Jae-Yong Choi, Dong Jin Lee, Yong Min Lee, Young-Gi Lee, Kwang Man Kim, Jung-Ki Park and Kuk Young Cho Silicon Nanofibrils on a Flexible Current Collector for Bendable Lithium-Ion Battery Anodes Advanced Functional Materials 23
A nanofibril structured silicon anode on a flexible current collector is demonstrated for a high energy capacity bendable lithium ion battery. The flexible batteries show over 99% coulombic efficiency with the reversible capacity over 30 cycles at 2000 mAh g−1. This new, flexible current collector suggests a new approach to utilize Si anodes for flexible batteries.
