Title: New High Energy Nanofiber Anode Materials

Abstract

The objective of the work is to use electrospinning technology to integrate dissimilar materials (lithium alloy and carbon) into novel composite nanofiber anodes, which simultaneously have high energy density, reduced cost, and improved abuse tolerance. The nanofiber structure also allows the anodes to withstand repeated cycles of expansion and contraction. These composite nanofibers are electrospun into nonwoven fabrics with thickness of 50 μm or more, and then directly used as anodes in a lithium-ion battery. This will eliminate the presence of non-active materials (e.g., conducting carbon black and polymer binder) and result in high energy and power densities. The nonwoven anode structure also provides a large electrode-electrolyte interface and, hence, high rate capacity and good low-temperature performance capability.
