[0282] Example 1 - Laser pyrolysis synthesis of related powders using aerosols

[0283] This example presents the synthesis of lithium nickel cobalt oxide by laser pyrolysis using aerosols. Laser pyrolysis is used essentially as figure 1 , 3 and the reaction chamber described in 4.

[0284] Lithium nitrate (LiNO 3 ) (99%, 1.1 moles), (Ni(NO 3 )x6H 2 O) (technical grade, 0.7 mole) and (Co(NO 3 )x6H 2 O) (ACS grade, 0.2 mol) precursor was dissolved in deionized water. Aluminum nitrate precursor was obtained from Alfa Aesar Inc., Ward Hill, MA. The solution was stirred on a hot plate using a magnetic stirrer. The aqueous metal precursor solution is injected into the reaction chamber as an aerosol. Will C 2 h 4 Gas is used as the laser absorbing gas, and nitrogen is used as the inert diluent gas. will contain metal precursors, N 2 , O 2 and C 2 h 4 The reactant mixture is introduced into the reactant nozzle for spraying into the reaction chamber. In Table 1 other...

Abstract

Light reactive deposition can be effectively used to deposit one or more components of an electrochemical cell. In particular, electrodes, electrolytes, and electrical interconnects can be deposited from reactive flow. In certain embodiments, the reactant flow includes a reactant stream that intersects the light beam to drive a reaction in the photoreaction zone to produce a product deposited on the substrate (422). This method is extremely versatile for making a variety of compositions useful especially in electrochemical cells and fuel cells. The properties of the material, including density and porosity, can be adjusted based on the deposition properties and any subsequent treatment including, for example, heat treatment.
