PURPOSE:To provide dendrite inhibitor enabling a battery to operate for longtime with the electrode surface kept smooth, by using a certain heterocyclic 4th class ammonium salt as the effective component. CONSTITUTION:Heterocyclic 4th class ammonium salt as indicated in the general formula, such as methylalkylpyrrolidiniumhalide, methylalkylmorpholiniumhalide, and methylalkylpiperidiniumhalide, was added to 100ml of electrolyte several mg to several hundred mg. While using a water solution of 3mol/l of zinc bromide as the electrolyte for the cathode, charging was carried out with the current density at 20, 40, 60 and 80mA/cm<2> and the charged quantity of electricity of 360mAh/cm<2>, with the result that electrodeposition of zinc on the cathode surface was extremely smooth. The result was highly remarkable with current density of 20-60mA/cm<2>. |
