TECHNOLOGY FOCUS - METALLURGY - Preferred Method: The metal is iron, platinum, copper, cadmium, copper, titanium, vanadium, chromium, manganese, nickel, silver, palladium, ruthenium, molybdenum, zirconium, niobium, lanthanum, indium, tin, lead, and/or bismuth.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: Heat treating comprises first heat treatment process conducted under an inert atmosphere; and a second heat treatment process conducted under an oxygen-containing atmosphere. The first heat treatment process is conducted at 300 degrees C to a melting point of a metal included in the coordination polymer. The second heat treatment process is conducted at 300-1500 degrees C. The coordination polymer comprises a compound of formula MxLyS'z.M=metal selected from transition metals, group 13 metals, group 14 metals, group 15 metals, lanthanides, and/or actinides;L=multidentate ligand capable of forming ionic or covalent bonds with greater than or equal to 2 metal ions;S'=monodentate ligand capable of forming an ionic or covalent bond with 1 metal ion;x-z=integers satisfying equation yd+z less than or equal to 6x;andd=number of functional groups of L capable of binding to metal ion.The coordination polymer forms a network by connecting metal ions with the multidentate ligand. The multidentate ligand is selected from trimesate-based ligands of formula (I), terephthalate-based ligands of formula (II), 4,4'-bipyridine-based ligands of formula (III), 2,6-naphthalenedicarboxylate-based ligands of formula (IV), and/or pyrazine-based ligands of formula (V).R1-R25=H atoms; halo atoms; OH; and/or 1-20C alkyl, 1-20C alkoxy, 2-20C alkenyl, 6-30C aryl, 6-30C aryloxy, 2-30C heteroaryl, and/or 2-30C heteroaryloxy (all optionally substituted). EXAMPLE - Nickel (II) acetate tetrahydrate (14.93 g), cobalt (II) acetate tetrahydrate (3.73 g), and trimesic acid (9.98 g) were added to distilled water (500 ml) and stirred at 55 degrees C for 2 hours. Powders produced in the solution were removed using a nylon filter, washed with distilled water multiple times, and then dried at 80 degrees C for 12 hours to obtain a crystalline coordination polymer, which was then subjected to heat treatment under argon atmosphere at 900 degrees C for 1 hour to prepare carbon-(nickel, cobalt) composite. Lithium hydroxide was mixed with the prepared carbon-(nickel, cobalt) composite such that the atom ratio of the transition metal and lithium was 1:1; and the mixture was subjected to heat treatment process at 700 degrees C for 12 hours to prepare porous lithium nickel cobalt oxide (LiNi0.8Co0.2O2) material.
