Method and Use of Ceramic/Carbon Composite Nanofibers as Anode Materials for Lithium-ion and Sodium-ion Batteries
Description
The present invention concerns composite-nanofiber electrodes, specifically metal –oxide/carbon (MOx/C) and metal-sulfide/C (Ms/C) composite nanofibers with high discharge capacity, and good cycle life for use as anodes in lithium-ion and sodium-ion batteries (LIBs & SIBs).
Problem
An important obstacle in the development of electric power applications is the poor electrochemical performance of current materials in commercial lithium-ion batteries.
Solution
Using centrifugal spinning method, our technology produces composite nanofibers out of tin, tin-sulfide, and tin-nickel binaries to use as alternative anode electrodes for lithium-ion and sodium-ion batteries. These materials have demonstrated promising results in energy density and cycling performance.
Value Proposition
The process method employed in this technology is a viable means for large scale production, as well as low cost, of metal sulfide/oxide-based composite fibers for metal-ion battery electrodes.
