Abstract
(EN)
Provided are an electrolyte refining apparatus and an electrolyte refining method capable of reducing the hydrofluoric-acid content and the moisture content of an electrolyte by means of a simple method. The present invention provides an electrolyte refining apparatus that is for a battery electrolyte and that is provided with an absorbing apparatus 14 in which zeolite is accommodated, wherein the electrolyte refining apparatus is additionally provided with at least one of an anion exchange apparatus 12 that is connected to a preceding stage of the absorbing apparatus 14 and that accommodates a weakly-basic anion exchange resin and a cation exchange apparatus that is connected to a subsequent stage of the absorbing apparatus 14 and that accommodates a lithium-type strongly-acidic cation exchange resin.
