Title: Iron-based composition for magnetocaloric effect (MCE) applications and method of making a single crystal

Abstract

A method of making a single crystal comprises heating a material comprising magnetic anisotropy to a temperature T sufficient to form a melt of the material. A magnetic field of at least about 1 Tesla is applied to the melt at the temperature T, where a magnetic free energy difference .DELTA.G.sub.m between different crystallographic axes is greater than a thermal energy kT. While applying the magnetic field, the melt is cooled at a rate of about 30.degree. C./min or higher, and the melt solidifies to form a single crystal of the material.

Method of making nanostructured lithium iron phosphate—based powders with an olivine type structure

Patent Singhal, Amit; Skandan, Ganesh

A low cost and scalable processes for producing nanostructured LiFexM1-xPO4 and nanostructured LiFexM1-xPO4/C composite powders, where 1≦x≦0.1 and M is a metal cation, such as Mn, Co, Ni, and V. Electronics made of either nanostructured LiFexM1-xPO4 powders or nanostructured LiFexM1-xPO4/C composite powders exhibit good electrochemical properties. The electronic conductivity of nanostructured LiFexM1-xPO4 powders is enhanced by intimately mixing them with ultrafine carbon particles. Thus, the use of nanostructured LiFexM1-xPO4/C composite powders will lead to high power density, low cost and environmentally friendly rechargeable Li-ion batteries.
