AI Customer ServiceTo manufacture a lead acid battery, first, apply the negative paste composition to a grid and dry and cure the paste to form a negative battery plate. Then, assemble a positive battery plate and the negative battery plate to form a green battery. Lastly, convert the tribasic lead sulfate to sponge lead by electrochemical reduction in step 24.
The negative plates in a lead acid battery are made using a composition that includes a polymer mixed with lead oxide, water, an expander, and sulfuric acid. This forms a negative paste composition with the expander and basic lead sulfate crystals having the polymer absorbed on their surfaces. The passage describes a process for reducing active material shrinkage in these batteries.
This chapter reviews of the influence of additives to the pastes for positive and negative plates on the processes of plate manufacture and on the performance of lead–acid batteries. The performance of the lead–acid battery depends on the surface of the active materials of the two types of electrodes.
In the context of lead acid batteries, the negative battery plate comprises a sponge lead negative active mass that exhibits less shrinkage by virtue of the polymer addition. This invention relates to batteries, and more particularly to a paste composition for lead acid batteries.
In the context of this patent, a negative paste is produced by mixing an oxidized lead powder and sulfuric acid with an expander, a polymer and optionally carbon black to produce a paste comprising tribasic lead sulfate crystals, the expander and the polymer.
The corrosion behavior of a commercial Pb-1.7%Sb grid of lead-acid batteries under open circuit conditions in 5 M H 2SO 4 in the presence of phosphoric acid is studied by electrochemical impedance spectroscopy and cyclic voltammetry. Dependence of corrodibility of the alloy on H 3PO 4 concentration is weak up to 0.7M.
