There is disclosed a cyclic process for producing taurine from monoethanolamine comprising the steps of: (a) reacting monoethanolamine with ammonium sulfate in the recycling mother liquor to yield monoethanolamine sulfate; (b) reacting the monoethanolamine sulfate with sulfuric acid to form 2-aminoethyl hydrogen sulfate ester; (c) subjecting the 2-aminoethyl hydrogen sulfate ester to a sulfonation reaction with ammonium sulfite to yield taurine and ammonium sulfate; (d) separating the taurine and the ammonium sulfate by means of solid-liquid separation; (e) removing the excess ammonium sulfite from the mother liquor to obtain an aqueous solution comprised of ammonium sulfate and (f) returning the aqueous solution to step (a) to complete the cyclic process.

Disclosed is an electrolyte and a secondary battery containing the same. According to the present disclosure, charging efficiency and output may be improved due to low discharge resistance, and gas generation and thickness increase may be suppressed to provide a secondary battery with long-term lifespan and excellent high temperature capacity retention.
