集流体重量占锂电池电芯重量的 15%左右,是锂电池重要的组成部件之一.目前集流体的性能无法很好地满足所有体系电池的要求,因此文章结合市场生产工艺,总结了锂电池中不同集流体在表面改性、表面功能化涂层等方面的最新研究,介绍了目前市场上应用的集流体,并进一步探讨了集流体的未来发展趋势.
The weight of the current collector is about 15%of the weight of the lithium-ion battery cell,which is one of the important components of the lithium-ion battery.At present,the performance of current collectors cannot meet the requirements of all batteries well,so this paper combined with the market production process,summarized the different current collectors in lithium-ion batteries in the surface modification,surface functional coating and other aspects of the latest research,introduced the current collectors applied in the recent market,and further discusses the future development trends.
