Abstract

A lead paste for negative electrode of carbon gel battery is prepare from dilute sulfuric acid, deionized water, short fiber, carboxymethyl cellulose, sodium lignosulfonate, barium sulfate, silicon dioxide, carbon fiber and lead powder. The invention also discloses a preparation method of carbon gel battery negative electrode lead paste. As that carbon fib is added into the negative electrode leadpaste formulation, the conductivity of the carbon gel battery is effectively improve, and the large current discharge and charging acceptance ability are improved. Silica acts as a stationary liquidin the composition, which causes the electrolyte to be encapsulated in the colloid of the three-dimensional system, thus delaying the water loss of the battery. The invention has the advantages of reasonable component configuration, obvious performance improvement of the negative electrode lead paste, preparation under conventional conditions and easy industrial production.

Description

technical field [0001] The invention belongs to the technical field of electrochemical power sources. Specifically, the invention relates to a formula and a preparation method of key components of a series of lead-acid batteries, especially a formula and a preparation method of a carbon-glue battery negative electrode paste. Background technique [0002] With the pace of the times, the research and development capabilities and research and development conditions of this industry have generally been improved. In recent years, a number of technical improvements have been made to the traditional lead-acid batteries, making their performance a new level. For example, by adding a certain amount of carbon material to the negative electrode paste of the lead-acid battery, the electrical performance of the battery can be effectively improved. Such products are commonly called lead-carbon batteries in the industry. Carbon material is a kind of traditional basic material, which has hi...
