摘要： A composite material includes a first phase which is present in the form of a plurality of particles comprised of a material having the general formula LixMy(PO4)z wherein M is at least one metal, x is equal to or greater than zero, and y and z are each, independently, greater than zero. The material includes a second phase which is at least partially present in the form of a plurality of elongated filaments which extend between and establish electrical contact with at least two particles of the first phase. The filaments are comprised of a material which includes phosphorus and at least one of the at least one metal M. The material of the second phase has an electrical conductivity which is greater than the electrical conductivity of the material of the first phase. Also disclosed are methods for manufacturing the material. The material has utility as an electrode material for devices such as lithium batteries.

摘要： A composite material which may be used as an electrode for a battery or other electrochemical device, or as a catalyst, has a matrix which is one or more metal carbide, metal nitride, metal boride, metal silicide or intermetallic compound. A metallic component is dispersed in the matrix. The metallic component comprises a metal and an agent which increases the melting point of the metal. The metallic component may be nanodispersed in the matrix. A specific material comprises a nanodispersion of tin, alloyed with an element which increases its melting point to at least 600° C., disposed in a matrix of a transition metal carbide or nitride. This material has very good utility as an anode material for lithium batteries. Also disclosed are other compositions as well as methods for manufacturing the compositions.
