文摘

Flexible/bendable electronic equipment has attracted great interest recently, while the development is hindered by fabricating flexible/bendable power sources due to the lack of reliable materials that combine both electronically superior conductivity and mechanical flexibility. Here, a novel structure of manganese oxide, like fabric foam, was constructed, which was then cocooned with a carbon shell via chemical vapor deposition. Serving as a binder-free anode, the self-knitted MnO₂@Carbon Foam (MCF) exhibits high specific capacitance (850鈥?50 mAh/g), excellent cycling stability (1000 cycles), and good rate capability (60 C, 1 C = 1 A/g). Moreover, a flexible full lithium battery was designed based on an MCF anode and a LiCoO₂/Al cathode, and the outstanding performance (energy density of 2451 Wh/kg at a power density of 4085 W/kg) demonstrates its promising potential of the practical applications.
