    摘要: An electric double layer capacitor is provided that includes a positive electrode having a currect collector combined with a polarizable electrode material composed mainly of activated carbon, a negative electrode having a current collector of porous metal incapable of forming an alloy with lithium, combined with a carbonaceous material having lithium ions occluded by a chemical method or an electrochemical method to a carbon material capable of occluding and releasing a lithium ions, and a nonaqueous electrolyte containing a lithium salt. The negative electrode is supported on a current collector of porous metal having a thickness of 0.1 to 1 mm and a porosity of 5 to 80%.

    摘要: An electrolysis of an aqueous solution of sodium chloride is carried out by employing a fluorinated cation exchange membrane having an ion-exchange capacity of 0.8 to 2.0 meq/g dry polymer and having carboxylic acid groups as functional groups and maintaining a concentration of an aqueous solution of sodium hydroxide in a cathode compartment in a range of 20 to 45 wt. % and maintaining a calcium concentration in the aqueous solution of sodium chloride to lower than 0.08 mg/liter.The purification of the aqueous solution of sodium chloride to reduce the calcium concentration is carried out in a system comprising the first and second chelate ion-exchange towers which are connected through a detector for detecting impurities in the aqueous solution.
