High Capacity Anode Materials for Lithium Ion Batteries
High capacity silicon based anode active materials are described for lithium ion batteries. These materials are shown to be effective in combination with high capacity lithium rich cathode active materials. Supplemental lithium is shown to improve the cycling performance and reduce irreversible capacity loss for at least certain silicon based active materials. In particular silicon based active materials can be formed in composites with electrically conductive coatings, such as pyrolytic carbon coatings or metal coatings, and composites can also be formed with other electrically conductive carbon components, such as carbon nanofibers and carbon nanoparticles. Additional alloys with silicon are explored.

Process for the electrolytic deposition of metal layers

PCT No. PCT / EP96 / 05140 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Nov. 21, 1996 PCT Pub. No. WO97 / 19206 PCT Pub. Date May 29, 1997The invention relates to a method for the electrolytic deposition of metal coatings, in particular of copper coatings with certain physical-mechanical and optical properties and uniform coating thickness. According to known methods using soluble anodes and applying direct current, only uneven metal distribution can be attained on complex shaped workpieces. By using a pulse current or pulse voltage method, the problem of the coatings being of varying thickness at various places on the workpiece surfaces can indeed be reduced. However, the further problem of the geometric ratios being changed continuously during the depositing process by dissolving of the anodes is not resolved thus. This can be avoided by using insoluble anodes. In order to guarantee sufficient stability of the anodes and a bright coating even at those points on the workpiece surfaces, onto which the metal is deposited with high current density, it is essential to add compounds of an electrochemically reversible redox system to the depositing solution.

UV curable and electrically conductive adhesive for bonding magnetic disk drive components
An electrically conductive adhesive includes a resin component, a photoinitiator, and metal-coated polymer beads. The beads have an average diameter and a very narrow size distribution around the average diameter. The adhesive is applied between a read / write head and a suspension to attach the two, and the adhesive is cured by exposure to an illumination and / or heat. A pad spacer is included between the read / write head and the suspension to define a spacing and parallelism therebetween. The beads in the adhesive can form one or more layers between the read / write head and the suspension or can be disordered. The metal coating of the beads provide electrical conductivity between the read / write head and the suspension.

Power and ground planes used in Printed Circuit Boards (PCBs) having porous, conductive materials allow liquids (e.g., water and / or other solvents) to pass through the power and ground planes, thus decreasing failures in PCBs (or PCBs used as laminate chip carriers) caused by cathodic / anodic filament growth and delamination of insulators. Porous conductive materials suitable for use in PCBs may be formed by using metal-coated organic cloths (such as polyester or liquid crystal polymers) or fabrics (such as those made from carbon / graphite or glass fibers), using metal wire mesh instead of metal sheets, using sintered metal, or making metal sheets porous by forming an array of holes in the metal sheets. Fabrics and mesh may be woven or random. If an array of holes is formed in a metal sheet, such an array may be formed with no additional processing steps than are performed using conventional PCB assembly methods.

Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and / or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.
