    Abstract: A non-aqueous electrolyte secondary battery containing an alloy particle capable of absorbing and desorbing lithium in the negative electrode has a short cycle life and is insufficient in high-rate discharge characteristics, since the alloy particle is pulverized during charge/discharge cycles. In order to solve this problem, a negative electrode is employed, which comprises an alloy particle containing: at least two selected from the group consisting of metal elements and semimetal elements; oxygen; and nitrogen. It is preferred that the alloy particle have a phase A capable of electrochemically absorbing and desorbing lithium ion and a phase B having lithium ion conductivity or lithium ion permeability and that the phase B contain larger amounts of oxygen and nitrogen than the phase A.

    Abstract: Methods of fabricating objects using additive manufacturing are provided using pretreated powders. In a first aspect, the methods create in situ dispersoids within the object to increase the oxygen content to between 500 ppm and 3000 ppm or to increase the nitrogen content to between 250 ppm and 1500 ppm. The pretreated powders are then formed into layers in an environmentally controlled chamber of an additive manufacturing machine. The quantity of refractory alloy powder is partially pretreated by exposure to the atmosphere for a selected period of time or in an inert atmosphere having oxygen and/or nitrogen introduced thereinto. The partially pretreated quantity of powder is then further pretreated in an inert atmosphere controlled chamber to raise the oxygen and/or nitrogen level to between about 250 ppm and 1000 ppm for nitrogen and between about 500 ppm and 2000 ppm for oxygen. The layers of pretreated powder are then exposed to a transient moving energy source or stationary energy source for melting and solidifying the layers; and creating in situ dispersoids in the layers. In a second aspect, carbon dioxide is introduced into an inert atmosphere controlled chamber having hafnium powder therein for creating hafnium carbide dispersoids throughout the object.
