As reported in Nanotechnology, researchers from North Carolina State University, US, are using an industrially viable electrospinning technique and subsequent carbonization processes to fabricate porous carbon nanofibres (PCNFs). These prepared PCNFs can provide fast lithium charge/discharge kinetics, a short distance for both lithium-ion and electron diffusions, as well as the added pore space to accommodate the volume change accompanying lithium-ion intercalation. As a result, they exhibit remarkably improved lithium-storage capacities and excellent cycling performance when compared with graphite, which is presently used in state-of-the-art LIBs.

This novel, but simple and low-cost strategy may open up new opportunities to promote the research, development and commercialization of nanostructured anode materials for high-capacity and high-current LIBs., which are the dominant power sources for consumer devices and electric vehicles.
