摘要

本文以粗糙硅片为模板，研制了一种厚度为5.6 um, Rq为637.98 um的粗糙柔性聚对二甲苯集流器。与容量为0.2C的样品相比，粗糙集流器在8C充放电倍率下的容量保持率达到31%，比使用扁平集流器的样品高2.1倍。

A thin film and high roughness flexible current collector for high charging/discharging rate flexible Li-ion battery

In this work, a 5.6 um thick, Rq 637.98 um roughness flexible Parylene C current collector is developed by using a rough Si wafer as a template. The rough current collector achieves 31% capacity retention @ 8C charging and discharging rate comparing the capacity @ 0.2C, which is 2.1 times higher than the sample using a flat current collector.
