日本原子能研究开发机构近日宣布,其研究小组开发出了一种从海水中高效提取锂的技术。锂是一种稀有金属,作为锂电池的原料,在个人电脑和电动汽车等领域得到广泛应用。全球陆地蕴藏的锂有限,据推测只有约1 400万吨,不过海水中却有丰富的锂,据估计达到2 300亿吨,但是由于浓度很低, Japan’s Atomic Energy Research and Development Agency announced recently that its research team has developed a technology that efficiently extracts lithium from seawater. Lithium is a rare metal that is widely used as a raw material for lithium batteries in fields such as personal computers and electric vehicles. The limited lithium reserves on the earth’s land are presumed to be only about 14 million tonnes, although there is an abundance of lithium in seawater, which is estimated at 230 billion tonnes but due to low concentrations,
