锂离子电池硅基负极材料用CMC胶粘剂研究进展

Research progress of CMC adhesive for lithium ion battery silicon-based negative materials

简单介绍了国内外锂(Li)离子电池硅(Si)基负极材料的研究进展,指出了有机溶剂型油性聚偏氟乙烯(PVDF)胶粘剂在Li离子电池应用中存在的问题,并分析了CMC(羧甲基纤维素)胶粘剂在Li离子电池Si基负极材料中的应用现状,另外还探讨了Li离子Si基负极材料用CMC胶粘剂的作用机制。最后就CMC胶粘剂对Si基负极材料性能的提升进行了展望。

The research progress of lithium （Li） ion battery siiicon- based negative materials was briefly introduced at home and abroad. The existing problems of Oily polyvinylidene fluoride （PVDF） adhesive with organic solvent were pointed out in application of Li ion battery, and the application status of CMC （carboxymethyl cellulose） adhesive was analyzed in Li ion battery silicon-based negative materials, also the action mechanism of CMC adhesive for Li ion battery silicon-based negative materials was discussed. Finally, the promoting of CMC adhesive on properties of silicon-based negative materials was expected.
