为能够有效、经济且工艺简单地去除锂离子电池非水电解液中的微量水 ,根据离子交换原理对普通 4A分子筛进行锂化处理制备锂化分子筛。经实验验证 ,这种分子筛既能满足除水的要求 ,又能大大降低因和 Li+发生离子交换而导致的杂质离子 Na+的引进 ,从而保证了电池的循环性能 ,因此具有很大的工业应用及推广价值。 In order to be able to effectively, economically and technologically simply remove trace amounts of water from a nonaqueous electrolyte of a lithium ion battery, lithiated molecular sieves are prepared by lithiation of ordinary 4A molecular sieves according to the ion exchange principle. The experimental verification shows that the molecular sieve can not only meet the requirements of removing water but also greatly reduce the introduction of impurity ions Na + resulting from the ion exchange with Li + to ensure the cycling performance of the battery. Therefore, the molecular sieve has great industrial application and Promote value.
