Abstract

The invention discloses anode lead plaster of power lead-acid storage battery polar plate, and the anode lead plaster comprises the following components in proportion by weight: 1000 lead powder, 1.5 to 4 antimonous oxide, 0.8 to 1.8 stannous mono-sulphate, 1 to 2.5 aquadag, 0.68 to 0.8 conductive fiber, 25 to 40 lead tetraoxide, 80 to 96 dilute sulfuric acid and 1 to 4 silicon dioxide. The gas-phase silicon dioxide capable of increasing the viscosity strength of active substances and the conductive fiber capable of enhancing the conductive capacity of the polar plate are added, an optimum effect can be reached by adjusting the proportion of the two additives and other additives, so that under the situation of identical mass of the active substances and identical structure of a grid, the circulation service life of a power lead-acid storage battery can be improved by 28 percent, and the battery capacity of the power lead-acid storage battery can be improved by 10 to 15 percent.

Description

technical field [0001] The invention relates to the field of lead-acid storage batteries, in particular to a positive lead paste for a lead-acid storage battery plate for power. Background technique [0002] The lead-acid battery was invented by the Frenchman Plante in 1859. It has a history of more than 100 years. It has made great progress in the theoretical research of lead-acid batteries, product types and varieties, and product electrical properties. . [0003] Since the invention of the lead-acid battery, due to its low price, easy access to raw materials, sufficient reliability in use, suitable for large current discharge and wide ambient temperature range, etc., it has always occupied an absolute advantage in chemical power sources, whether it is in Lead-acid batteries play an indispensable and important role in transportation, communication, electric power, military or in various fields of navigation and aviation. [0004] The main components of the lead-acid batt...
