Graphene/(h-BN)n/X-Doped Graphene As Anode Material In Lithium Ion Batteries (X = Li, Be, B And N)

Abstract

In this study boron nitride (BN) sheet has been localized inside two X-graphene electrodes as an option to enhance the electrochemical ratio. Additionally, we have found the structure of X-G/(h-BN)n/X-G (n = 2-5) can improve the capacity and electrical transport in C-BN sheet-based lithium ion batteries (LIBs). Therefore, the modification of BN sheets and design of X-G/(h-BN)n/X-G structure provide strat-egies for improving the performance of BN graphene based anodes. X-G/(h-BN)n/X-G could also be as-sembled into free- standing electrodes without any binder or current collector, which will lead to in-creased specific energy density for the overall battery design. In this work the measured reversible lithium ion capacities of X-G//(h-BN)//X-G (X = Be, B, N) based anodes are considerably improved compared to the conventional graphite-based anodes.
