USE - 12-TKMA-150 type high energy sealed lead acid storage battery for T-90 tank.    ADVANTAGE - The battery has large capacity of 150 ampere-hours.    DETAILED DESCRIPTION - A 12-TKMA-150 type high energy sealed lead acid storage battery for T-90 tank comprises battery shell, battery cover, deflective post, positive plate grid, negative plate grid, plastic frame, and electrolyte. The battery has size of 460x 236x 236 mm. The positive plate grid comprises alloy material comprising (kg) Pb alloy (100), Ca (80-120), Al (10-50), Cu (10-50), Sn (300-1000) and Se (5-50). The positive plate grid alloy material is melted in a lead melting furnace, and cast in a positive plate grid mold to fabricate the positive plate grid. The positive plate of the positive plate grid is prepared by adding sulfuric acid solution (10-15 L) with specific gravity of 1.25 g/cm3, conductive fiber (100-800 g), cobalt sulfate (100-600 g), and Picconol A500(RTM: resin emulsion) (100-800 g) into lead powder (100 kg); uniformly stirring mixture; coating the mixture on the positive plate grid; and curing, shaping and drying. The negative plate grid comprises alloy material comprising (kg) Pb alloy (100), Ca (50-150), Al (10-50), Cu (10-60), bismuth (50-150), Se (10-50) and Sn (300-1200). The negative plate grid alloy material is melted in a lead melting furnace, and cast in a negative plate grid mold to fabricate the negative plate grid. The negative plate of the negative plate grid is prepared by adding sulfuric acid solution (10-15 L) with specific gravity of 1.25 g/cm3, barium sulfate (600-800), humic acid (300-800), conductive fiber (100-800), Lignosol TSD(RTM: ammonium lignin sulfonate) (100-900), Alkanol XC(RTM: anionic surfactant) (100-800) and alpha and beta naphthoic acid (300-600); uniformly stirring the obtained mixture; coating the mixture on the negative plate grid; and curing, shaping and drying. The plastic frame has thickness of 0.4 mm and width and height respectively the same as that of the positive plate. The adhesive is coated on two sides of the plastic frame, and two pieces of positive plates are adhered to the two sides to fabricate a positive plate with a gap of 0.4 mm in the middle and two positive plates on two sides. The gap of 0.4 mm is filled with colloidal electrolyte having 6.8% gel content. A number of positive plates and a number of negative plates are welded together with a membrane between every pair of positive and negative plates through a bus bar to fabricate a plate group. Twelve plate groups are packaged in the shell of the battery, where the plate groups are connected with the deflective post. The shell of the battery is sealed with a battery cover, and filled with electrolyte. The electrolyte comprises sodium phosphate (100-500 g), sodium sulfate (10-100), and sulfuric acid solution (100 kg) with specific gravity of 1.3-1.34 g/cm3.
