据英国《每日邮报》11月12日报道,科学家们已发现一种超小黄铁矿量子点,可将智能手机的充电时间大大缩减至30秒。量子点是一种半导体纳米粒子,比人们发丝宽度小1万倍。这些纳米粒子拥有独特的电性能,改造后可用于电池充放电。但直至目前为止,量子点只能充放电几次。

目前,相关研究人员发现用黄铁矿(又名愚人金)制造量子点可提高量子点的充电性能,更快速地给手机充电。

该研究小组由美国范德堡大学机械工程专业助理教授Cary Pint领导。他对黄铁矿感兴趣,主要因其蕴藏丰富。它是煤炭生产中的副产品,价格低廉,常被应用于一次性锂电池生产。

Pint认为研究人员虽已证明了纳米材料可以大大提升电池性能,但该材料仍存在局限性。当粒子尺寸小于10纳米时,该粒子就会跟电解质发生化学方应,所以只能充放电几次。
