An electrosynthesis method for lead used as a negative electrode active material for lead-acid batteries with high electrochemical activity and a conductive network was investigated. The lead was deposited on a conductive carbon felt substrate with a large surface area from various electrolytes by direct and pulse current. The lead deposits were uniform when they were obtained by pulse plating from an electrolyte with a high cathodic overvoltage. The optimun conditions were: 0.1mol·L<sup>-1</sup> Pb (NO<sub>3</sub>)<sub>2</sub>+5.0mol·L<sup>-1</sup> NaOH electrolyte, 0.01s pluse period, 0.5 duty ratio, 50C·cm<sup>-2</sup> cathodic charge density, and 150mA·cm<sup>-2</sup> current density. In this case, utilization of the lead deposits was 37%.
