The selection lead-acid battery took the research object, in view of lengthens the service life this key question, in the development electrolyte the chemical additive to the lead-acid battery performance influence. Uses the sufficient electric discharge method, records makes the under battery sufficient discharging curve in the chemical additive. Screens 6 kind of chemical additives (N1-N6), has conducted the sufficient electric discharge experimental condition research, the research chemical additive function. Uses in the electric conductance monitor solution the density change, determined differently circulates under the sufficient electric discharge condition battery capacity. Simultaneously has carried on the compound supplement (M1-M3) battery sufficient electric discharge behavior research, research supplement to battery capacity influence. The experimental result indicated that, Transition metal compound N1 and N2 have the important influence to the sufficient discharging curve, can eliminate the lead-acid battery the sulfuric acid salt chemicals, reduces the battery the capacity weaken, lengthened the battery the service life, compound M1 and M2, M1 chemical additive arrives the certain negative to the battery but M2, the M3 effect has been very good in the certain degree prevents the lead-acid battery sulfate to conceal reduces the battery the capacity weaken, lengthened the battery the service life .
