  • Publication number: 20110135810
    Abstract: The present invention provides a method of finely depositing lithium metal powder or thin lithium foil onto a substrate while avoiding the use of a solvent. The method includes depositing lithium metal powder or thin lithium foil onto a carrier, contacting the carrier with a substrate having a higher affinity for the lithium metal powder as compared to the affinity of the carrier for the lithium metal powder, subjecting the substrate while in contact with the carrier to conditions sufficient to transfer the lithium metal powder or lithium foil deposited on the carrier to the substrate, and separating the carrier and substrate so as to maintain the lithium metal powder or lithium metal foil, deposited on the substrate.

  • Publication number: 20060057463
    Abstract: Composite compounds of tin and lithium, silicon and lithium, or tin, silicon, and lithium having tin and silicon nano-dispersed in a lithium-containing matrix may be used as electrode materials and particularly anode materials for use with rechargeable batteries. Methods of making the composite compounds include the oxidation of alloys, the reaction of stabilized lithium metal powder with tin and silicon oxides, and the reaction of inorganic salts of lithium with tin and silicon containing compounds.

  • Patent number: 6024892
    Abstract: Anticorrosion and pH-stabilized brine solutions useful for air dehumidification processes are disclosed. Inorganic and organic buffering agents or mixtures thereof can be added to halide solutions of alkali metals, alkaline earth metals, or mixtures thereof, to stabilize the pH and/or minimize corrosion of the dehumidifier system. The solution, with or without additional corrosion inhibitors, can offer improved protection as compared to conventionally used inhibitors during repeated dehumidification cycles. In addition, new corrosion inhibitors are disclosed, such as heteropoly anions and phosphonates, which offer improved corrosion protection in closed or open systems during repeated dehumidification cycles or selected applications. These corrosion inhibitors offer improved protection for metals when used with the buffers disclosed herein.
