PURPOSE:To improve the recovery charging characteristic and provide a trait to sustain with overdischarge and being left as it is for a long time, by adding quarternary ammonium ions. CONSTITUTION:With co-existence of quarternary ammonium having common ion as SO, a weak electrolytic PbSO4 reduces its electric dissociativeness, and the concentration of Pb<2+> is suppressed. That is, the electric dissociativeness (concentration of Pb<2+>) of PbSO4 is invertedly proportional to the concentration of the quaternary ammonium ions added. Accordingly admission of charging is improved by adding tetraethyl-ammonium ions or tetramethyl-ammonium ions as quaternary ammonium ion to the electrolyte. Even under long-term left condition and charge condition, existence of the quarternary ammonium ion has good effect. |
