Directionally oriented particle composites

Magnetostrictive particulate composites with a preferred crystal orientation of the particles and methods for their manufacture are described. In a representative embodiment, a 25% volume Terfenol-D fraction polymer matrix composite was fabricated in a magnetic field using geometric anisotropy to orient needle shaped particles with long axis [112] orientation along the length of the composite. Results demonstrate that the magnetostriction of a [112] oriented particle composite saturates near 1600 ppm. This is a significant increase when compared to composites without preferential orientation (1200 ppm) and represents the largest reported magnetostriction for a particulate composite material.

Multi-phase separated silicon based alloys as negative electrode material for lithium batteries

A particulate composite of silicon, tin, and aluminum (or other suitable metal) is prepared as a negative electrode composition with increased lithium insertion capacity and durability for use with a metal current collector in cells of a lithium-ion battery or a lithium-sulfur battery. This electrode material is formed such that the silicon is present as a distinct amorphous phase in separate matrix phases of crystalline tin and crystalline aluminum. While the distinct tin and aluminum phases provide electron conductivity, each phase accommodates the insertion and extraction of lithium in the operation of the cell and all phases interact in minimizing mechanical damage to the material as the cell experiences repeated charge and discharge cycles. Other suitable metals for use in the composite with silicon and tin include copper and titanium.
