Revealing the Real Electrode Reaction Process of Lithium-Ion Batteries by Coupling Kinetics and Thermodynamics Nonuniform reactions within porous electrodes are a common phenomenon during the charge–discharge processes of lithium-ion batteries, significantly impacting their rate performance.
The solvent or lithium salt is reduced or oxidized at the surface of the electrode during charging, and a portion of the resulting substance that is insoluble in the electrolyte will be deposited on the surface of the negative electrode or the positive electrode (Goodenough and Kim, 2010).
Conventional lithium-ion battery electrode processing heavily relies on wet processing, which is time-consuming and energy-consuming. Compared with conventional routes, advanced electrode processing strategies can be more affordable and less energy-intensive and generate less waste.
A good explanation of lithium-ion batteries (LIBs) needs to convincingly account for the spontaneous, energy-releasing movement of lithium ions and electrons out of the negative and into the positive electrode, the defining characteristic of working LIBs.
