利用吸附板法从海水中收集锂锂是具有各种工业用途的元素,最近引人注目的是用作高能二次电池的电极材料。而日本尚未证实有锂资源赋存,与其它许多资源一样必须全部从国外进口。为此,从确保资源和再回收的观点考虑,进行了从国内地热水和海水等自然水中收集锂的研究,以及从用过的锂电池等工业废物中回收锂的研究。特别是关于从海水中收集锂的研究,随着锂吸附剂性能的显著提高,现已将其纳入工业实用化的研究项目中。在一些研究报告中,采用锂吸附剂与海水接触的方法,这主要是将聚氯乙烯作粘合剂,把粉末状的锂吸附剂制成粒状放在吸附槽内,使之与海水接触 The use of adsorption plate method to collect lithium from seawater is an element with a variety of industrial uses, the most notable recent is used as a high-energy secondary battery electrode material. While Japan has not confirmed the existence of lithium resources, like many other resources, they must all be imported from abroad. For this reason, from the viewpoint of securing resources and recycling, studies have been conducted to collect lithium from natural water such as domestic geothermal water and seawater, as well as to recover lithium from industrial waste such as used lithium batteries. In particular, research on the collection of lithium from seawater has been incorporated into industrial practical research projects with the significant increase in the performance of lithium adsorbents. In some research reports, the use of lithium adsorbent and seawater contact method, which is mainly used as a binder of polyvinyl chloride, the powdered lithium adsorbent made granular placed in the adsorption tank, so that contact with the sea water
