c) PC charging mitigates Li-ion depletion at the electrode–electrolyte interface, thereby altering the electrolyte decomposition and SEI reformation pathway and suppressing second-order reduction of the carbonate-based electrolyte that leads to the formation of inorganic Li salts (e.g., Li 2 CO 3).
Furthermore, the NMC532 and graphite electrodes suffer from cracking in structure, along with electrode exfoliation, which also contributes to capacity loss. In this paper, we show that PC charging can mitigate these issues. While it is difficult to rationalize the approach, a few general arguments can be made.
It is possible to store charge via transferring electrons, which causes changes in the oxidation states of the material. According to Faraday’s laws (thus the name), electroactive materials have a high electrode potential. In some cases, there is a possibility of pseudocapacitance. Indirect energy storage is similar to that of a battery.
A protrusion with 4 μm height as a site for dendritic growth in the geometric center is set on the surface of negative electrode to imitate its non-uniform morphology .
As a result, on the positive electrode, there is an accumulation of negative charges which is attracts by positive charges due to Coulomb’s force around the electrode and electrolyte. Electrolyte–electrode charge balancing results in the formation of an EDL.
