锂离子电池电解质盐LiPF6中微量水的测定
MEASUREMENT OF TRACE WATER IN LiPF6 ELECTROLYTE SALT OF LITHIUM ION BATTERY
【摘要】 采用把库仑法和卡尔-菲休法有效结合的库仑滴定法测定锂电池电解质中微量水份,对电解质盐六 氟磷酸锂(LiPF4)样品的测定表明,该方法灵敏度为1μg,精密度高,结果比较理想。
【Abstract】 In this article, coulomb titration method which combined coulomb method with Karl-Fischer titration method was adopted to detect trace water in electrolyte of Lithum ion battery. The results showed that the sensitivity of this method is up to 1μg and precision is good.
