Li-B Alloy as Anode Material for Lithium/Sulfur Battery

Abstract

The electrochemical performance of Li-B alloy as anode for lithium/sulfur battery is firstly investigated. Compared with the common metal Li anode, Li-B alloy has better behaviors in restraining the formation of dendritic lithium, reducing the interface impedance of electrode and improving the cycle performance of the battery due to its unique structure which contains free metal lithium filled in the fibrillar network framework of Li/B compound. Test results show that the Li-B alloy has great potential as a promising anode material for lithium/sulfur battery.
