“…They can be designed easily by changing the type of anion or cation. Recently, one of their most promising applications is the enhancement of electrochemical performance of power devices [20][21][22][23]. Due to their electrochemical stability, ILs are widely used as electrolytes, especially in lithium-ion batteries or supercapacitors [24][25][26].…”

The influence of selected types of ammonium ionic liquid (AIL) additives on corrosion and functional parameters of lead-acid battery positive electrode was examined. AILs with a bisulfate anion used in the experiments were classified as protic, aprotic, monomeric, and polymeric, based on the structure of their cation. Working electrodes consisted of a lead-calcium-tin alloy utilized in the industry for manufacturing current collectors of positive electrodes in lead-acid batteries (LABs). This alloy was used in the first part of the study for the evaluation of corrosion intensity and stability of electrolyte with AIL additives. In the second part, the grid made of the examined alloy was covered with positive active mass, the composition of which was modified by selected AIL. The selection of an appropriate substance was made based on parameters such as corrosion potential, corrosion current, polarization resistance, and hydrogen and oxygen evolution potentials. Techniques such as linear sweep voltammetry, corrosimetry, and electrochemical impedance spectroscopy were used. The conducted measurements revealed that polymeric AIL additive had an exceptionally positive influence on the inhibition of the corrosion process in LAB and electrochemical window of the electrolyte. The influence of this compound on the specific capacity and resistance of the active mass was also discussed.

“…The carbon-lead oxide paste electrode was prepared via mixing 50:50% (w/w) graphite with lead oxide powder [7], washed with diethyl ether and dried under vacuum, which was then mixed with the appropriate amount of mineral oil with thorough hand mixing in a mortar and pestle. The paste was then packed into the end of a glass tube (approx.…”

“…Electrolyte composition and additives are other important parameters which affect the overpotential of water decomposition. Therefore, plenty of studies are reported on the effect of some material additives in the lead alloy grids, such as Sb, Ca and Se [4][5][6], and of using of H 3 PO 4 and other electrolyte additives on the performance of lead acid batteries [7]. Although antimony is the most popular additive in lead alloy grids, it mainly decreases the overpotential of hydrogen evolution at the negative plate.…”

In this work, the application of ionic liquids (ILs)-mono-, bicycyclohexyl, monohexyl and tetrahexyl ammonium hydrogen sulphate-as electrolyte additives on the electrochemical performance of lead acid batteries is proposed. The electrochemical behaviour of Pb-1.66% Sb-0.24% Sn alloy in sulphuric acid solution is investigated in the presence of the mentioned ILs with different numbers of alkyl or cycloalkyl chains. Particularly, the hydrogen and oxygen evolution potential and anodic layer characteristics were studied using cyclic and linear sweep voltammetric methods. The obtained results indicate that hydrogen evolution overpotential of Pb/Sb/Sn alloy in the presence of ILs increases. This overpotential mainly depends on the concentration of ILs and the number of alkyl and cycloalkyl chains on the cations. Also, the difference between the oxygen oxidation potential in anodic and cathodic scans (ΔE) decreases using different ILs.

“…It concerns classic inorganic additives (phosphoric acid, boric acid, citric acid, strontium sulphate, sodium sulphate), carbon suspensions and organic polymer emulsions. At the present, the great potential of ionic liquids as electrolyte additives is actively studied [17] due to the capacity of these salts to widen the electrochemical window of water [18], [19] and [20]. Also of great practical interest is the study of additives that produce gelled electrolytes, due to their applications in the field of electric locomotion [21], [22] and [23].…”

Abstract:The paper presents a method to assess the effect of electrolyte additives on the energy capacity of Pb-acid batteries. The method applies to any chemically unreactive additive, including suspensions and gels. The approach is thermodynamically based and it leads to the definition of a region of admissible concentrations -the battery's admissible range-where the battery can undergo an indefinite number of charge/discharge cycles without suffering permanent damage. An experimental procedure to determine this range is presented. The obtained results provide a way to assess the potential of electrolyte additives to improve the energy capacity of Pb-acid batteries. The same results also provide a means to determine the additive concentration that produces the maximum energy capacity increase of the battery. The paper closes with an example of application of the proposed approach to a practical case.
