美国科学家呼吁政府关注“能源关键性元素”的开发与供应状况,以保证新技术开发与应用的基础“能源关键性元素贵胜黄金,可我们却将其当作垃圾对待,”麻省理工学院物理学教授、美国物理学会与材料学会合作研究小组的联合主席Robert Jaffe说。能源关键性元素(Energy Critical Elements,ECEs)是指那些可以改变人类能源获取、转化、及储存方式的化学物质。除了稀土金属元素,能源关键性元素还包括很多其他元素,如铟、锂、碲等。这些元素广泛应用于电动车、风机、太阳能电池等高新技术产品,但是目前,大多处于稀缺状态。
U.S. scientists urge the government to pay attention to the development and supply of “key elements of energy” so as to ensure the foundation for the development and application of new technologies. “The crucial element of energy is gold, but we treat it as rubbish.” " Robert Jaffe, a professor of physics at the Massachusetts Institute of Technology and co-chair of the cooperative research group of the American Institute of Physics and Materials, said. Energy Critical Elements (ECEs) are those chemicals that change the way human energy is harvested, transformed, and stored. In addition to rare earth metal elements, energy-critical elements also include many other elements, such as indium, lithium, tellurium and so on. These elements are widely used in electric vehicles, fans, solar cells and other high-tech products, but at present, mostly in a scarce condition.
