In the present time, the rechargeable lithium-ion battery is being commercialized to meet the sustained market’s demands. To design a more reliable, safe, and efficient Li-ion battery, a 3-D simulation study has been presented in this paper. In this study, a lithium-ion coin-cell is proposed which has LiFePO4 as a positive electrode with a thickness of 1.76 µm, carbon as a negative electrode with a thickness of 2.50 µm and Celgard 2400 polypropylene sheet as a separator between the electrodes with a thickness of 2 µm. The proposed Li-ion battery has been designed, analyzed, and optimized with the help of Multiphysics software. The simulation study has been performed to analyze the electrochemical properties such as cyclic voltammetry (CV) and impedance spectroscopy (EIS). Moreover, the electrical and thermal properties at the microscopic level are investigated and optimized in terms of surface potential distribution, the concentration of electrolyte, open circuit, and surface temperature with respect to time. It has been noticed that the peak voltage, 3.45 V is observed as the temperature distribution on the surface varies from 0 OC to 80 OC at a microscopic scale with different C-rates. The analysis of simulation results indicates a smoother electrode surface with uniform electrical and thermal properties distribution resulting in improved reliability of the battery. The performed simulation and optimization are helpful to achieve control over battery performance and safe usage without any degradation of the environment.©2020. CBIORE-IJRED. All rights reserved.

Today the United States is heavily reliant on the lithium-ion battery as most portable devices and electronics run on it. Current innovations are also looking on how to maximize it on the grid and transportation. This paper will look at three sovereign states and their current initiatives on Li-ion battery recycling: US, European Union, and China. The term initiative is used loosely as the information is not permanent in most policies or plans. Li-ion battery recycling initiatives are crucial to look at because used and wasted Li-ion batteries can disrupt public health and Li-ion batteries are expected to be a factor for effective material supply for future battery production especially in transportation, like the Tesla Roadster.

Tin oxide/sponge carbon composite (SnO2/C) is synthesized by solvothermal reaction. The expected electrode materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectrum. Related electrochemical properties are carried out by battery comprehensive testing system. The composite could remain its specific capacity at 660.5 mAh g−1 after 200 cycles and behaved superior rate performance. The experimental results show that SnO2/C composite not only owned improved conductivity but also stable frame structure during lithiation/delithiation processes. So SnO2/C composite behaved higher reversible specific capacity and rate performance than those of pure SnO2 or SnC2O4. Based on its outstanding electrochemical performances, the SnO2/C anode electrode is a hopeful candidate for future application in lithium ion battery system.
