What is the insertion potential and deposition potential of Li+/Li?

The insertion potential is around 0.2 V vs. Li+/Li, while the deposition potential is below 0 V . Despite this, polarization caused by factors such as ohmic drop, diffusion overpotential and charge transfer overpotential is the main contributor to lithium deposition, making it a complex process.

Can OCV increase the power density of lithium ion batteries?

OCV is one of the main indices to evaluate the performance of lithium ion batteries (LIBs), and the enhancement of OCV shows promise as a way to increase the energy density. Besides, the severe potential drop at the interfaces indicates high resistance there, which is one of the key factors limiting power density.

Where is the potential drop in a lithium battery?

It can be seen from the porous electrode model that lithium ion diffusion path is very short within the electrode particles, resulting in generally small resistance of the battery pole pieces. Therefore, for the traditional battery structure, the potential drop usually lies in the electrolyte section.

How do you describe lithium insertion and extraction in a charge/discharge reaction?

During the charge/discharge processes, the lithium insertion and extraction can be generally described using the following reaction: (2) Li x i [cathode] + (x j − x i) Li [anode] ↔ Li x j [cathode] + [anode] where xi and xj indicate the solid solubility limits of the intercalation reaction.
