一般描述

我们致力于为您提供更环保的替代产品,以符合“绿色化学的12项原则”的一项或多项原则要求。该产品为增强型,提高了能源效率。点击此处,查看更多详情。
溶于碳酸亚乙酯和碳酸二乙酯中的六氟磷酸锂溶液是一类可用于制造锂离子电池的电解液。锂离子电池由具有充放电循环的阳极、阴极和电解液组成。这些材料能形成更环保的可持续性电能储存电池。

应用

LiPF6 EC/DMC已被广泛用作溶剂中热稳定的电解质。它主要用于锂离子电池的制造。
液体电解质溶液在锂离子电池(LIB)中发挥关键作用,它是阴极和阳极之间的锂离子载体。因此,高纯度和电池级电解质溶液对锂离子电池的性能至关重要。最常见的LIB电解质衍生自锂盐溶液,如LiPF6 溶于碳酸烷基酯或溶剂混合物等非水溶剂中。电解质溶液的选择取决于运行条件,如温度和LIB中电极材料的性质。通过使用适当的添加剂可进一步改善电解质溶液的性能。
即用型电解质溶液具有不同的溶剂混合物形式,并且可以支持各种锂离子电池应用。这些溶液是高纯度和电池级的,因此也可作为LIB研究的标准品。定制配方可以通过混合电解质溶液或加入合适的添加剂来制备。

其他说明

操作说明:
  • 不要与玻璃设备一起使用
  • 所有工作都应在干燥空气下快速完成,以防止电解液吸收水分和溶剂蒸发。
