Abstract

The invention discloses a cathode lead plaster formula, which comprises the following components in percentage by weight: 80 to 85 percent of lead powder, 7 to 9 percent of deionized water, 7 to 10 percent of 45 mass percent sulfuric acid solution, 0.05 to 0.1 percent of conductive fiber, 0.5 to 1 percent of barium sulfate, 0.1 to 0.3 percent of lignin and 0.1 to 0.2 percent of humic acid. The formula has the advantages that: the internal resistance of a battery with the same structure is reduced by 10 percent by using the lead plaster, the n value in a 2-hour rate Peukert formula is less than 1.20, and the capacity discharged at high current is not greatly reduced.

Description

A kind of cathode lead plaster prescription

Technical field

The present invention relates to a kind of cathode lead plaster prescription.

Background technology

The composition of the paste spread type negative plate of preparation lead acid accumulator generally comprises at present: lead powder, water, sulfuric acid solution, can add such as various additives such as short fiber, barium sulfate, acetylene black, carbon black, humic acid, lignins, can cause the internal resistance of storage battery bigger with short fiber as the adhesion that additive increases between the lead plaster, the capacity of emitting during heavy-current discharge declines by a big margin, be that the Peukert resistance is bigger, such pole plate is relatively poor in the application power of motive-power battery.

Summary of the invention

The object of the present invention is to provide a kind of cathode lead plaster prescription, can effectively solve existing motive-power battery and make the problem that cathode lead plaster causes the battery applications ability as additive with short fiber.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of cathode lead plaster prescription, comprise following component, the each component percentage by weight is: lead powder 80～85%, deionized water 7～9%, the sulfuric acid solution 7～10% of mass percent concentration 45%, conductive fiber 0.05～0.1%, barium sulfate 0.5～1%, lignin 0.1～0.3%, humic acid 0.1～0.2%.

Preferably, the each component percentage by weight is: lead powder 80%, deionized water 9%, the sulfuric acid solution 10% of mass percent concentration 45%, conductive fiber 0.1%, barium sulfate 0.6%, lignin 0.1%, humic acid 0.2%; Reach the cathode lead plaster prescription of optimum performance.

Preferably, the each component percentage by weight is: lead powder 85%, deionized water 7%, the sulfuric acid solution 7% of mass percent concentration 45%, conductive fiber 0.07%, barium sulfate 0.5%, lignin 0.3%, humic acid 0.13%; The cathode lead plaster prescription of optimality price ratio.

Preferably, the each component percentage by weight is: lead powder 83%, deionized water 8%, the sulfuric acid solution 8% of mass percent concentration 45%, conductive fiber 0.05%, barium sulfate 0.65%, lignin 0.2%, humic acid 0.1%; Most economical cathode lead plaster prescription.

Preferably, described conductive fiber is the polyacetylene fiber, polypyrrole fiber, at least a in the polythiophene fiber; Conductive fiber with excellent conductive performance.

Compared with prior art, advantage of the present invention is: the battery of same structure, use lead plaster of the present invention, and the internal resistance of battery has reduced n value in 10%, the 2 hour rate Peukert formula less than 1.20, and the capacity of emitting at big electric current also has no substantial decline.
