Abstract

The invention discloses a tubular negative plate of a lead-carbon battery. The negative plate comprises a negative plate grid and filled active substance powder, wherein the negative plate grid is of a fence structure consisting of transverse beams and conductive cores perpendicular to the transverse beams; a sleeve layer is arranged outside the negative plate grid; the gaps among the sleeve layer and the conductive cores is filled with the active substance; the active substances consist of the following substances in percentage by weight: 57-95% of lead powder, 1-40% of a capacitive carbon material, 0.1-0.5% of carbon black, 0.3-2% of barium sulfate, 0-1.2% of sodium lignin sulfonate, 0.5-2% of humic acid, 0.05-0.1% of short fiber. The tubular negative plate of the lead-carbon battery is simple in manufacturing process and easy to realize, a diachylon structure is stabilized and prevented from dropping off, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a tubular negative plate of a lead-carbon battery. Background technique [0002] With the increasingly prominent oil shortage and urban environmental problems, vigorously developing the new energy industry and the electric vehicle industry has become two important issues facing the sustainable development of the national economy. As a device for energy storage and conversion, the secondary power supply has become the key to restricting the development of these two industries. Lead-acid batteries have experienced nearly 150 years of development. They have the advantages of abundant raw materials, good safety and reliability, high cost performance, and recyclability. They occupy an important position in the field of secondary power sources. Lead-acid batteries have played an indispensable and important role in various economic fields such as transportation, communicati...
