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.
The factors affecting the apparent performance of lithium metal negative electrodes are as follows: various characteristics of the freshly deposited layer of lithium metal (morphology, nucleus shape, specific surface area), electrolyte composition, and the results of the interaction between the two (i. e., the formation of SEI).
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
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 anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
In the context of ongoing research focused on high-Ni positive electrodes with over 90% nickel content, the application of Si-negative electrodes is imperative to increase the energy density of batteries.
