The aim of the presented work was to improve the lifetime of lead-acid SLI (starting, lighting and ignition) batteries through electrolyte modification with ionic liquids. The conducted research included the synthesis and determination of the influence of di(hexadecyldimethylammonium) and di(octadecyldimethylammonium) sulphates on the basic parameters (capacity, cranking performance) of the starter battery as well as parameters affecting its lifetime (dynamic charge acceptance, corrosion, water consumption). It has been shown that the addition of these compounds increases corrosion resistance and reduces water consumption, resulting in an increase in cyclic durability by up to 36%. The improvement is associated with the absorption of ionic liquid molecules into the mass of lead(ii) sulphate, which was confirmed by physicochemical and electrochemical studies.
本研究的目的是通过用离子液体对电解液进行改性来提高铅酸启动、照明和点火（SLI）电池的使用寿命。所进行的研究包括合成二（十六烷基二甲基铵）硫酸盐和二（十八烷基二甲基铵）硫酸盐，并测定其对启动电池基本参数（容量、启动性能）以及影响其使用寿命的参数（动态充电接受能力、腐蚀、水消耗）的影响。结果表明，添加这些化合物可提高耐腐蚀性并减少水消耗，从而使循环耐久性提高多达36%。这种改善与离子液体分子吸收到硫酸铅物质中有关，这已通过物理化学和电化学研究得到证实。
