TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metal is in the form of fluorinated titanic acid or fluorinated zirconic acid.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The surface treatment layer contains 1-200/m2 (I), 0.5-50 mg phosphoric acid compound (in terms of phosphorus) and 0.5-50 mg metal/m2, based on its total solid content. The outer protective layer comprises stretched polyester-based resin and/or stretched polyamide resin. The modified adhesive resin layer is made of maleic anhydride or phthalic acid grafted olefin polymers. The modified adhesive resin layer further comprises 5-50 wt.% ethylene-propylene copolymer or ethylene-propylene-diene monomer terpolymer, based on total solid content. The barrier resin layer comprises at least 50 wt.% thermoplastic elastomers, based on total solid content, and further comprises 5-50 wt.% olefin-based resin including polypropylene, ethylene-propylene copolymer and/or propylene-1-butene-ethylene copolymer. The heat sealing resin layer comprises olefin-based resin including polypropylene, ethylene-propylene copolymer and/or propylene-1-butene-ethylene copolymer. Preferred Method: The surface treatment layer is formed by coating the composition by dip-coating, spray coating, bar coating or roll coating to 1-200 mu m thickness and drying at 80-250 degrees C. The inner sealant layer and barrier layer or surface treatment layer are bonded by thermal lamination or T-die co-extrusion. EXAMPLE - 24.6 g Polyvinyl phenol resin with average molecular weight of 5000 was heated in 54.5 g 1-propoxy-2-propanol, 40.4 g N-methylglucamine was added to the obtained resin solution, heated to 60-65 degrees C, then 16.6 g 37% aqueous formaldehyde solution was added, heated to 90 degrees C and reacted.The resultant solution was diluted with deionized water so that the solid content was about 10 wt.% to obtain polyvinyl phenol-N-methylglucamine Mannich addition product. 3 wt.% Phosphoric acid solution, 6 wt.% hexafluorozirconic acid solution and 6 wt.% hexafluorotitanic acid solution were added to the addition product and mixed with 1l water to obtain aqueous surface treatment solution. The aqueous surface treatment solution was coated on both sides of 40 mu m soft degreased aluminum foil using bar coater and dried at 150 degrees C to form surface treatment layer. Then polyurethane adhesive was applied on one surface of a surface treatment layer by dry lamination and then 25 mu m biaxially stretched nylon film was adhered to form protective layer and unstretched polypropylene film of 30 mu m and acid-modified polypropylene resin were applied on the other surface of surface treatment layer obtain the battery packaging material.
