A Long-Life Lithium Ion Oxygen Battery Based on Commercial Silicon Particles as the Anode. Energy Environ. Sci. 2016, 9, 3262–3271. [Google Scholar] [CrossRef] Lökçü, E.; Anik, M. Synthesis and Electrochemical Performance of Lithium Silicide Based Alloy Anodes for Li-Ion Oxygen Batteries. Int. J. Hydrogen Energy 2021, 46, 10624–10631.
Electrochemical reactions of lithium–oxygen battery The lithium–oxygen battery consists of a porous carbon cathode designed to promote oxygen diffusion and reduction and a pure lithium metal anode as shown in Fig. 3. The two electrodes are separated by a lithium-ion conducting electrolyte.
The table indicates that as the solubility (indicated by α) of oxygen in the electrolyte increases, the specific capacity of the battery also increases due to a larger concentration of oxygen available for the reduction reaction.
Lithium ion battery is the indispensable power source of modern electric vehicles. It is rechargeable and have high energy density than other commercially available batteries. Due to its light weight it also used in smart phones, laptops etc. Each battery consists of number of batteries generally called cells.
Analysis of the rate of reaction between singlet oxygen and the solvent suggests that during a typical cycle of the lithium–oxygen battery, singlet oxygen would be responsible for approximately 0.002% capacity loss each cycle, which is not consistent with the 5–10% found in practice.
