Said invention refers to reducing power type column sealed zinc nickel alkaline accumulator internal pressure method. It features after processing superfine graphite or active carbon, using 0.5-5 per cent sodium polyacrylates aqueous solution to make colloidal graphite or active carbon emulsion, then spray coating on zinc cathode surface, after drying assembling with relevant nickel electrode and diaphragm to power type column sealed zinc nickel alkaline accumulator. Said invented method made accumulator has not gas and liquid leakage through different multiplying factor charge and discharging and service life circulation by more than 100 times.
