During the past few years, many works have focused on finding a suitable additive to improve the performance of lead-acid batteries [ , , , ]. Traditional organic additives such as derivatives of benzaldehyde , phosphoric acid and amino acids , are generally investigated in the literature.
Phosphoric acid as an electrolyte addictive for lead/acid batteries in electric-vehicle applications Effects of phosphoric acid additions on the behaviour of the lead/acid cell. A Review The effect of phosphoric acid on the positive electrode in the lead acid battery J. Electrochem. Soc., 124 ( 1977), pp. 1478 - 1482
Sulfate-based additives are also employed as electrolyte additive candidates for lead-acid batteries, examples as MgSO 4 and Na 2 SO 4 can not only improve the electrolyte conductivity, reducing battery impedance, but also helpful in increasing hydrogen evolution overpotential of the battery, thus alleviating the water loss [ 21, 22 ].
Recently, the use of ionic liquids in batteries is receiving increasing attention due to their eminent properties; in addition, they have very low environmental impacts . Therefore, this study offers a new strategic approach to improve the performance of lead-acid battery using ionic liquid as electrolyte additives.
