite size with temperature. Reaction times of an hour or less are sufficient to render phase-pure material after reaction at 50° C. to 180° C., significantly lower than the temperatures reported for other methods. Crystallite sizes between 42 nm and 60 nm are achieved by the novel method, smaller than by other methods. Silver/vanadium atomic ratios of 1.96 to 2.04 in the as-synthesized SVOP result and appear temperature-dependent. Notably, under galvanostatic reduction, the AgVOPOsample with the smallest crystallite size delivers the highest capacity and shows the highest loaded voltage.

Synthetic methods for crystallite size control of bimetallic polyanionic battery compositions

Preparation, characterization, and an electrochemical study of MgVOprepared by a novel sol-gel method with no high-temperature post-processing are disclosed. Cyclic voltammetry showed the material to be quasi-reversible, with improved kinetics in an acetonitrile-, relative to a carbonate-, based electrolyte. Galvanostatic test data under a C/10 discharge showed a delivered capacity &#x3e;250 mAh/g over several cycles. Based on these results, a magnesium anode battery, as disclosed, would yield an average operating voltage &#x2dc;3.2 Volts with an energy density &#x2dc;800 mWh/g for the cathode material, making the newly synthesized material a viable cathode material for secondary magnesium batteries.

The disclosure describes a method of reducing or preventing the growth of microbes on the surface of an object, wherein the object is of such material that it can act as a working electrode. The method comprises the steps of providing a counter electrode, and a reference electrode. The object is used as the working electrode. A first electrical current is passed through the working and counter electrodes. The first current through the counter electrode is varied such that a first electric potential of the working electrode is constant relative to the electric potential of the reference electrode. In some embodiments, a second electrical current is passed through the counter electrode such that a second electric potential of the working electrode is constant relative to the electric potential of the reference electrode.

Electrochemical eradication of microbes on surfaces of objects

A method of synthesizing an electrode material for lithium ion batteries from FeOnanoparticles and multiwalled carbon nanotubes (MWNTs) to yield (FeO-NWNTs) composite heterostructures. The method includes linking the FeOnanoparticles and multiwalled carbon nanotubes using a &#x3c0;-&#x3c0; interaction synthesis process to yield the composite heterostructure electrode material. Since FeOhas an intermediate voltage, it can be considered an anode (when paired with a higher voltage material) or a cathode (when paired with a lower voltage material).

The cell exhibits the typical excellent long-term stability and predictability of the CFsystem, as well as its high energy density (greater than about 300 Ah/cc, greater than about 600 Wh/cc). Additionally, the cell is capable of delivering about 0.5 W/cc of cathode volume for greater than 5 seconds with a voltage above 1.70 V (FIG.).

The gold, iridium, palladium, platinum, rhodium and ruthenium-coated titanium current collector provides the cell with higher rate capability, even after exposure to high temperatures, in comparison to cells of a similar chemistry having the CFcontacted to a titanium current collector painted with a carbon coating.

A new design for a cathode having a configuration of: SVO/first current collector/CF/second current collector/SVO is described. The two cathode current collectors are vertically aligned one on top of the other in a middle region or zone of the cathode. This coincides to where a winding mandrel will be positioned to form a wound electrode assembly with an anode. The overlapping region of the two current collectors helps balance the expansion forces of the exemplary SVO and CFactive material layers. This, in turn, helps maintain a planar cathode that is more amenable to downstream processing. The use of two current collectors on opposite sides of an intermediate cathode active material also provides for enhanced reliability when cathodes are wound from the center as they lend structural integrity to outer portions of the wind.
