NOVELTY - A nickel based alkali secondary battery preparation method involves preparing a raw material. The mixture is placed in ball milling uniformly mixed to obtain raw material powder. Anode material slurry is prepared, the powder is transferred to a stirring machine, and deionized water, PTFE emulsion and carboxy methylated cellulose as thickening agent are added to the powder and stirred. The anode slurry is coated, dried followed by coating on a foam nickel collector in a single-faced manner, grinding to form an electrode sheet, and shearing sheet with predetermined size.    USE - Method for preparing nickel based alkali secondary battery.    ADVANTAGE - The prepared battery has high cell capacity, improved discharge property and prolonged service life.    DETAILED DESCRIPTION - A nickel based alkali secondary battery preparation method involves preparing a raw material, where the raw material comprises nano graphite powder conductive agent (5-8%), a carbon nano tube (1-3%), yttrium oxide (1-2%), calcium hydroxide, powder crystal of a super capacitor material such as cobalt aluminum hydroxide (CoAl(OH)4) (10-20%), binding agent such as polyvinylidene fluoride, and the balance of an anode active material (5-10%) such as nickel aluminum hydroxide (Ni4Al(OH)10)OH. The mixture is placed in ball milling for 2-3 hours, uniformly mixed using 300-mesh sieve to obtain raw material powder. Anode material slurry is prepared, the screened anode raw material powder is transferred to a stirring machine, and deionized water (30-40%), PTFE emulsion (10-20%) and carboxy methylated cellulose (5-10%) as thickening agent are sequentially added to the anode raw material powder and stirred at speed of 40 rpm for 30 minutes to obtain the anode material slurry. The anode slurry is coated, dried and cut by intermittent coating process followed by coating on a foam nickel collector in a single-faced or two-faced manner, grinding to form an electrode sheet, and after drying, shearing the electrode sheet with a predetermined size.
