Abstract: We have investigated theoretically the efficiency of lithium-ion batteries (LIBs), aiming to remove some problems such as fire and explosion of the LIBs in view point of based anode materials. Nano-boron nitride compounds have displayed great potential as anode materials for LIBs due to their unique structural, mechanical, and electrical properties. The measured reversible lithium ion capacities of graphene/(h-BN)_n/graphene(G/h-BN/G) based anodes are considerably improved compared to the conventional graphite(G)-based anodes. In this study boron nitride sheet has been localised inside the graphene as an option to enhance electrochemical ratio. Additionally, we have found that the structure of G/h-BN/G can be provide a suitable strategy for improving the performance of B-N-G based anodes because of its assembling into free-standing electrodes without any binder or current collector, which will lead to increased specific energy density for the overall battery design. In addition the modification of BN sheets and designing of X-G/h-BN/X-G structures (X = B and N) provides an extra strategy to improve the performance of LIBs. This study will help to create better anode materials which can replace graphite for higher capacity and better cycling performance in LIBs.
