NOVELTY - An ultra-high temperature alkaline secondary nickel(Ni)/metal hydride(MH) battery is manufactured by adding macro molecule fluoride depressor into anode material of battery, properly adding carbonyl metal oxide into cathode material, adding stabilizer into electrolyte, and using acrylonitrile butadiene styrene (ABS) modified polymer for battery shell.    USE - An ultra-high temperature alkaline secondary Ni/MH battery.    ADVANTAGE - The battery can discharge at 80 degrees C ultra-high temperature, thus promoting discharging performance.    DETAILED DESCRIPTION - An ultra-high temperature alkaline secondary Ni/MH battery is manufactured by:    (A) producing positive plate by placing 68-92 wt.% nickel hydroxide (Ni(OH)2), 1-4 wt.% additive, 2-8 wt.% depressor and 5-20 wt.% binder, into tempering machine and manufacturing them to be cream-shape material, then coating cream-shape material on conductive matrix, drying and rolling, cutting into demanded size, and welding pole ear;    (B) producing negative plate by placing 70-92 wt.% storage alloy powder, 1-4 wt.% additive, 2-8 wt.% carbonyl metal oxide and 5-18 wt.% binder into tempering machine and manufacturing them to be cream-shape material, then coating cream-shape material on conductive matrix, drying and rolling, cutting into demanded geometry size, and welding pole ear;    (C) producing shell, cover by drying and mixing 60-80 wt.% ABS and 20-40 wt.% PVC, utilizing as raw material of injection molding battery shell, cover, using plastic jetting-molding machine and injection molding module to process battery shell, where the battery shell has good weathering resistance, good mechanical performance, and long anti-aging time;    (D) preparing electrolyte by adding 0.5-2 wt.% M stabilizer into electrolyte with d=1.2-1.3 g/mL prepared through 6 N potassium hydroxide (KOH) and 0.5 lithium hydroxide (LiOH) and de-ionized water, mixing to dissolve and cooling off for more than 24 hours;    (E) producing battery pole pile, according to number of plate of demanded capacity, separating prepared positive, negative plate using homemade insulated paper, connecting pole ear to pole column after superposing, then placing it into shell;    (F) injecting electrolyte by adding prepared electrolyte one by one into battery shell according to 2-6 mL/Ah; and    (G) cementing or welding special adhesive of battery cover onto battery shell.
