Novel approach toward a binder-free and current collector-free anode configuration: highly flexible nanoporous carbon nanotube electrodes with strong mechanical strength harvesting improved lithium storage

In this work, we developed a novel flexible nanoporous carbon nanotube film to use as a binder-free and current collector-free anode electrode for lithium ion batteries, providing a new approach to flexible energy devices. The proposed novel anode configuration shows better cycling performance and rate capability than the conventional electrode architecture. Moreover, this unique configuration exhibits good flexibility and robust mechanical strength, which has the potential to be applied to flexible lithium ion batteries. Our findings may provide a new anode configuration for lithium ion batteries with improved cycling stability and rate capability.
