Core-Shell Structured Nanohybrid Template for Sodium Metal Battery, Sodium Metal Battery Using the Same And Method for Preparing the Same

摘要

A catalyst mold for a sodium metal battery, wherein the catalyst mold includes a core shell structure coated with a carbon layer having a nitrogen functional group on a metal nanofiber core, a nanohybrid mold having a core shell structure for a sodium metal battery, and a sodium metal battery using the same And a manufacturing method thereof is disclosed. According to the introduction of such a nano-hybrid structure, the overvoltage generated in the sodium metal nucleus is greatly reduced due to the large specific surface area and the many catalytic sites provided by the carbon layer, and the Coulomb efficiency (CE) can be dramatically increased. Moreover, excellent chemical stability can ensure excellent life stability even in repeated metal deposition/desorption processes of several thousand times or more.
