Expanders, as lignosulfonates, are crucial for a good performance of Pb/acid batteries. In the process of discharge, the Pb and the PbO 2 go to PbSO 4.The formed PbSO 4 is adsorbed on the surface of the Pb electrode and dramatically reduces the lifetime of the battery by the formation of big PbSO 4 crystals. In order to prevent that, the addition of expanders in the

Organic expanders are an indispensable component of the paste recipes for lead–acid battery negative plates. These substances regulate the processes involved in the formation of the structure of the lead active mass during manufacture of the negative plates. which is an evidence of the correlation between the content of the given
Expanders are an essential component of lead/acid batteries. They prevent performance losses in negative plates that would otherwise be caused by passivation and structural changes in the active material.
This study investigates the influence of the organic expander component (Vanisperse A) and of BaSO 4 on the performance of negative lead-acid battery plates on high-rate partial-state-of-charge (HRPSoC) cycling. Batteries operating in the HRPSoC mode should be classified as a separate type of lead-acid batteries.
A battery expander is a mixture of barium sulfate, carbon, and a lignosulfonate or other organic material that is added to the negative plate active material during battery preparation. It may also incorporate other known ingredients, such as wood flour and soda ash, to improve the battery's performance.
A lead-acid battery is a kind of rechargeable cell commonly used as a cars power source . To improve the chargeacceptance and the general performance of the lead-acid batteries, the use of an expander is essential [51, 52] .
This is because the battery industry is pursuing improvements to existing products and is developing new products for emerging markets such as electric and hybrid electric vehicles. 9. Conclusions Battery manufacturers use a number of methods to add expander to negative paste mixes.
Specifically, in valve regulated lead-acid batteries for hybrid electric vehicles, the improved expander formulations include approximately 0.2% to 6% graphite or mixture of carbon and graphite, and preferably approximately 1% to 5%. In particular, improved expanders having approximately 1% to 3% graphite is preferred.
