Growth of Ru-Modified Co3O4 Nanosheets on Carbon Textiles toward Flexible and Efficient Cathodes for Flexible Li-O2 Batteries.

A flexible and highly efficient air cathode is fabricated via a simple electro‐deposition approach. This cathode exhibits a series of considerable electrochemical performances, in particular a good cycling performance (more than 70 cycles with the capacity limited 1000 mA h g−1). Based on this flexible cathode, a Li–O2 battery with flexible properties is also assembled, which can power a commercial LED normally. [ABSTRACT FROM AUTHOR]
