The invention provides a preparation method of a high-performance EFB start-stop battery. A formula of positive lead paste comprises 70Kg of lead powder, 4Kg of dilute sulphuric acid, 12Kg of pure water, 0.06 Kg of polyester fiber, 0.01-0.15 Kg of silicon dioxide and 0.25 Kg of sodium perborate; the formula of the negative electrode lead paste comprises 70 Kg of lead powder, 2.5 Kg of dilute sulphuric acid, 13 Kg of pure water, 0.1 Kg of humic acid, 0.15 Kg of lignin solution, 0.6 Kg of barium sulfate, 0.01-1 Kg of super carbon black, 0.01-0.8 Kg of graphite and 0.01-0.3 Kg of bismuth trioxide. The positive and negative lead paste formulas are adjusted to generate a synergistic effect, so that the water loss and charging acceptance of the battery reach a balanced state, and the service life of the battery is prolonged. 本申请提供一种高性能EFB起停电池制备方法，正极铅膏配方：铅粉70Kg、稀硫酸4Kg、纯水12Kg、聚酯纤维0.06Kg、二氧化硅0.01-0.15Kg、过硼酸钠0.25Kg；负极铅膏配方：铅粉70Kg、稀硫酸2.5Kg、纯水13Kg、腐植酸0.1Kg、木素溶液0.15Kg、硫酸钡0.6Kg、超级炭黑0.01-1Kg、石墨0.01-0.8Kg、三氧化二铋0.01-0.3Kg。即调整正
