中大利用护肤霜成分研发一款安全、 环保且具有稳定高电压的水系锂离子电池
由香港中文大学(中大)机械与自动化工程学系副教授卢怡君教授领导的研究团队最近为水系锂离子电池研究了一款新型的电解液,它的材料成本低且不易燃、毒性低、相对环保,更重要的是新型电解液应用到电池中能提供稳定的电压作日常使用,朝改善水系锂离子电池的性能迈进了一大步。研究结果已刊登于国际期刊《自然材料》。 锂离子电池的未来:从易燃有机液到安全水系 全球的经济以及人类的日常生活一直依赖着各类型电子设备,例如手机和笔记本电脑等等,而锂离子电池因为能提供相对稳定的能量,而且可以再充电重复使用,成为了这些可充电式电子产品的核心要素。然而,制造锂离子电池的主要材料之一是有机电解液,即使经过多年改良,这些电解液仍然含有毒性及高度易燃,有机会引发严重的安全问题 — 早年三星Note7手机爆炸、锂离子电池在波音公司787新型客机起火等事故就是其中的例子。 科学界近年深入研究以水系电解液取代传统有机电解液,因水的特质可解决易燃问题。然而,水系锂离子电池一直有个弊病,就是其电池电压和能量密度受到水电解限制。当电压高于1.23伏特,电解液中的水分子便会分解为氢气及氧气,大大影响电池运作及电压输出。增加水系电池电压的新兴做法是利用高浓度锂盐(每公斤21至55摩尔)制造人工固体电极介面及减少自由水含量,以改善水的稳定性,然而这个方法引起了对成本和毒性的忧虑。

单晶硅棒和多晶硅块—— 寻找最佳等级判定方法
单晶硅棒和多晶硅块的等级判定(以下简称“判定”)一直是光伏产业上游供应商最关心的问题之一。由于两种材料的生产工艺不同,它们的判定方法也有差别。 1.单晶硅棒的判定方法 对于单晶硅棒来说,业内的传统判定方法涉及多个步骤:先从硅棒头尾部切下厚晶圆,经热氧和化学腐蚀等处理步骤后,由操作员观察厚晶圆上是否有滑移线。如果有,还需继续向内切片;如果没有,也需要根据经验判断还需切除多少来让剩余部分不含任何黑边、黑环和黑心。这些都直接影响材料的最终电池效率。但是,这个方法检查一片厚晶圆不仅非常耗时,还很依赖操作员的个人经验。 为了缩短判断时间,部分生产商转而使用红外设备来纵向扫描整根硅棒,检测滑移线的位置。每根硅棒最快只需5分钟即可确定含有滑移线的部分。接下来,操作员可根据结果来切除硅棒的废料部分。但是,红外设备无法检测黑边、黑环和黑心等缺陷,因此操作员仍需根据经验向内切割。随之而来的问题是,切多少可以确保完全去除废料,并且不浪费优质部分呢? 近年来快速兴起的光致发光(PL)成像技术给这个问题带来了及时的解决方案。PL是材料吸收光子后的光辐射。 在光伏硅基材料上应用这个原理,带来了PL成像检测技术:使用模拟太阳光照射硅片或电池片,并用专用的PL镜头来获得样本的PL成像。
