Abstract:

Lithium battery electrolyte additives are a class of high value-added electronic chemicals that are not used in large amounts in lithium batteries, but play an important role in improving the high and low temperature performance of lithium batteries, increasing their service life and cycle times. With the long-term development of downstream applications such as lithium batteries, the demand for additives continues to grow. However, the poor transfer performance of traditional kettle reactors results in unsatisfactory product quality stability and severe pollution. Microreactors have the advantage of efficient dispersion and mixing of fluids at the micron scale, which is an effective means to improve production efficiency and reduce production costs, and have received increasing attention in the synthesis of lithium battery additives. In this paper, based on the excellent transfer performance of microreactors, the application of microreactors in the synthesis of cyclic ester lithium-ion battery electrolyte additives is reviewed, and the research direction in the field of microchemical synthesis of additives is prospected.

Key words: microreactor, synthesis, transport, electrolyte additives of lithium battery, electronic chemical

摘要:

锂电池电解液添加剂是一类在锂电池中用量不大,但对改善锂电池高低温性能,提高使用寿命和循环次数等方面发挥重要作用的高附加值电子化学品。随着锂电池等下游应用长期向好地发展,添加剂的需求量不断增长,但传统的釜式反应器由于传递性能不佳导致产品质量稳定性较差且污染严重。微反应器在微米尺度对流体有着高效分散和混合的优势,能显著提高生产效率、降低生产成本,在锂电池添加剂合成方面受到越来越广泛的关注。本文结合微反应器优异的传递性能,系统综述了微反应器在环酯类锂离子电池电解液添加剂合成中的应用进展,并对添加剂的微化工合成领域的研究方向进行了展望。
