Claim 15:
16. A method for preparing a battery separator of a rechargeable battery, the method comprising:
processing a nanowire slurry comprising dihydroxyaluminum sodium carbonate nanowires and water, including preparing the nanowires by a hydrothermal growth process;
wherein the hydrothermal growth process comprises:
adding deionized water, sodium bicarbonate and sodium hydroxide to a blender and blended to form a solution;
adding sodium hydroxide to the solution to adjust the pH of the solution to be in a range from 10 to 11;
adding aluminum isopropoxide and blended to form a slurry;
transferring the slurry into a pressure vessel;
heating the pressure vessel to an elevated temperature for 12 to 96 hours; and
cooling the pressure vessel to room temperature, and producing the dihydroxyaluminum sodium carbonate nanowires;

wherein the nanowire slurry is prepared by milling the dihydroxyaluminum sodium carbonate nanowires and water through a three roll mill.
