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.

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

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 paper, the possibility of using lithium-ion batteries in hybrid stand-alone power sources is considered. The article gives a comparative analysis of the energy and performance characteristics, the service life of lead-acid and lithium-ion batteries. It is shown that the longer service life and the specific energy density, the absence of the need for constant monitoring of the main parameters and the ability to preserve the original capacity at increased discharge currents, open the possibility of using lithium-ion batteries in hybrid stand-alone power sources.

Abstract The demand for high-capacity lithium-ion batteries (LIB) in electric vehicles has increased. In this study, optimization to maximize the specific energy density of a cell is conducted using the LIB electrochemical model and sequential approximate optimization (SAO). First, the design of experiments is performed to analyze the sensitivity of design factors important to the specific energy density, such as electrode and separator thicknesses, porosity, and particle size. Then, the design variables of the cell are optimized for maximum specific energy density using the progressive quadratic response surface method (PQRSM), which is one of the SAO techniques. As a result of optimization, the thickness ratio of the electrode was optimized and the porosity was reduced to keep the specific energy density high, while still maintaining the specific power density performance. This led to an increase in the specific energy density of 56.8% and a reduction in the polarization phenomenon of 11.5%. The specific energy density effectively improved through minimum computation despite the nonlinearity of the electrochemical model in PQRSM optimization.
