Introduction Conductions remain to be the main hindrance to improvement in lithium-ion (also referred to as Li-ion) batteries. Despite the technological advancements in the recent world, this barrier is seen to remain for foreseen future. A comprehensive survey on the conduction phenomena in Li-ion cells is done to gain a good understanding of the process and to enable a breakthrough in technology (Azevedo, Baldan, and Ferreira 2). A good example of a family of rechargeable batteries is the lithium-ion (also referred to as Li-ion battery). Lithium ions move from the negative electrode to the positive electrode when discharging. During discharging, the lithium ions move from the positive electrode to the negative electrode. The safety characteristics, performance, and chemistry vary in the different types of LI-ion. Li-ion electrochemical cells apply lithium compound as the electrode material in place of metallic lithium. Enhanced electronic conductivities coupled with ionic diffusivities in anode and cathode substances or materials are making it possible for improvements in the capacity of lithium batteries. The cathode in this family of batteries is made of metallic oxides, which have low electronic conductivity. The electrolyte is tuned to accept ions while at the same time forming a safe and impenetrable insulating barrier (Azevedo, Baldan, and Ferreira 4). Researchers in this field face various challenges. These challenges include the low electrical and ionic electronic conductivity values in the electrochemical cells and the unclear relationship between electrical conduction and ionic conductivity in cathode materials. Other challenges the researchers face are the constantly changing conduction properties of the anode and the difficulty in measuring the conductivity and microstructure of the solid-electrolyte film. To design improved materials, the models and materials of battery cells require the best available estimates for diffusivity and conductivity. There is continuous improvement of the knowledge of cell response, which has been contributed by the different models of molecular and atomic, and fibers and continuum scale (Bard and Mirkin 16). The knowledge about conduction phenomena is still scarce since many researchers do not tackle the problem; instead, they touch narrowly on cathode and anode. A compressive survey on conduction phenomena is done in this paper. Different methods are used to collect data. These methods are simulation, experimental and theoretical studies. The main objectives are to survey electrical and ionic conduction fundamental theories, the relationship between ionic and electrical conduction for Lin2o4, LiMn2O4, and LiFePO4, and review of the phase change in anodes made of graphite (pourbaix 90).

The Positive Temperature Coefficient (PTC) switch is used to prevent the battery from overheating. The separator separates the positive and the negative electrodes while allowing electrons to move through. Lithium cobalt oxide makes the positive electrode while the negative electrode is made of carbon. Proposed approaches Electrons and ions conduct
