We report the stability and electronic structures of the double wall boron nitride nanotubes (DWBNNTs) due to interaction with anode lithium ion batteries (LIBs). Nano-Boron Nitride compounds have displayed great potential as anode materials for lithium ion batteries due to their unique structural, mechanical, and electrical properties. The measured reversible lithium ion capacities of SWBNTs//(Li)n//SWBNTs based anodes are considerably improved compared to the conventional graphite-based anodes. In this study (5, 5)@(7, 7) DWBNNTs, (5, 5)@(8, 8) DWBNNTs and (5, 5)@(9, 9) DWBNNTs have been localized inside the LIBs as an nano-capacitor to enhance electrochemical ratio of lithium ion capacities. Additionally, we have found the structure of (5, 5)@(8, 8) DWBNNTs can be to improve the capacity and electrical transport in anode-based LIBs. Therefore, the modification of cylindrical of BN and design of SWBNTs//(Li)n//SWBNTs structures provide strategies for improving the performance of material based anodes in LIBs. SWBNTs//(Li)n//SWBNTs could also be assembled into free-standing electrodes without any binder or current collector, which will lead to increased specific energy density for the overall battery design.

Abstract: In this study Boron nitride 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 LIBs. Therefore, the modification of BN sheets and design of X-G/ (h-BN)n/X-G structure provide strategies for improving the performance of BN-G-based anodes. X-G/(h-BN)n/X-G could also be assembled into free- standing electrodes without any binder or current collector, which will lead to increased 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

In this work the concentration of Li/Li+ has applied for increasing the efficiency of Lithium ion batteries. Various numbers of lithium and lithium cations have been simulated as diffused atoms in graphite as anode materials. We have found the structure of (G// (h-BN) //G) can be to improve the voltage and electrical transport in anodic sheets-based LIBs. This system could also be assembled into free-standing electrodes without any binder or current collector, which will lead to increased specific energy density for the overall battery design. Therefore, the above modification of BN-G sheet and designing of this kind structure provide strategies for improving the performance of material based anodes in LIBs.

High Flexibility

In this work, innate free-standing and flexible anode composed of entangled N-doped carbon nanotubes (CNTs) is fabricated by a facile annealing method following a simple compression without needing any tedious processing operations. The well cross-linked CNTs of the resultant free-standing anode enable robust diffusion channels for lithium ions and high flexibility. Served as the anode in lithium-ion batteries (LIBs) without the utilization of binder and current collector, the fabricated free-standing electrode can deliver a reversible area capacity of 2.14[Formula: see text]mAh[Formula: see text]cm[Formula: see text] at 1[Formula: see text]mA[Formula: see text]cm[Formula: see text] with superior cycling stability and excellent rate capability. The obtained reversible area capacity for the fabricated free-standing electrode material is much higher than that of the commercial graphite anode ([Formula: see text][Formula: see text]mAh[Formula: see text]cm[Formula: see text] at 1[Formula: see text]mA[Formula: see text]cm[Formula: see text]). Furthermore, the assembled full flexible battery utilizing the fabricated free-standing electrode also exhibits attractive performance and can substantially supply power for an electronic watch at flat and 180∘ bending positions, indicating the promising application in flexible electronic devices.
