PURPOSE:To improve energy efficiency by using N-methyl N-ethyl piperidinium bromide as a bromin complexing agent. CONSTITUTION:N-ethyl N-ethyl piperidinium bromide is used as a bromine complexing agent. The range of adding volume is used within 0.5mol/l-2mol/l. When the adding volume is not more than thin range, formation ability for a bromine complexing compound is decreased, and self discharge is caused by means of free bromine molecule. Meanwhile, when the adding volume is not less than this range, internal resistance of electrolyte is increased, and energy efficiency is diminished. Thereby, energy efficiency can be improved by proper adding volume.
