Real-time monitoring of NE potential is highly desirable for improving battery performance and safety, as it can prevent lithium plating which occurs when the NE potential drops below a threshold value. This paper proposes an easy-to-implement framework for real-time estimation of the NE potential of LIBs.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.

The mainstream LIBs with graphite negative electrode (NE) are particularly vulnerable to lithium plating due to the low NE potential, especially under fast charging conditions.
